content: I've been trying to find an affordable data logging meter for DC circuits. (Amps, voltage, and watts) Would like to record values over time so they can be plotted.Any suggestions?The Digitek DT-4000ZC / TekPower TP4000ZC Data Logging Multimeter mentioned in a video is no longer being sold and the link to the software is dead. I saw a link to an open source project but the software doesn't work beyond Windows XP.Thanks

content: A bit of a curve ball: How about the new Keysight E36300 series bench power supplies? These can do logging as well and the biggest advantage is that there are no problems with burden voltage when measuring the current.

content: Quote from: DougSpindler on November 26, 2017, 07:14:22 pmFor that you'd need a different solution. I'd go for two bench DMMs and write some software to dump the results into a CSV file.

content: Quote from: nctnico on November 26, 2017, 07:25:16 pmThat's exactly what I'm looking for. The meters in an EEVlog video and software are not available any more.I'd like something like this. Arduino Data Logger with Direct Input to Excelhttps://youtu.be/AgJegJ30Pj4

content: Quote from: mtdoc on November 26, 2017, 07:33:34 pmI like it. Cost is around $125 in the US.Okay, just read through the specs..... This is great.I'm looking at the specs.Do you have one?https://moosh.im/mooshimeter/specs/Can I measure AC and DC current up to 10A?If the phone/tablet is out of range does it save to the SD card so I can download latter?Buying one now.

content: I'm looking for a similar device as DougSpindler. I have bought at Mooshimeter but there is a feature I miss. I want to see the data (line graph) while logging. The problem with Mooshimeter is that I have to download the data as csv, insert it to a spread sheet and generate a line graph. The android software for Mooshimeter can show a line graph with data streamed to phone but not with data from SD.Can I walk up to a logging 121gw an pretty easy see the data (as line graph) from say the last two days?

content: The bottom of the range GW Instek GDM-8341 without the GPIB or USB datalogging port on the front can still send measurements to Excel (called the Excel add-in) via the remote control USB port on the back. Amazon UK have been selling them off cheap, I paid £219. It's a nice bench DMM, even if Amazon showed a pic of one with the GPIB port
