Checking the DC Measurement Inputs
Test equipment:
DC Power Supply NGSM 32/10 (see Chapter “Test Equipment“, Item 10)
Multimeter URE3 (see Chapter “Test Equipment“, Item11)
DC cable (see Chapter “Test Equipment“, Item12)
Test setup:
Connect the Power Supply to the Input DC MEAS 1V (DC MEAS 10V) of
the ZVA using the DC cable

For DC Meas 1 V:
- [ Meas : More : DC Inputs : DC Meas 1 V]
- [ Format : Real]
- [ Scale : Scale/Div : .25 x1]
- [ Marker ]
For DC Meas 10 V:
- [ Meas : More : DC Inputs : DC Meas 10 V]
- [ Format : Real]
- [ Scale : Scale/Div : 2.5 x1]
- [ Marker ]
Measurement:
Set Power Supply to DC values U
