4.8 Changing the Measurement Method (Auto/Manual)
68
The selected network, class and measurement mode determine what measurement items will appear.
See Appendix2 "List of instrument status, other test condition and special test condition"(p.A4)
Setting automatic measurement items
1.
On the automatic measurement setting screen, press to display the automatic measure-
ment item setting screen.
2.
Turn automatic measurement for each measurement item ON or OFF.
Each time a key is pressed, the indication switches between ON and OFF.
Equipment with an internal power supply cannot be set.
See "Line phase in leakage current measurement
between enclosure and line" (p. 69)
1. Power supply polarity
Indicates "positive phase."
Indicates "negative phase."
2.Condition of equipment under test
(power supply)
Sets "Normal condition."
Sets a "Single fault condition"
(power supply lead is disconnected).
Sets a "Single fault condition"(protective
earth terminal is disconnected).
