Excellent testing methodology! It’s easy to overlook meter burden and physical node differences during measurement, so using the dual-point fixture to verify the baseline first was a great approach. That LED test really proved the value of the FNB58 for low-current detection.

JC after playing with the programming did you find anything that is useful?

I'm a bit of a cynic when it comes to automating some testing. I fail to see the benefit on a VOM multimeter.

The TSP Editor has moved from an Eclipse based IDE to a VSCode plugin. Version 1.5 is released, and that works good for me

You can manage the instrument (e.g. upgrade firmware), save and restore settings, execute automation scripts

... and in this version, the script debugger works:

Hi,

It might be good to split up the project, because the chances of someone owning those same precise two instruments, _and_ requiring a component inventory system might be low. It likely needs configurability (or is it planned to be open source), so that users can configure different instruments.
