Instrument has the upper, middle, and lower three display windows. Each value and unit 

symbol form the data. For example, the upper window shows 100.0V, it is to say phase A 

voltage is 100V.   

F1, F2 and on the bottom are to switch three windows and recycling display parameters.   

Symbols meaning:   

V: phase voltage symbol; Unit: V combined with K or M = kV MeV   

V LL two symbols denote a line voltage; Unit: V, and combined with K, M to kV MV;   

A: Current Symbol; Unit: A, and combined with K, M to kA, MA;   

W: active power symbol; Unit: W, and combined with K, M to kW, MW;   

Var: reactive power symbol; unit: Var, and combined with K, M to kVar, MVar;   

VA: Apparent power symbol; Unit: VA, and K, M combination kVA, MVA;   

Hz: Frequency Symbol; Unit: Hertz;   

PF: Power Factor symbol;

 

E: energy symbols; Unit: Ep (active power) kWh, Eq (reactive energy) kVAh, Es 

(apparent power) kVA;   

3P3L: 3-phase 3-wire two components;   

3V3A: 3-phase 3-wire three elements;   

3P4L: three-phase four-wire;

 

(2) Display the voltage & current: 

In the non-setting state press F2. Current and voltage

will be displayed. For example, in the 01 interface (see the following pictures), press the 

F2 key to switch to 02 interface. When in 03 interface press the F2 key to return to 01 

interface. Switch the display process shown below:
