Smart SMD tester MS8911.

I made a more advanced device for zeroing. At the same time, it can be used as a stand for tweezers.

Is that something you have to do before using them?

Short Circuit Zeroing: First, select the test frequency that you want to zero. Insert a short-circuit piece into the test socket,
whether using SMD test tweezers or clamps. Short-press to enter zeroing mode. The instrument will automatically
measure and execute the corresponding short circuit zeroing after identification.
This is written in the manual. You decide for yourself whether to do zeroing or not. For example, you shorted the probes 1-3 times and you have N milliohms on the display. You decide whether this error will affect the measurement results or not. If not, then there is no need to zero. If you measure low-resistance resistances and picofarads, then you must zero. In addition, I have the corresponding components soldered onto the test boards and I immediately check the zeroing result.
