LQ-9101 LCR meter manual?
« on: June 11, 2018, 03:04:47 am »
I bought one of these LCR meters off ebay, from china, but it came without a manual. The specs of many  ebay vendors invariably say "see the user manual".
At power up the LCD says:

   Copyright 2015, All rights reserved, LQ, Co., Std.

I tried emailing the seller and sales@lq-china.com but had no response, and they do not list it on their website as a product.

It comes with 4 buttons on the front.
  • changes frequency 0, 100, 120, 1000, 10000Hz
  • no idea
  • changes RMS voltage of test signal from 0.1, 0.3, 0.6V
  • changes between 4 display modes

I was wondering if maybe the second button was some kind of test lead compensation/calibration/zero function, but it doesn't seem to change much at all.

In one mode it displays resistance and phase angle. Having never used one before, is the resistance likely to be just the real part of the complex impedance, or would it be the magnitude, sqrt(Re^2+Im^2)?

Thanks

Chinese documentation https://pan.baidu.com/s/1gf6c1rX#list/path=%2F&parentPath=%2F
I can't check it cause it require to install their client for downloading.

Short pieces, high value, small period, huge amount, long delay.

Wow! Awesome!
I was able to download  a Chinese language version of the manual and run it through Google docs translate  to get something useful!
Thank you very much!

(edit:  cn-pdf -> google doc -> MS docx -> en-pdf attached - functional but rough)
