5.10.2. PHASE SEQUENCE MEASUREMENT
Measured quantities and display ranges:
Phase sequence 1.2.3. or 2.1.3.
Phase-to-phase voltage UL1/2 360 460 V
Phase-to-phase voltage UL2/3 360 460 V
Phase-to-phase voltage UL3/1 360 460 V
1) Select the PHASESEQ function by pressing the FUNC hard key first.
2) Connect the test leads to tested socket/wiring according to the figure below.

3) Carry out the measurement by pressing the START button. The measurement will be done and
test result will be displayed in green colour equipped and with beep-beep sound if it is in
accordance with referential direction (1.2.3.). If the result is not in accordance with referential
direction (2.1.3.) then it will be displayed in red colour equipped and with longer beep sound. See
the display outlook with test result on the figure 38.
4) Save the test result by pressing the SAVE hard key twice, for further instructions see the

5) Press the EXIT hard key to clear displayed result, actual input voltages UL1/2, UL2/3, UL3/1 will start
to be displayed again.
The following specific information can be shown on the display during the measurement:
Information displayed Description
VOLTAGE OUT OF RANGE
One or more phase-phase voltages are out of required
range (360 460 V).
1.1.X
At least one of measured phases was disconnected during
the measurement.
Connect all three phases and repeat the measurement.
