I find it a quite neat interpretation of the original "Komponententester" by Karl-Heinz Kübbeler.

Tooling yourself a nice (handheld) case isn't normally achieved at $20, so the price looks good to me.
I already showed an new firmware which is suitable for a clone in this topic.
BSideESR02 has no protection of measuring ports! If you have connected the capacity which had a charge, then the processor it is necessary to replace with new.

I have collected an firmware only for the Karl-Heinz 1.13k version. I think that there are no obstacles to use the version 1.33m Markus.
The Chinese firmware of BSideESR02 is based on the version 1.11k Karl-Heinz!

Sorry
Is BSideESR02 is ONE chineese version housed in fabric-made enclosure?
Yes, I always discharge capacitors before testing. But I wasn't testing capacitors last time it was used - I was sorting thru a box of pulled transistors, separating FETs from BPs. It's quicker than looking up the numbers So this failure is unexpected.

They are identical on an firmware and a hardware stuffing.Yes, I always discharge capacitors before testing.

The scheme is rather simple in understanding if to study a detailed manual from dear Karl-Heinz.
Powered mine up a couple days ago, it only shows a blank white screen after pushing the Test buttons to null the leads. I was fairly happy with it up till then. Probably not worth trying to repair... sigh.
