Hello

Any person knows where I can find the electrical schematic of the multimeter
Meterman 37XR, or any information?
Maybe the serie 30xr, 33xr, 34xr, 38xr they will be seemed

It is for to attempt to repair it.
I connected it to more than 1000v, (it was not knowing that there was more than
1000v)
and now indicates low impedance between the test leads, 2.400 ohms.
I know maybe the failure is only in the input stage.

The low resistance across the test leads may indicate that there is a
protection diode or two across the probes, which have failed to a short
circuit.
