Active Energy Display

lay format
The following table shows the display format of active energy based on the total load.
※
1. For the direct voltage setting, the direct voltage is used for calculation instead of
the VT primary voltage.
※
2. For 3-phase 4-wire or 1-phase 3-wire, the VT primary voltage and direct voltage
are calculated using the line to phase voltage.

How to change the unit of Wh
When and are pressed simultaneously for 2 seconds, the unit of Wh will be changed. This will enable to check
the upper digits or lower digits of counts.
Note: When the setting value of the VT primary voltage and the CT primary current are large, the lower digits less than a measurement range
display "0".

Wh zero reset
When , , and are pressed simultaneously for 2 seconds, the measured values of Wh and will be
reset.
When the password protection setting is enabled, Wh are reset after you enter the password.
Also, you can clear all Wh values by communication function. (In this case, the password is not necessary.)
(Note 1: This is effective only in the instantaneous value display.)

Each measurement item display during power transmission
The following table shows the symbol display (±) for each measurement value according to the power reception /power sending status.
