6.5.1 Voltage measurement
Voltage: ±60 V ... ±5 V with divider
Voltage: ±2 V ... ±50 mV without divider
An internal pre-divider is in effect in the voltage ranges ±60 V to ±5 V. In this case, the differential input
impedance is 1 M , in all other ranges 10 M . If the device is de-activated, the impedance is always 1
M .
The inputs are DC-coupled. The differential response is achieved by means of the isolated circuiting.

6.5.1.1 Voltage measurement with zero balancing
In the measurement mode voltage measurement with zero balancing, it is possible to balance the
measured value.
This is accomplished for all selected channels either by means of the channel menu command Balance in
the measurement window or on the Balance page accessed via the module node Isolated amplifier.
Balancing using the Measure dialog
