8. Phase sequence testing
(Three-phase AC phase sequence indication)
This test must follow the security testing rules mentioned in
Point 3 of the manual.
● When testing phase sequence under strong electric field
interference or strong radiation, the test results may be
unstable.
● The rotation test is indicated by symbol and symbole R, and
it is only applicable to three-phase AC systems.
1. Range of three-phase voltage test: 57V~400V (50Hz~60Hz).
2. When testing, hold the main end of the tester with the hand
(fingers on the handle part), as shown in the figure below, and
connect the probe L2 to any one of the three phases of the
electric circuit, and connect the probe L1 to any other phase.
3. One of R or L will be displayed, and if one of the probes is
moved to another phase, the other (L or R) will be displayed.
4. If the positions of two probes are exchanged, L or R will also
be displayed.
5. At the same time, the LCD displays the corresponding
voltage value, indicating or displaying the relative voltage , not
the three-phase voltage.
