8 MEASURING VOLTAGE
Programming the measuring voltage of the system.
The values programmed here always refer to the voltage at the clamps of the
device !
The voltage is selected via the é /ê keys. Save and continue with ENTER.
9 V - CONVERTER RATIO
When a measuring-voltage converter (e.g. for HV-measurement) is used, its
conversion ratio should be programmed here.
(Input of prim.voltage is here, sec. voltage is automatically from item 8)
Selection via the é /ê keys. Save and continue with ENTER.

10 CONNECTING TIME
This refers to the time between connecting the capacitors to increase the
momentary network capacitance. It should be noted that in practical operation the
real connection time is affected by the discharge time (locking time).

Default setting:
Selection is performed via the é /ê keys. Continue with ENTER
11 DISCONNECTING TIME
This refers to the time between disconnecting the capacitors to reduce the
momentary network capacitance.
Setting range:
Default setting:
Selection is performed via the é /ê keys. Continue with ENTER
12 DISCHARGE TIME
This is the time for which an individual output is blocked between connecting and
disconnecting. This blocking time has priority over connecting and disconnecting
times. It depends on the capacitor discharge rating and thus is specified by the
compensation network. The discharge time of a conventional network without
additional fast-discharge resistors or chokes should be set to no less than 40
seconds. For setting of a second discharge time compare 'Expert Mode1' point 12
