The AC ammeter and AC voltmeter gauges are controlled
by the AC ammeter and AC voltmeter change-over
switches.
Both of these switches are located on the control panel and
Do not effect the generator output. They are provided to
help observe how much power is being supplied, produced
at the UVWO terminals lugs.
Before taking a reading from either gauge, configure the
Voltage Change-Over Board (Figure 13) which produces
the desired output voltage.

aC voltmeter gauge reading
Place the AC Voltmeter Change-Over Switch (Figure 14)
in the W-U position and observe the phase to phase voltage
reading between the W and U terminals as indicated on
the AC Voltmeter Gauge (Figure 15).

aC ammeter gauge reading
Place the AC Ammeter Change-Over Switch (Figure 16)
in the U position and observe the current reading (load
drain) on the U terminal as indicated on the AC Ammeter
Gauge (Figure 17). This process can be repeated for
terminals V and W.

NOTICE
The ammeter gauge will only show a reading when
the Output Terminal Lugs are connected to a load
and in use.
