Use the 



 keys to choose the preset step type of test:

Step function 1: 50 to 500V
Step function 2: 100 to 1.000V
Step function 3: 500 to 5.000V

The values of the voltages at the beginning and end of a step, the number of steps, and the duration of each step can be 
programmed using the CONFIG key (see §4.3).

3.3.6. CoNNECtIoN

Depending on the measurements to be made, there are three ways of connecting the instrument.

In all cases, disconnect the device to be tested from mains.

 

„

Low insulation

Connect the red high-voltage lead between earth and the + terminal of the instrument. Connect the black high-voltage lead 
between one phase of the motor and the - terminal of the instrument.
