Hi Everyone,
Recently, I got myself an Extech EX430.
After using for a month, I ran into some problem today when using it to measure uA current.
I was measuring for few hours and it was fine showing some current like 22 uA. Then suddenly it only shows OL.
I opened up the meter and checked the fuse, both are okay.
I look for any possible burn components, but couldn't find any really.
I thought of getting some opinions before sending them for warranty.
Thank you.
