attempting to operate or service the meter.
To avoid damages to the instrument do not exceed the maximum
limits of the input values shown in the technical specification
tables.
Do not use the meter or test leads if they look damaged. Use
extreme caution when working around bare conductors or bus
bars.

Connect the test probe of COM (black) terminal to the
neutral line.
Connect the test probe of V (red) terminal to the power line.
Clamp the conductor where V (red) terminal is connected.
The power clamp will automatically select the appropriate range.
Read the Watt and PF values displayed on the LCD.
Press YELLOW button to select KW/PF, A/V, or KVA/PF.
KVAR is a calculated value, and its accuracy greatly
depends on the accuracy of V, A and KW especially when
PF is very close to 1. To get a more accurate value when
PF is greater than 0.91 (φ< 25°), users can obtain KVAR by
themselves from the following equation for pure sine wave
input :
PF KW
KVA
=
KVA (Apparent Power) : KVA = VA*

First, measure WRS(L1L2) (refer to figure 4).
a. Turn the power on without clamping to any wire.
b. Set the rotary switch at 3φ3W, and WL12 symbol will
appear to instruct users to take measurement of WRS(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 WL23 symbol will appear
to instruct users to take measurement of WTS (WL3L2).
Second, measure WTS(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.

The power clamp will process those two sets of data (WL12,
WL23), and show the result on the LCD. WL123 symbol will
be shown to indicate the watt of 3φ3W power.
At this moment, the watt of 3φ3W power is stored into the
memory.
If willing to read the details of that singly data record,
please refer to 5-9.

If willing to record data (WL12 or WL23), press “RECORD”
button to complete.
NOTE
Once a phase is selected as COM, users can not change this
selection in the subsequent measurement. For example, if S (or
L2) phase is selected, S (or L2) phase is always connected to the
COM during measurement of WRS (or WL1L2) and WTS (or WL3L2)
in 3φ3W unbalanced power.
NOTE
The "+" sign printed on jaw must face the power source, and
make sure all the connections and clamping are correct for correct
measurement.
NOTE
In the 3φ3W unbalanced power measurement, one of WRS or
WTS could be negative. Users must make sure all the
connections and clamping are correct to obtain correct power.
