d. In case of Three Phase/Three Wires (Neutral Grounding System)
(Measuring Mode Y/Ior)
Clamping CT to the grounding line is also available.
(5) Change of Current Range
The current range of this instrument becomes auto after power switch on.
In case that the range cannot be fixed due to the large current fluctuation to be
measured, however, the measurement cannot be done. In this case, fix the current
range by manual mode and make measurement.
(Operation of Manual Range)
1) Press Power Switch
③
once. All display lightens and the mode becomes Io
current measurement (auto range).
2) Press Data Hold Switch
⑧
once (DH sing lightens).
3) Press Current Range Switch
⑤
once ( 10mA, 0.1 lightens).
4) Keeping this condition, press Data Hold Switch once and the range becomes 10mA.
