Notes!
•
If RCD trips during Contact voltage measurement (some fault or leakage current
is probably already flowing to ground),
rcd
mark will start to blink.
•
Nominal differential current, set in this function, will be offered in other RCD
functions (Contact Voltage, Trip-out Time and Auto RCD test)!
•
Limit Contact Voltage Ulim can be set in
Contact voltage
function only!
•
For safety reason will Trip-Out Current measurement be carried out only, if
Contact voltage at nominal differential current is lower than set limit value!
•
Current, flowing to PE protective conductor, caused by faulty appliances or
capacitive connection between L and PE terminals, will influence on test result.
Disconnect such appliances before measurement is started!
•
Specified accuracy of tested parameters is valid only, if earthing system
connected to PE terminal is free of interfering voltages!
•
bat
message, displayed during or after finishing the measurement means
batteries are too weak to guarantee correct result. Replace the batteries.
