AC ammeter
This meter indicates AC current flowing into the
connected load. Make sure that it is always
pointing below the rated current.
When miming the three phase and single phase
loads together, this meter indicates total current of
them.
Ammeter change-over switch
When running either the three phase or single
phase load, this meter indicates the current flowing
into the load.
The current of each phase can be checked using
the ammeter change-over switch.
(3) AC voltmeter
This meter indicates AC output voltage. Make
sure that it indicates rated voltage.
Line-to-line voltages can be checked using the
voltmeter change-over switch.
