Multimeter Data Logging Software for Windows, Linux, Mac and Solaris

[mpf]

I have written a little Java program to log the data from my QM1358. It should also work for Digitech QM1537, Digitek DT-9062, Digitek INO2513, Digitech QM1462, PeakTech 3330, Tenma 72-7745, Uni-Trend UT30A, Uni-Trend UT30E, Uni-Trend UT60E, Voltcraft VC 820 and Voltcraft VC 840 multimeters.

It uses the RXTX (http://rxtx.qbang.org) native serial libraries which are available for Windows, Linux, Mac and Solaris. I have prepared pre-packaged zip files for Windows installs.

You can download the program from http://www.forward.com.au/DataLoggingSoftware/MultimeterDataLoggingSoftware.html

That page also covers other software packages for data logging from other meters.

Here is plot I produced using the Multimeter Data logging software and OpenOffice Calc. It is of Battery Temperature while being charged by NiMH battery charger I made which uses delta T cut off. i.e. rise >1.5degC / min

That's really cool to have a delta T termination!
How do you ensure a solid/consistent thermal contact?

My battery pack is three lots of 4 batteries stacked. The NTC resistor is slipped inside the stack for and so is completely surrounded by the batteries. The whole battery pack and charge are inside the torch. For photos
