Wiring check Three LEDs indicate if the wiring of the circuit
under test is correct.
Over temperature Detects overheating of the internal resistor
protection (used for Loop tests) and of the current control
MOS-FET (used for RCD and Uc tests)
displaying a warning symbol "
" and
automatically halting further measurements.
15mA Loop Loop impedance 2000Ω range measurement
measurement is carried out with low test current (15mA).
The current will not cause tripping out involved
RCD even the one with the lowest nominal
differential current (30mA).
DC Test Allows testing of RCDs which are sensitive to
DC fault currents.
Phase angle selector The test can selected from either the positive
(0° ) or from the negative (180° ) half-cycle of
voltage.This will prevent tripping of some
polarized RCDs when Loop testing(20Ω range
only) and may give a more accurate reading
when testing RCDs.
UL(touch voltage limit) Select UL 25V or 50V with pressing the UL
value change and Uc value select switch. Where Uc value exceeds
monitoring UL, "UcH v" will be displayed without starting
the RCD test.
And at Uc range, can monitor the Uc value.
Other features:-
Auto data hold Holds the displayed reading until pressed or
rotated any switches after the test is complete.
Auto power off Automatically switches the instrument off after
a period of approximately 10 minutes. The
power-off state returns to normal when the
function switch is re-set to any position.
Data memory Can store 300 measured results.
Indication Flickers while the instrument is measuring.
Optional Accessory Model7133 (OMA DIEC) distribution board or
lighting circuit test lead for LOOP/RCD/Uc
testing. Data can be transferred to PC via
Optical Adapter Model 8212 (with PC software
