9.1 (2.2) Current
Set the maximum locating current on the ISOMETER®. You can find the device-specific
maximum locating currents in the table below.
Risk of malfunctions due to excessive locating current on sensitive
system parts!
The locating current flowing between the IT system and earth can cause
controller faults in sensitive parts of the system, such as the PLC or relay.
Ensure that the level of the locating current is compatible with the system
to be monitored.
