ACCURACY
Accuracies apply for 1 year 19°C to 25°C. Temperature coefficient outside these limits is <0.1 x
quoted range accuracy per °C.

Typical Input
Impedance:
10M://<1000pF, except for Vdc plus Vac measurement when the
1M: ac attenuator is in parallel with the 10M: dc attenuator.
Maximum Input: 1kV DC or AC peak, any range.
NMR: >60dB at 50/60Hz.
1k: Unbalanced CMR:
>90dB at DC/50Hz/60Hz.
Recommended maximum peak AC plus DC voltage while measuring DC voltage
These values only apply when the DC component does not exceed the range maximum and the
analogue 50/60Hz rejection filter is enabled.
