ROTATION TEST
•
Three-phase voltage test range: 57V~400V (50Hz~60Hz).
•
Connect the L2 test pen to any phase and the L1 test pen to any of the remaining
phases. The L or R LED will illuminate.
•
Once the second test pen is connected to a second phase, L or R will illuminate
based on the phase relationship.
•
The L or R LED will illuminate
conversely when the position of
the two test pens are exchanged.
•
An LED will indicate the
corresponding voltage or
the LCD will display the
corresponding voltage value.
•
The indicated or displayed voltage should be the phase voltage against earth.
Notes:
•
For measuring the three-phase AC system, as the tester only has two test pens,
it is required to form the reference terminal by holding the tester handle with your
fingers, therefore it would not accurately indicate the phase sequence of the three-
phase system if you were wearing insulating gloves.
•
It is necessary to ensure the earth terminal of the three-phase system is in contact
with the human body while measuring a three-phase power system lower than
100V.
RCD TEST
•
For an RCD trip test, connect the two test pens to the L and PE terminals of the
230V AC system under normal voltage measurement mode and press the yellow
RCD key on the two test pens.
•
The RCD system should trip and the LED indicating RCD (72-3570/72-3575) or
the RCD symbol (72-3580) will illuminate if the circuit then generates AC current
higher than 30mA.
•
At 230V, testing time should be <10s.
•
The meter cannot conduct continuous measurement. After one test wait 60
seconds before the next measurement.
Notes:
•
In the case of no measurements or tests, it is normal to have continuously
illuminated LEDs and a continuously sounding buzzer after simultaneously
pressing RCD keys on two test pens.
•
To avoid a malfunction, do not press the two RCD buttons under non-RCD testing
mode.
