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.

Ah I read it as 2.400 ohms, any road up, that`s where I would start looking.
