3Φ
1.First, measure WR(L1) (refer to the diagram below).
a.Set the rotary switch to the “ 
V ” position.
b.Press and hold the “RANGE” key while setting the rotary switch to the “KW/KVA” position, the 3φ4W and WL1 symbols should appear.
c.Insert the test leads into the input jacks.
d.Connect the neutral line to the COM (black) terminal.
e.Connect the test probe of the V (red) terminal to the first phase (e.g. R or L1).
f.Clamp on to the same phase (e.g. R or L1).
g.The power clamp meter will automatically select the proper range.
h.Wait until the reading is stable (about 6 seconds) and then press the “HOLD” key;
the WL1 symbol will clear and the WL2 symbol will appear in order to instruct users to take the WS(L2) measurement.
2.Second, measure WS(L2) (refer to the diagram that follows the steps below)
a.Disconnect the test probe from the phase where the jaw was clamped in the previous measurement.
b.Connect the test probe of the V (red) terminal to the second phase (e.g. S or L2).
c.Clamp on to the phase where the test probe is connected (e.g. S or L2 phase)
d.The power clamp will automatically select proper range.
e.Wait until the reading is stable (about 6 seconds) and then press the “HOLD” key;
the WL2 symbol will disappear. The WL3 symbol will appear to instruct users to take the WT(L3) measurement.
