L1L2 Measurement
• Select one phase to be the common phase. (eg. S or L2)
• Connect the black test probe to the common phase (S or L2)
and the red test probe to another phase (eg. R or L1).
• Using the trigger to open the jaws, fully enclose the phase
(R or L1) within the clamp.
• Release the trigger and be sure that the jaws have closed
completely.
• Wait until the reading is stable, and press the READ NEXT
button to capture the reading, storing the data in memory.
• The LCD display will show a flashing T to indicate that the
meter is ready for the next measurement.
• Remove the clamp and test probes from the phases tested in
the first measurement.
Note: Once a phase is selected as common, this selection
cannot be changed. For example, if S or L2 phase is select-
ed, S is always connected to COM during measurement of
in 3 φ 3W unbalanced power.

L3L2 Measurement
• Connect the black test probe to the common phase (S or L2)
and the red test probe to the third phase (eg. T or L3)
• Using the trigger to open the jaws, fully enclose the phase (T
or L3) within the clamp.
• Release the trigger and be sure that the jaws have closed
completely.
• Wait until the reading is stable, and press the READ NEXT
button to capture the reading, storing the data in memory.
