I'm road testing the  Keithley Bench Digital Multimeter DMM6500. I proposed in my application to focus my review on instrument automation. In this post I review Keithley Communicator, an application to directly send TSP and SCPI commands to the meter.   Keithley Communicator  This utility is great in its simplicity. It's a little app where you can type commands and push them to the DMM6500. The app has an output window to print any info returned by the meter. This is idea ...
I'm road testing the  Keithley Bench Digital Multimeter DMM6500. In this post, I investigate how to use the external trigger to start a measurement. In this post, everything is configured and executed in LabVIEW. In the previous post I used the front panel.     Goal: I want to measure the voltage on a microcontroller GPIO pin just after it is set to high. Check out the last post for the details.   Set Up the External Trigger with LabVIEW  I'm using the SCPI :TRI ...
I'm road testing the  Keithley Bench Digital Multimeter DMM6500. In this post, I investigate how to use the external trigger to start a measurement. In this post, the setup is manual. In the next post I'll use LabVIEW to automate the process.     Goal: I want to measure the voltage on a microcontroller GPIO pin just after it is set to high.   External Trigger  The DMM6500 has an external trigger input at the rear of the instrument.     It's a BNC con ...
I'm road testing the  Keithley Bench Digital Multimeter DMM6500. In this blog, I presents a script that measures a microcontoller power consumption using an EEVblog µCurrent. Knowing the amp hours your application consumes, helps to predict battery life. Battery capacity is given in this unit. With modern switching converters, you can squeeze almost all capacity out of a battery. Knowing how much runtime all that capacity gives you is useful.   Why a µCurrent?  ...
I'm road testing the  Keithley Bench Digital Multimeter DMM6500. In this blog, I verify the performance of an EEVBlog µCurrent via LabVIEW. Note: this is not a real validation of the µCurrent . This is a showcase on how a DMM6500 can be used in such an exercise. For practical reasons I am using an oscilloscope to measure the DC output of the µCurrent. That is not a precision device. And there's way too much noise in my lab to make a meaningful measurement that way. ...
I'm road testing the  Keithley Bench Digital Multimeter DMM6500. In this blog, I verify the performance of an EEVBlog µCurrent; from the DMM6500 frontpanel controls..     The µCurrent is a test instrument that translates current to volt. You can think of it as a shunt resistor with an amplifier. It's specifically designed to be used for low current measurements. In this blog, I want to compare its measurements with the DMM6500, in mA range. Not for a specific ...
Start-up company, Spryng has released its latest device, Spryng, to help with those tired, achy legs after a workout. (Image Credit: Spryng)   Exercise buffs, hikers, gamers, travelers, partiers and people who have sat at the desk for too long all have one thing in common ─ tired, achy legs. Soreness, acid build up, and blood pooling in the lower legs can cause muscle weakness and pain. Spryng, a start-up company has released a product under the same name, gives relief to wearers and allow ...
I'm road testing the  Keithley Bench Digital Multimeter DMM6500. The instrument can run apps, and you can roll your own (what a great time do be alive ). In this blog, I'll show how you can show images on the display.     Why, Jan?  Apps make it possible to change how the instrument operates. It can give a completely different look and feel. When you are using this for prescribed situations, or in a fixed setup, this can help to have repeatable results.   You ca ...
IBM’s fingernail sensor on the thumb of a test subject. (Image via IBM)   A group of scientists are focused on predicting the evolution of neurodegenerative diseases so that patients could receive treatments tailored to their needs. To achieve that these scientists are turning to wearable technology. It is not surprising given the progress of science and technology in recent years, especially the development of wearable technology for medical purposes. Even though there is a lot happ ...
I'm road testing the  Keithley Bench Digital Multimeter DMM6500. In this post, I test the script to measure DC power. The setup uses the input to measure output voltage of a Buck converter, and measures current via the sense input and a shunt.   Measure DC Power with the DMM6500  The DMM6500 has no power measure option by default. But the instrument can measure 2 voltages at the same time, when in Voltage Rate mode. In that mode, it will measure the voltage over the inputs ...
I'm road testing the  Keithley Bench Digital Multimeter DMM6500. I proposed in my application to focus my review on instrument automation. So let's get straight into that. In this post I review the remote control options and other automation functions.   Programmable Instrument  The DMM6500 positions itself as both a bench meter and an instrument that fits in a rack for automated test setups. I'm focusing on the latter in this post.   Some of the software options tha ...
Guanyu Technology’s ‘intelligent uniforms’ feature a pair of chips in the shoulders to keep track of students locations. (Image credit: Guanyu Technology via ABC)   More than ten schools in China’s Guizhou Province and Guangxi Zhuang Autonomous Region have adopted intelligent uniforms for their students in an effort to keep tabs on their location- when they enter and exit school grounds. School officials record when they arrive and depart, and automatically transmit ...
