MESR-100 METER SHORTED
Hi Group, can someone help please? I was working on a Hisense 40" LED TV, Testing the CAPS in circuit with the power on(plugged in), with the MESR-100 v2.3 meter and accidentally crossed the leads on the meter testing a cap, on the power supply and as far as i know, I only blew the fuse on the board, I removed 8 caps from the board and tested them with the meter and they all tested -0.00 I know that is not a correct reading, when initially turning on the meter it supposed to read OL now reads .729... so i tested the caps with a DMM and found three bad caps. can this meter be fixed?? any suggestions on this matter will be taken seriously, Thanks..

Usual rebooting stuff first: Remove the battery, hold down the on/off switch for 30 seconds. Then try again. Please report back.

I expect that it is toast, then.

If you buy another ESR meter without voltage protection, try putting 2 power diodes in parallel across the input. Tie the cathode of one to the anode of the other. It has protected my Bob Parker meter for years. |
