6.2.3 Current
・
It displays the current value of the load.
・
Press <SHIFT/

> to change R-current, S-current, T-current.
*Before start measuring, select phase and wire system according to the measured load.
When it sets wrong, it doesn’t measure correctly. (Refer to the explanation of setting mode.)
Sample R-current (A)
S-current (A)

・
When input current is under the setting cut-off current, it displays ‘0.0’ and doesn’t measure.

6.2.4 Voltage
・
It displays the voltage value of the load.
・
Press <SHIFT/
▽
> to change voltage, R(RS)-voltage, S(RT)-voltage and T(TS)-voltage.
*Before start measuring, select phase and wire system according to the measured load.
When it sets wrong, it doesn’t measure correctly. (Refer to the explanation of setting mode.)

RT-voltage (V)
TS-voltage (V)
・
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 ‘rated voltage 200(400) x 0.05 x VT ratio’.)
・
When input voltage exceeds 150%F.S. at each range, [
