Hi Group, can someone help please? I was working on a Hisense 40" LED TV, T esting 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 a ll tested -0.00 I know that is not a correct reading, when initially turnin g on the meter it supposed to read OL now reads .729... so i tested the cap s with a DMM and found three bad caps. can this meter be fixed?? any sugges tions 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.

did not work, still reading -0.00...
I expect that it is toast, then.

Look at it as an expensive lesson learned the hard way.

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.
