    Fluke 233 Meter Review - Important Follow-up

    Zad

      I have had my Fluke 233 just over 4 months now, over which time it has  had pretty light use. Which is why what I am about to say is a bit of a  surprise.

      In my review I wrote:

      Batteries.  400  hours  estimated life is  excellent. That probably works out at 3 to 4  years  usage for me. But,  when they go, it does mean potentially 5  batteries  have to be replaced.

      I have used it for maybe 5 hours use  at the outside, and not at all for the past month or so (sadly, my  engineering has mostly been on paper or PC recently). That doesn't sound  much, but it adds up to quite a few voltage and resistance  measurements.Anyway, I came to use my Fluke 233 today and this met me:

       

      http://i222.photobucket.com/albums/dd237/Zadpics/FlatBattery.jpg

       

      Pretty much running on empty! Removing the remote head results in a BATT  warning and no measurements are possible. If I am going to be  installing a new set of 5 batteries every 4 months then it becomes a very expensive meter! I had thought that using high energy density AA  cells was a good idea (the cells it came with were brand new Duracells  with a very long use-by date), but maybe Fluke are covering up some  nasty quiescent current use. Swapping out the batteries allowed me to test  the off-load voltages, which were all around 0.95-0.96 Volts, so that rules out a rogue cell failure. My investigations with my trusty Fluke 77 (battery age 4 years) revealed the following:

      Body power consumption, power ON = 3 to 6mA
      Body power consumption, power OFF = 0.9 to 1.1mA
      Display unit, power ON = 3 to 3.6mA
      Display unit, power OFF = 1mA

       

      Looking at http://www1.duracell.com/oem/Pdf/new/MX1500_US_UL.pdf the nominal capacity for <5mW drain is 1600 to 2300mAh (to 1 volt). 2300mAh at 1mA, is 95.8 days...

       

      You  will note that an "on" life of 3mA is 766 hours, and 6mA is 383 hours,  which averages close to the specified taget of "around 400 hours".  Presuming you use your meter 24 hours a day, and don't actually switch  it off...

       

      Given the recently found RF vulnerability in the Fluke 87 V, it does   make me wonder if Fluke are taking their eye off the ball. It surely cannot be right that a   meter eats a set of 5 cells in 4 months, especially given such light   usage. This is certainly not the sort of meter to leave in your tool case, because chances are that the batteries will be flat when you need it.

       

      If any other Fluke 233 owners have experienced any similar failures, please let me know!

       

      If any Fluke reps see this: Is there a known fault with the 233? Because this does look like a bit of a killer design issue.

          Hello Mike,

           

          Coincidentally, the batteries of my Fluke 233 died last week, after approximately 4 months of light use. As I suspected in my review and which you confirmed above, it is not possible to turn off the Fluke 233 completely, causing it to eat batteries, even when it is not in use.

           

          In their next wireless multimeter, it might be wise for Fluke to include a On/Off switch on the wireless module, to allow users to switch the meter off completely when it is not in use. For the Fluke 233, I can only recommend removing the batteries when the meter is not in use, although this is obviously not a very elegant solution.

            I have experienced the same problems with my unit (as Mike & Patrick have noted above) ... I have used my unit very 'lightly' ... total "ON" time is probably < 20-hours.  I always turn if off when I am not using it to conserve on batteries ... well, so I THOUGHT. 

             

            The batteries are being slowly depleated even without use ... seems like a design flaw (or oversight).  I wonder if there is a way to fix this with a firmware update that would power down the unit completely?

                I'm glad I checked this forum today, I think the auto-email thing ceased to function a few months ago. I think it is about time for me to follow this up directly with Fluke. This is now at least 4 people who I know of that have experienced unacceptably short battery life. I'm not sure they can be flash upgraded, as neither section has anything resembling a JTAG connector. There are some test points, but they look more analogue in nature. Let us see what Fluke have to say.

                    Hello Viewers, The 233 is unique in its design and implementation with its wireless display utilizing both iR and RF communication between the meter base and the remote display. While docked the meter utilizes iR communication and when the display and base are separated RF communication is used. When new the meter is shipped with paper tabs inserted into the battery compartment for both the base and the display to keep the batteries disconnected from the meters power supplies. This is to insure that the batteries have a full charge and the customer gets the longest battery life possible. The reason for a short battery shelf life is that when the meter is turned off and the display is mated, the iR communication is still active. This was done by design to give the user the most flexibility when using their 233 meter. The design allows the user to power on and to wake up the meter while the display and body are disconnected. It simplifies the meters operation. This use model was important to customers during our initial research for the 233. The alternative would have been to have two separate power buttons, one for the base and one for the display. Our research indicated that this was a less attractive solution to our implementation of one power up option for both parts. The trade off is the unit consumes more power but gives the users more flexibility. If the meter were to go into battery save mode and the iR communication were not active, the display and meter body would need to be re-connected before the display could power up. This option and two separate power up processes were not attractive in our research. To optimize the battery life, for intermittent use or extended periods of storage, it is recommended that the paper tabs be re-inserted into the battery compartments or the batteries be removed completely.

