hello
i have a problem with my multimeter
the multimeter not reading any thing and the display -1 only and not reading anything
i check the fuse and replaced it
and still this problem
please help me to solve this problem
Thanks

 

If a new battery doesn't fix it and none of the ranges work then unless it is an expensive model bin it and buy a new one. They are available very cheaply these days.

but i wanna to fix it
this a new multimeter i get it from three days ago
you hve an idea to fix this common problem ?

 

this a new multimeter i get it from three days ago

In that case take it back and get a new one under warranty.
Without a schematic it will be difficult to fix and possibly even more difficult to get replacement parts.

 

i try to get it back but refused

Don't buy from that vendor again. If it was a new meter then the vendor should take it back. I hope you did not pay too much.

 

this is the problem not reading any thing just this -1 only

 

You did try a new battery?

 

yeah

 

i think this problem from using a circuit to get 9 volt from it

 

Was it working when you first got it? What did you do just before it quit working?

 

Yes it was work perfect
I make a circuit to use it instead of the battery from 220 ac voltage to 9 volt dc
I used a transformer and bridge and capacitor and i still work on this circuit instead of battery of the multimeter then it get this -

 

Does it work if you put the battery back in instead?

If not, then maybe your device gave you more than 9v output and it broke your meter. For the future, be sure your device has a way to limit output voltage. Maybe when there was no load it built up more voltage than you expected.

 

sure i try to use battery after this problem and this not fix this problem
i think found an problem in the resistor of the multimeter
