Digital Multimeter Brymen 896s Issue

[barathi]

Hey Guys,

I've been having a couple of issues with my DMM recently and I've no clue on how to go about fixing it.

1) The DMM doesn't read AC voltages anymore. All I have is OL

2) The temperatures readings are stuck at ~330˚C on both T1 & T2

I looked at the internals and there is no obvious sign of damage. I've not connected my DMM to a high voltage source on a wrong mode (to the best of my knowledge). The fuses are good. The battery is new and in perfect shape.

Being a complete noob, I'm clueless as to what my next steps of troubleshooting should be.

Could you guys help me with the next steps?

you need to seperate the boards, but first email Bryman.

I wrote to Brymen about a month back. No response from them

I will separate the boards and look for obvious signs. Thanks for your inputs.

Extech are not helpful either. And I used my work email adress, and no reply...

There should be a rectifier (diodes) at the imput for the AC voltage, and also one or two capacitors and resistors. Maybe some of them are blown.
