6.1.4 Voltage
・It displays the voltage value of the load.
・Press to change voltage between P1 and P0, P2 and P0, P3 and P0.
*Before start measuring, select phase and wire system according to the measured load.
When 1P3W or 3P3W is selected, it doesn't measure 1P2W system correctly. When 3P4W system is
selected, it doesn't measure 1P2W, 1P3W, 3P3W system correctly.
Select phase and wire system according to the measured system. (Refer to the explanation of setting
mode.)

Lighting
・When input voltage is under 5% of rating, it displays "0.0" and doesn't measure.
("Under 5%" means the value getting from this calculation
・When input voltage exceeds 150%F.S. at each range, 「- - - -」 will be displayed.
