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 m
easurements.
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 wi
thout 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 instrum
ent off after a period of
approximately 10 minutes. The Auto power off mode can
only be cancelled by switching the instrument on again.
