HOW TO READ THE AC AMMETER
AND AC VOLTMETER GAUGES
Before taking a reading from either gauge, set the Voltage
Selector Switch (Figure 14) to the position which produces
the required voltage. For example, for 3Ø 240V, choose the
center 3Ø 240/139V position on the voltage selector switch.

GAUGE READING

AC Ammeter Gauge Reading
The AC ammeter gauge is controlled by the AC ammeter
change-over switch.
This switch is located on the control panel and DOES NOT
affect the generator output. It is provided to help observe
how much current is being produced at the UVWO terminal
lugs.
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.
