Loop impedance, PSC/PFC and RCD testing functions have the following features:
Wiring check
Three Wiring symbols indicate if the wiring of the circuit under
test is correct.
Over temperature
protection
Detects overheating of the internal resistor (used for LOOP and
PSC/PFC tests) and of the current control MOS FET (used for
RCD tests) displaying a warning symbol and automatically
halting further measurements.
Phase angle
selector
The test can be selected from either the positive (0°) or from the
negative (180°) half cycle of voltage. This selector is used in the
RCD mode to obtain the maximum trip time of an RCD for the
test selected.
UL value selector
Select UL (limit of contact voltage) 25V or 50V. Where Uc
(contact voltage) exceeds UL value at RCD testing, “Uc > UL”
will be displayed without starting the measurement.
ALL testing functions have the following
Touch Pad
Gives an alert, when touching the Touch Pad, while the PE terminal
is connected to Line by mistake.
Memory Function
Save the measured data in the internal memory.
The data can be edited on a PC by using Communication Adapter
Model8212USB and PC Software “KEW Report”.
Auto power off
Automatically switches the instrument off after a period of
approximately 10 minutes. The Auto power off mode can only be
cancelled by switching the instrument on again.