                        I never pay more than 50 cents each for premium alkaline cells, Duracell, Energizer, etc..  Usually less.  I would not consider 7 - 8 dollars per year to be "Very Expensive"

                            K5HJ, unfortunately we don't all live in countries where premium alkalines are 50c each. £150 over 10 years is utterly ridiculous.

                             

                            On a more positive note, Jim, might I suggest some inexpensive yet effective design amendments for the next revision of the 233? Principally that the IR transmit LEDs are driven through higher value current limiting resistors. The range only need be short and they are currenly bright enough to be seen by my camera across the other side of the room. Additionally, rather than running the IR transmit ALL the time, reduce it to a couple of bursts a second. By my calculations, this would increase battery life to a more reasonable 2.5 years. Latency between operating the power switch and activating the display should not be compromised in any way, as the IR will start to transmit on power-up and the head unit should be interrupt driven anyway. It just means that there will be a maximum delay of 0.5 seconds when undocking/docking when switched off, which the user will not notice anyway as the unit is off.

                             

                            When it comes to a re-design, docking and undocking detection must be a priority. There are many passive methods that can be used to detect a status change, whether it be a pair of switches, a magnet+sensor, or a shorting contact built into the docking rails. These would all allow the controllers to fall back to a micropower state rather than being active all the time, driving a current hungry output. As they replace the IR functionality, none of these methods would compromise functionality demanded by your marketing executives.

                                It seems to be a problem with other Fluke instruments as well.

                                My Fluke 123 scopemeter is suffering even worse from this.

                                I use it maybe 15 minutes once a month, and every second time I need it, it's out of power, partly due to 1mA standby current, partly due to poor rechargeable batteries, that sure were cheap for Fluke to include, but not really suitable for the purpose.

                                At least Fluke could write this in their datasheet, instead of letting people find out after paying for something that does not work as expected.

                                 

                                ......add to that, a software error that does not allow for a battery refresh, and you see where this is heading.

                                 

                                This by the way seems to go for the TiS cameras as well.

                                 

                                I will go as far as saying that this was the last Fluke product I intend to buy, as Agilent offers at least the same or better quality these days, and cheaper.

                            Regarding the 233 ... At the time, I had just accepted the poor battery life ... then got frustrated and started to research the internet for a solution.  Sure enough ... Fluke will update the firmware at no charge (and provide calibration).  You are responsible for the shipping charges to send the item to them, however.

                             

                            It is better to call them:  888.993.5853 ... I experienced problems with their website.

                             

                            The "music on hold" is very distorted (if you call them and are put on hold) .. I brought this to their attention and they just kind of laughed it off ("yeah, I've heard that before").  You would think that a company that is associated with precision measurement equipment would have a more professional telephone system.

                             

                            I will update this post when I receive the meter back from Fluke.

                                Well, I must say Fluke is trying hard. The concept of Fluke 233 is very good and I hope they keep this product alive for a long time like the 87V. I hope they don't think the CNX series can replace this.

                                 

                                Yes, there is a firmware update to improve the battery life. However, I think (I am not able to get confirmation from Fluke), there is also a hardware change for those serial nos >22500000. There is also a slight change in the way you wake up the display when it goes to sleep if it is not docked.

                                The supplementary manual can be found here:

                                http://assets.fluke.com/manuals/233_____umeng0009.pdf

                                 

                                "Change #4

                                On page 13, replace the Battery Saver section with the following:

                                Battery Saver™(Sleep Mode) Units with S/N <224999999

                                The Meter powers-down (Sleep mode) if there is no function change, range change, or button push for

                                20 minutes. The lowest power drain occurs when the display module is docked with the Meter base. When

                                the display is docked and the Meter is in sleep mode or off, a power drain continues from intermittent

                                communication between the radios.

                                To wake up the Meter, push a button or turn the function switch.

                                To disable the Sleep mode, hold down the g button while turning the Meter on. The Sleep mode is always

                                disabled in the MIN MAX AVG mode.

                                To optimize battery life, it is recommended one battery be removed from the meter base and display for

                                extended periods of storage or intermittent use.

