Phase rotation test
L LED and R LED’s for the Phase rotation test
may operate on various wiring systems, but an
effective test result can only be obtained on
three-phase 4-wire systems.
Hold the tester and remote probe firmly in each
hand, ensuring hands are behind the hand
barriers, and connect both probes to the object
under test. Phase-to-phase voltage is indicated by
voltage LEDs and LCD display.
R LED lights up for Right rotary field. (L1, L2, L3)
L LED lights up for Left rotary field. (L1, L3, L2)
Measurement principle: The instrument detects
the phase rising order referencing the user as
earth. The function of this test may not be fully
achieved if the insulation condition/ grounding
conditions of user or of the equipment under
test are not good enough.
Torch light
Pressing the torch light button will turn on
the light and after approximately 10s it will
turn itself off.
Battery Replacement
Remove the probes from any testing point, when
opening the battery cap. Batteries are exhausted
when the continuity test with both test probes
connected cannot be achieved anymore. A
battery symbol
+ 1.5 V AAA -
in the LCD display
indicates low battery.
Follow the procedure below and replace batteries
with new ones (type AAA / IEC LR03 1.5 V).
Unscrew the battery cap, e.g. with a screwdriver.
Pull out the battery cap and replace the batteries.
Insert new batteries according to the engraving
on the battery cap and re-assemble battery cap.
Confirm that the battery cap is properly locked
prior to measurements.
