First, measure W
RS(L1L2)
(refer to figure 4).
a. Turn the power on without clamping to any wire.
b. Set the rotary switch at 3
φ
3W, and W
L12
symbol will
appear to instruct users to take measurement of W
RS(L2L1)
.
c. Insert the test leads into the input jack.
d. Select one phase (eg. S or L2) as COM and connect the
test probe of the COM (black) terminal to that phase (eg.
S or L2).
e. Connect the test probe of V (red) terminal to the second
phase (eg. R or L1).
f. Clamp the same phase as step e. (eg. R or L1).
g. The power clamp will automatically select proper range.
h. Wait until the reading is stable (about 3~6 seconds),
press the YELLOW button and W
L23
symbol will appear
to instruct users to take measurement of WTS (W
L3L2
).
Second, measure W
TS(L3L2)
(refer to figure 5).
a. Disconnect the test probe from the phase where jaws is
clamp on in previous measurement.
b. Connect the test probe to the third phase (eg. T or L3).
c. Camp the third phase where test probe is connected to
(eg. T or L3)
d. The power clamp will automatically select proper range.
e. Wait until the reading is stable (about 3~6 seconds),
press the YELLOW button.
