Multiquip DCA125USJ DCA-125USJ Gauge Reading, How to Read the OutputTerminal Gauges

How to Read the OutputTerminal 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 Output terminals lugs.

Before taking a reading off either gauge, set the Voltage Selector Switch (Figure 17) to the position which produces the required voltage (For example, for 3Ø 240V,

choose the center 3Ø 240/ 139V position on the volt- age selector switch.)

Reading Amperage

To determine the amperage at a terminal lug, set the AC Ammeter Change-Over Switch to the appropriate setting (Figure 20) to activate the AC Ammeter Gauge (Figure 21) 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.

Reading Voltage

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.

To determine the voltage between two terminal lugs, set the AC Voltmeter Change-Over Switch to the appropriate setting (Figure 18) to activate the AC Voltmeter Gauge (Figure 19) 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.
