Torch Light; Battery Replacement - Megger TPT420 Bedienungsanleitung

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 the probes to the object
under test, each probe to one of the phases
that should be tested. 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