                                Battery Saver™(Sleep Mode) Units with S/N >225000000

                                The Meter powers-down (Sleep mode) if there is no function change, range change, or button push for

                                20 minutes.

                                To wake up the Meter, Remate the display or turn the function switch.

                                To disable the Sleep mode, hold down the g button while turning the Meter on. The Sleep mode is always

                                disabled in the MIN MAX AVG mode"

                                 

                                Now although I say Fluke tries hard, I think their customer surveys are not up to standard. Either that or they are not telling the customers the entire story such that they get what the customers wanted but at the expense of something greater; just like the case of Fluke 233 and some other product which I prefer not to bring it up.

                                Regardless, I hope you have some good results to share with us. Thanks.

                                    Regarding Fluke's customer service, I think you're spot on.

                                     

                                    They always offer to look into the issues, or take the product in for a check.

                                    Unfortunately the result usually brings little to nothing, and leaves the customers as they were.

                                     

                                    I posted earlier in this thread about battery issues with the Fluke 12x series scopemeters.

                                    Same story.

                                    After that I decided to sort the issue myself, and reported back to Fluke how to solve it.

                                    That's like half a year ago by now, but nothing has changed. They keep shipping a product they know is flawed, even though the fix is rather simple and surely easily implemetable.

                                    In this case the fix was to change the type of rechargeable batteries.

                                    Thanks for the heads-up on this.

                                     

                                    I have tried twice to contact Fluke's customer support concerning this issue. On neither occasion have I received a reply. I don't really fancy spending money on-hold on the phone or sending it off only for there to be 'no fault found', so I think I will just leave it in it's box on the shelf where it is now, and bring it out when I need a spare meter. The real fix would be to increase the current limiting resistor on the IR transmitter. It only has to work over a distance of 1cm or so when the unit is docked. Beyond that, it is classed as undocked and it switches to the RF link anyway.

                                     

                                    I get the feeling that this is a result of parent company Danaher's cost-cutting in action.

                                        Hey Everyone,

                                         

                                        Sorry that some of you have had problems with Fluke.  I for one think they are not only the best when it comes to test equipment.   The problem with the meter is not hardware.   It is firmware, the problem is fixed when they reprogram the meter to turn off.   That happens whit firmware revision 2.0   If you want to check your meter to see what revision you have, it's easy.

                                         

                                        "Hold down the "hold", turn meter to vdc. After a few seconds the display comes up with V1.00, V1.01 or V2.00. V2.00 has the battery fix."

                                         

                                        Let me know if I can be of help.

                                         

                                        Kind Regards,

                                            Hi Perry,

                                            Thanks for sharing the information on how to check firmware version.

                                             

                                            As for the problem definition, I do not know exactly what Fluke did but as you can see from the supplementary manual which I posted Sep 19 above, it appears that there is a difference in how you wake up the meter when it is undocked.

                                            For brand new units, S/N >22500000, you will not be able to wake the meter by just turning the function switch or pushing a button.

                                            For units with S/N <24999999, you can wake the unit by turning the function switch or push a button.

                                            I was not able to get any confirmation whether with the upgraded firmware for S/N <24999999, does the waking up behavior changed or does it remain the same as before; i.e. you can wake it up just by turning the function switch or pressing a button. Please note I am only referring to the case whereby the display is undocked.

                                             

                                            Now, if indeed there is a difference between S/N<2499999 and S/N>2500000 in the way the display wakes up when undocked, then I would be inclined to say there is indeed a hardware difference. I'm not saying it is a problem but I think there is a change in the hardware design.

                                      I have the Fluke 233 since 1.5 years, and i had to replace my batteries very often, and in Switzerland are Batteries very expensive (5 LR6 Cells for the device are around 12$). So i tried to use rechargeable batteries, and it works fine. So you can buy 10 rechargeable batteries and you run better and cheaper then buy normal cells.

                                        Hello Mike and everyone else who wrote about the problem with the Fluke 233 using up batteries.   I contacted Fluke and they also know about the issue.  It is underwarranty and they will either fix your meter or give you a new one and a free calibration as well.   Contact them, give them the serial number of the unit and they will tell you where to send it.   I sent my to Everett, WA.

                                         

                                        Also, I want to let everyone know.  I service and sell Fluke hand held test equipment.  I live in Elkhart, IN, USA.   Let me know if I can be of service

                                                Hi folks new here

                                                Fluke 23 for 28 years

                                                 

                                                 

                                                Thanks Perry,  I've also emailed Fluke re battery life.

                                                I have also gone to rechargables Nimh, will probably end up with the more expensive eneloops to minimise self discharge.

