First, measure W
RS(L1L2)
(refer to figure 4).
a. Turn the power on without clamping to any wire.
b. Set the rot
ary 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 ja
ck.
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 t
est probe of V (red) terminal to
the second
phase (eg. R or L1).
f. Clam
p 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 W
TS
(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 m
easurement.
b. Connect the test probe to t
he third phase (eg. T or L3).
c.
Camp the third phase where te
st probe is connected to
(eg. T or L3)
d. The power clamp will automat
ically select proper range.
e. Wait
until the reading is stable (about 3~6 seconds),
press the YELLOW button.
