Setting Menu
HOME page (HOME): Values measured by the power meter, including average voltage (Vavg (AVG)),
average current (Iavg (AVG)), total real power (Ptot (SUM)).
Phase voltage (VLN): Phase voltage values measured by the power meter, including phase A voltage
(VL1N(V)), phase B voltage (VL2N(V)), phase C voltage (VL3N(V)).
Line voltage (VLL): Line voltage values measured by the power meter, including A-B line voltage
(VL12(V)), B-C line voltage (VL23(V)), C-A line voltage (VL31(V)).
Electric current page (Current): Electric current measured by the power meter, including phase A current
(IL1N(A)), phase B current (IL2N(A)), phase C current (IL3N(A)).
Power factor page (PF/F): Power factors measured by the power meter, including total power factor (PF)
and frequency (F(Hz)).

Power page (Power): Values measured by the power meter, including total active power (Ptot(W)), total
reactive power (Qtot(var)), and total apparent power (Stot(VA)).
Active power page (Active Power): Active power value measured by the power meter, including active
power of phase A (L1N(W)), phase B (L2N(W)) and phase C (L3N(W)).
Reactive power page (VAR): Reactive power value measured by the power meter, including reactive
power of phase A (A), phase B (B), phase C (C) and total reactive power (T).
Apparent power page (Apparent Power): Apparent power value measured by the power meter, including
apparent power of phase A (L1N(VA)), phase B (L2N(VA)) and phase C (L3N(VA)).
Energy page (Energy): Energy values measured by the power meter, including positive active energy
(Wh+), positive reactive energy (var+), positive apparent energy (VA+), reversed active energy (Wh-),
reserved reactive energy (var-) and reserved apparent energy (VA-).
(Reversed active/ reactive/ apparent energy are supported by firmware version 1.02 and after.)

Use UP and DOWN to switch among setting pages.
2.
Press BACK to return to the homepage (Home) on other setting pages.
3.
Note(1): When on the homepage, press BACK to enter the correct password and enter setting
pages.
4.
Note(2): Values of positive reactive energy would be displayed with inductance icon, while values
of reversed reactive energy would be displayed with capacitance. For values of reversed active energy
and apparent energy, a minus sign would be displayed.
5.
Note(3): The real-time status of active/ reactive power would be displayed on all measurement
display pages with four P-Q quadrants. Inductive and capacitive state would be shown on the PF value
display for positive/ reversed reactive energy. Four P-Q quadrants and inductive/ capacitive state would
not be displayed when average current is under 20mA.
The following figure is shown with a reversed reactive energy value, which the real-time status of active/
reactive power is displayed with a four P-Q quadrant icon.
