Tenma 72-960 LCR meter calibration?
« on: July 05, 2024, 07:29:23 pm »
Hi,
We have a Tenma 72-960.
Do you know how to calibrate it for inductance measurement?, ie, the open and short cal?

That is described in the manual. Look for the user manual
There are small lies, big lies and then there is what is on the screen of your oscilloscope.

Thanks for the B&K 878 tip-off

...ill take a closer look , not now, the internet at M25 Cobham Services is hideously slow.

Thanks, so it seems that sometimes it diplays "opn", and then you have to open the test leads and then press "cal"...then sometimes it displays "srt", and you then short the test leads and press cal.

But it never seems to offer me "opn" or "srt".

How do we get it to offer this?
