Display format
The following table shows the display format of active energy / reactive energy / apparent energy based on the total
load.
Total load power[kW] =
※ 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, varh and VAh

When and are pressed simultaneously for 2 seconds, the unit of Wh, varh and VAh will be changed. This will
enable to check the upper digits or lower digits of counts.
Example of change: Case of active energy (imported) = 012,345,678,901,234.567Wh
Press and
Unit：Mega
Note1: All of Wh, varh and VAh change to same unit even if these are not shown on the screen.
Note2: 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, varh and VAh zero reset

When , ,and
RESET
VAh will be reset.
When the password protection setting is
Also, you can clear all Wh, varh and VAh values by communication function. (In this case, the password is not
necessary.)
Note 1: This is effective only in the instantaneous value display.
Note 2: All of Wh, varh and VAh will be reset even if these are not shown on the screen.
Note 3: The periodic active energy will not be reset. Another operation is necessary. (Refer to page 72)
