Hello scott!
Just did some long term logging of 10MR. Don't see the same error you discuss, is there any specific things I missed with my tests?
Test 1: Simply connected 10M resistor to the multimeter and logged for an hour.
Test 2: Placed multimeter in a thermal chamber starting at 26.6 degrees and raised it to 35.6. The 121GW measured a 10M resistor that was outside the thermal chamber (so it was unaffected by rising temperature or humidity), logging for an hour.
NOTE: There are some glitches in my logging, thats just when I bumped the leads with my computer mouse, try not to move wires when measuring such high impedances.
The next test starts at 26.6 and raises to 35.6. These were logged using the windows app over bluetooth. At about 2000 I left the room for lunch and the erroneous readings stopped entirely, again high impedance readings are very sensitive.
Are you able to show something similar? I recommend using the Windows App for this is as it will make saving and posting the data a little easier.
Nope, no difference. I didn’t log the results, I just watched it change.
I’ll have to find my wondws laptop and install the software.
Speaking of apps, do you know what happened to the iOS app for Apple devices? I had it downloaded and it controls thing like ranges, hold, but doesn’t display any numbers. Then I realized it was removed from the iOS App Store, do you know when we can expect this to be returned?
I also took into the consideration based off Dave’s video showing a grounded ESD mat affecting mV readings and moved it to another room that is latterly empty. Still the same results.
I’ll try to log it if I find the computer, It might just be my meter?
Thanks for checking and running the tests,
Scott
