DCA-45USI — GAUGE READING
How to Read the Output Terminal Gauges.
The gauges and selector switches on the control panel
DO NOT effect the generator output. They are provided to
help observe how much power is being supplied at the
Out-
put Terminal Lugs.
Before taking a reading off either gauge, set the Voltage
Selector Switch (Figure 16) to the position which produces
the required voltage (For example, for 3Ø 240V, choose the
center 3Ø 240/139V posi-
tion on the voltage selector
switch.)

For 3Ø 208V/1Ø,120V, place
the Voltage Selector Switch
in the 3 Phase 340/139
position.

The ammeter gauge will only
show a reading when the
Output Terminal Lugs are
connected to a load and in use. NOTE
Reading Voltage
To determine the voltage between two terminal lugs, set the
AC Voltmeter Change-Over Switch to the appropriate
setting (Figure 17) to activate the
AC Voltmeter Gauge
(Figure 18) and read the available voltage between the two
lugs.
For example, to measure the voltage between the W and U
terminal lugs, set the
AC Voltmeter Change-Over Switch
to W-U and read the AC Voltmeter Gauge.
NOTE
Reading Amperage
To determine the amperage at a terminal lug, set the
AC Ammeter Change-Over Switch to the appropriate
setting (Figure 19) to activate the
AC Ammeter Gauge
(Figure 20) and read the available amperage at the terminal
lug.
For example, to measure the amperage at the U
terminal lug, set the
AC Ammeter Change-Over Switch to
U and read the AC Ammeter Gauge.
