Hello

The low resistance is 2,4Kohms, yes, maybe it is a diodes or a resistors, but
have a lot, and they are SMD, but there is not a "short short" circuit,
when I place the rotary swich at Ohms, the display indicate 2,4Kohms,
and in the others: Volt, Capacitance, etc. the display shows a value altered
when I attempt to test a voltage, capacitance, etc.
All the ranges are protected but this metter not have a protection
for over than 1000v.

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.
