Setting The System Leakage Capacitance Or Measurement Speed - Bender ISOMETER isoPV1685RTU Manual

7.3 Setting the system leakage capacitance or measurement speed

The switch 6 of the DIP switch SS8103 is used to set the profile considering the maximum
system leakage capacitance C
The measurement speed can be changed using switch 7.
The switches 6 and 7 of the DIP switch SS8103 are used to switch the maximum system
leakage capacitance C
set to "Slow" in case of frequently occurring fault alarms caused by transients in the system.
In the slow mode, the measurement time doubles. Segment 8 is reserved.
DIP switch SS8103, segment 6:
OFF = 500 µF = C
ON = 2000 µF = C
DIP switch SS8103, segment 7:
OFF = Fast
ON = Slow

These settings may only be changed when the PV voltage is switched
off.
When the maximum system leakage capacitance C
2000μF the upper limit of measuring range for the insulation
resistance decreases from 1MΩ to 50kΩ. Therefore, check also the
