Three LEDs indicate if the wiring of the circuit
under test is correct.
Detects overheating of the internal resistor
(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.
Loop impedance 2000Ω range 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).
Allows testing of RCDs which are sensitive to
DC fault currents.
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.
Select UL 25V or 50V with pressing the UL
value select switch. Where Uc value exceeds
UL, "UcH v" will be displayed without starting
the RCD test.
And at Uc range, can monitor the Uc value.
Holds the displayed reading until pressed
or rotated any switches after the test is
complete and at Loop/RCD/Uc range, until the
succeeding supply is applied.
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.
Can store 300 measured results.
Flickers while the instrument is measuring.
Model 7133B (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
"KEW Report")
