My Greenlee digital multimeter reads line voltage about twice what it is. What do I need to look for?
Is it possible you are seeing some variation on peak-to-peek voltage vs AC RMS which is more commonly used? Are you positive you were using the proper AC range rather than a DC range? Instead of double it should be more like 1.414 x the actual RMS voltage. If you were using the right range (AC) then your meter probably has an internal diode out. Because of isolation and other safety features in a VOM, factory repair may be preferable to possibly having a less safety aware tech repairing it.
Do you know what kind of meter abuse caused this damage?
Instrument repair has always been a more specialized and demanding arena of electronic repair.
If it's a $25 meter it could easily be more expensive to repair
than to replace with a new one.
This is all general information because you did not specify
which model of Greenlee multimeter you have.
It's easy to blow a VOM by putting it across a circuit when it's
set to the wrong range.
