Technical characteristics of the MTX 3290 (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.
Protection: 850Vpk
