Sencore LC102 & LC103 Capacitor & Inductor Analyzer

That zero issue fix on Antique Radio was a bit off in technique.
I first cut into the top of relay cover as shown in pics.
Yet afterwards, I found I could simply squeeze rectangular cover and it unlocked and whole cover came off without having cut on top that then needed to be fixed.

I will try a few other cables soon.

With the LC53, LC75, LC101 (units that I've owned), RG62 cables were needed to be able to zero out the meter.
With my LC103, I have no trouble with open and close compensation with any of the cables I normally use.  I use the Sencore 39G219, Fluke tweezers, mini 7" BNC to clip hook leads, and sometimes a set of needle probes for in-circuit tests.

Per the LC103 Manual for Value Beyond Zeroing Limit...

An open (greater than 20kohms) or shorted (less than 1 ohm) test lead will cause the display to show "OPEN" or "SHORT"
Possible Causes:
1. The capacitance at the TEST LEAD input is greater than 1800pF
2. The inductance at the TEST LEAD input is greater than 18uH
3. The resistance at the TEST LEAD input is greater than 5 ohms

Replaced L1 & L9, no improvement  :-BROKE

Will try to replaced the 4011 & 4066 in the ESR circuitry.

Hello;

I am looking for a new or used LC102 membrane keyboard to repair the one I have. One of the "button" is worn straight through....

Thanks!

Every once in a while, they show up on ebay USA but right now I do not see one.
You probably have to have some patience.
