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
