3.The power clamp will process these two sets of data (WL12 , WL23), and show the result on the LCD. The WL123 symbol will be shown to indicate 3φ3W power. The 3φ3W power (in watts) is stored in the meter memory.
4.To read a single data record, press the “HOLD” key to select desired WL12 , WL23 or WL123 display then press the “RANGE” key to select KW+HP (Horse Power),
KW+PF (Power Factor), KW+KVAR, KVA+θ(Phase Angle) or A+V.
5.W3φ3W = WRS(L1L2) + WTS(L3L2)
KVA3φ3W = 
KW 23φ3W + KVAR23φ3W
PF3φ 3W = KW 3φ 3W
KVA 3φ 3W
6. Set the rotary switch to another position to exit this mode and clear the stored data.
