54 100,000 cts digital multimeters
Technical characteristics of the MTX 3292, MTX 3293 (continued)
Resistance
Ohmmeter
In this setting, the user can measure a resistance.
Particular reference conditions:
The (+COM) input must not have been overloaded following the accidental application of a
voltage to the input terminals with the switch set to Ω or T°.
If this happens, the return to normal may take about ten minutes.

For measurements
above 5M  , a shielded
lead is recommended.
For a 2-wire link, use
very short wires
(<25cm) and twist them
together.

“Active” protection by PTC thermistor
Measurement voltage: approx. 1.2V
Maximum open-circuit voltage: 3.5V typ.
In the 100M  range, in order to avoid the influence of the mains and guarantee the
stated specifications, it is best to disconnect the multimeter from the Wall Plug.
