6.4 Phase rotation test
L LED
and R LED for Phase rotation test may
operate on various wiring systems, but effective
testing result can be obtained only on Three-phase
4-wire system.
►Grasp the instrument firmly and connect both
probes to the object under test.
►Phase-to-phase voltage is indicated by each
Voltage LED.
►R LED lights up for Right rotary field.
Grasp Firmly!!!
►L LED lights up for Left rotary field.
Grasp Firmly!!!
The principle of measurement
The instrument detects the phase rising order
regarding the user as EARTH.
NOTE
Function of this test may not be fully achieved if
the insulation condition of user or of the equipment
under test is not enough.
6.5 Continuity test
WARNING
Make sure the object under test isn’t live.
Instrument operates as follows when measuring
Continuity.
►All LEDs other than Power LED should be
flashing, and buzzer should sound continuously.
NOTE
In continuity mode the instrument works in the
same way as the self-diagnostic test.
6.6 Pen light function
(Illuminating the Measurement Point)
Equipped Pen light illuminates the measurement
point in dimly lit area.
►Pressing the Pen light switch turns on the light.
NOTE
●The light is available while the instrument is
powered off.
●Using the Pen light shortens the battery life.
7. Battery Replacement
WARNING
Remove the probes from any testing point,
when opening the Battery case.
Batteries are dead when Power LED flashes or
goes off at Self-diagnostic test defined in point
4.1. Follow the procedure below and replace
batteries with new ones(type IEC LR03 1.5V).
►Unlock the Battery case with a coin-shaped
object.
Lock Unlock
►Pull out the Battery case and replace the
batteries. Insert new batteries according to the
engraving on the Battery case.
►Insert the Battery case into the instrument and
firmly lock the case again.
WARNING
Confirm that the Battery case is propely
locked prior to measurements.
