Keypad
Is there an obvious reason why the keypad (buttons) would stop working. If I unplug it I can turn it on with the on/off button but then that button will no longer work nor any of the others. The probes themselves seem to work fine and there is a read out but the buttons/keypad themselves seem to have stopped working all together. If not an obvious reason how about an easy fix.

I have a document that might help you to get the keypad working again. There are no longer spare parts for this unit, so if that doesn't work the meter will have to be replaced. Please email me at uslabtechsupport@mt.com, attn: Nancy and request the document.
