Typical Input
Impedance:
10MΩ//<1000pF, except for Vdc plus Vac measurement when the
1MΩ ac attenuator is in parallel with the 10MΩ dc attenuator.
Maximum Input:
1kV DC or AC peak, any range.
NMR:
>60dB at 50/60Hz.
1kΩ 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.
