These are loop resistances, therefore the resistance under test
must be subtracted from these figures. If the ‘Rc’ indicator is not
showing, the maximum error will not exceed 2%.
Max. Potential Spike Resistance: An additional error (typically 1%) will be introduced by a Potential
spike resistance of 75 kΩ. If the ‘
Rp’ indicator is not showing, the
maximum error will not exceed 2%.
Max. Output Voltage: 50 V
Display: 3
