Hi,
LCR measuring tweezers, to which the greatest things are attributed, as the sole miracle tool that makes other LCR superfluous, where some people never tire of bringing them into play in every purchase advice....something like that makes me curious in principle.

So I bought one from Aliexpress and it should arrive next week.
In addition to an incoming inspection in terms of appearance and manufacturing quality, the main component will of course be measurements.
I have thought of the following steps:
- Measurements on the DMM Plus Check reference, more precisely on its LCR option.
- Comparative measurements with the following devices:
Mastech LCR tweezers
ET4410 Benchtop LCR Meter
ET4510 Benchtop LCR Meter
Sourcetronic ST2830 Benchtop LCR Meter, calibrated
Agilent U1733C Handheld LCR Meter, calibrated.
GWInstek Milli-Ohm Meter, calibrated.
- Comparison measurements on components that are already integrated in a circuit.
- Comparison measurements cold start/ after a warm-up time.
The latter because it was said that with other devices you have to wait until they meet the tolerance.
I maintain that it doesn't matter.

We'll see.
Furthermore, an attempt to see what maximum component size can still be measured mechanically without using aids such as wire extensions, which of course distort the result.
And one more thing, measurements on coils with a core, if their size allows it.
This could be interesting insofar as the measuring voltage of the ST42 is rather low.
I'm curious to see how it performs.
Why am I opening this thread now?
To collect further ideas, if you think of anything else, post it here.
Next post will follow when the ST42 has arrived.