                                                 

                                                ====

                                                 

                                                A couple of points that would be good and may assist with the Fluke 233 mk2

                                                 

                                                1. If I walk out of range with the head in my pocket, say to the bathroom once back in range I have to reattach the head for it to read again. I havn't gotten around to figuring how long / far I have before the link is lost.

                                                 

                                                2. Wish it had the faster updating bar graph along the bottom of the display as I use this for checking speaker output from audio devices alot. This would save me having to carry two meters.

                                                 

                                                3. When the magnetic clip is attached the head is a hassle to remove and re fit. I've tried re configuring the strap velcro.

                                                 

                                                4. When I select auto off disabled, I'm unable to figure out how to also select backlight to stay on.

                                                 

                                                5. If longer battery life is not a easy option without it getting crazy expensive then a inductive charge mat / holster would be ok for me.

                                                        As a plug and socket with dust cap to eventually fall off then foul up or my screwdriver jiggle into and short out as my meter can get dirty.

                                                        e.g like my Braun toothbrush would be just fine.

                                                 

                                                Still a great product as it saves me a man, I'm still feeling the lucky vibe

                                                 

                                                Regards

                                                    Hey Guys,

                                                     

                                                    I got to looking back over some emails and found the one that talks about the battery drain issue.

                                                    If you have a meter that has a serial number below 138xxxxx  it will have the problem.  The fix

                                                    came after that.

                                                     

                                                    Let me know if I help.

                                                     

                                                    Best Regards,

                                                        Any idea what the meter's improvement is after 138x ?

                                                            I am unsure what the modification is, but I do know it fixes the problem with the batteries draining prematurely.   If your meter is pre 138x, I would highly recommend sending in to Fluke.  It should be covered under warranty.

                                                                Is this the same for a repaired / replaced meter ?

                                                                Why would both batteries fail at the same time as per above photo, 

                                                                as I would have expected the rx would use less power ? or do both consume battery capacity at exactly same average rate hence 3 and 2 cells ?

                                                                Is this the same post 138xx meter ?

                                                                If I hold down yellow function button while turning on,  around 2 oclock I get rf and ir screens, any ideas what this is telling me ?

                                                                        If you know a specific contact email which can be useful in this case please let me know.

                                                                          Thanks for sharing with us that there is a software fix for the battery drain issue.

                                                                          I am still not quite clear after reading your message below what fluke has done to solve this issue.

                                                                          You mentioned that "Also, the mode for 138xxx and below turns the meter all the way off after the battery get to low." Should it be 138xxx and above turns the meter all the way off after the battery get to low?

                                                                          Is this specifically the fix?

                                                                           

                                                                          Also, I'm confused by the following "The lowest power drain occurs when the display module is docked with the Meter base. When the display is docked and the Meter is in sleep mode or off, a power drain continues from intermittent communication between the radios."

                                                                          Is Fluke trying to tell us to enable or disable sleep mode in order to not let the batteries drain?

                                                                           

                                                                          Finally and if you don't mind, I'm assuming you already have a unit with the fix. How did you estimate the battery life to be 400 hours? That's presumably several years worth of battery life. This is a sincere question and I am not challenging you.

                                                                          Thanks for your help.

                                                                        Mike's original post describes the battery life of mine exactly.

                                                                        I have sent several emails to Fluke and they have not responded at all.

                                                                         

                                                                        From what I have read so far about why, I think it's amazing that this unit's mechanical dial -when switched to the "OFF" position, does not actually disengage it's power supply and switch the unit off.

                                                                    Just had my meter returned and updated to version 2. The technician said that hardware updates may be involved. The current draw has decreased as follows:

                                                                     

                                                                    Base unit: 0.086mA
                                                                    Display unit: 0.11mA

                                                                     

                                                                    This is an order of magnitude less than the original so for a 3AH battery the lifetime is now over 3 years in theory. This is quite significant.

                                                                     

                                                                    Now the specification for the battery life can be believed as the operating battery life should not be significantly diminished if the battery is off.

                                                                     

                                                                    I think that the original meter (prior to version 2) made the specification for the battery life entirely incorrect: the batteries never lasted 400 hour over a reasonable battery life of 3 years, let alone 1 year. This is because it is generally understood that battery life is not significantly reduced when it is off, and there is nothing in the specification that says otherwise. It seems that Fluke are happy to fix this problem if it is within the warranty period otherwise. In Australia failure to fix the problem and the false specification for the original version easily violates the Competition and Consumer Act.

                                                                     

                                                                    http://www.fluke.com/fluke/auen/Digital-multimeter/Fluke-233.htm?PID=56054

                                                                     

                                                                    I am really quite thankful to Fluke for organising to get mine fixed. Before this I was considering getting rechargable batteries.
