I was attempting to check the a winding on a SMPT. The board has recently been powered on, but it was unplugged and I drained the filter cap. When connecting the probes I heard a tiny spark of static and the meter turned off and will not come back on. Any ideas?

Re: I just broke my Blue Ring Tester. Can you help?
I would first check if the battery is good.
If it has protection devices on the input, those could have shorted from the spike, and drained the battery. Check the battery in circuit, with a DMM.
Otherwise, I would replace the counter IC and any op-amps.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Battery is good. I just did a search (should have done that first) and see that it is most likely IC1. I will swap it out and see what happens.Comment

Confirmed it was IC1. Is there any way to add protection without effecting accuracy?Comment

A 10V bidirectional TVS across the test terminals should do.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!
