Total Power kVA and kW displays alternator output as actual output values.
Rated Power displays alternator output as a percentage of the entered data value.
Volts displays the alternator output AC voltages. The display shows all line-to-line and line-to-neutral voltage combinations for
three-phase or single-phase configurations.
Current displays the alternator output AC amps. The display shows each line (L1-L2-L3) of three-phase models or L1-L2 current
for single-phase models.
Frequency (Hz) value displays for the output AC voltage. This value also shows in the Overview Menu.
Reset Calibration providing the means to reset the configuration values is available in this menu.
The calibration values are reviewable at all times and provide the calibration of the voltage and current sensing logic. Changing
the system voltage or replacing the circuit board requires a calibration adjustment.
To enable calibration, start the generator set and select the Volts L1-L2 display. Then push and hold the pushbutton/rotary
selector dial until the Calibration Enabled popup appears. Calibration of each display is now available. The display will show the
following values for three-phase generator sets. Single-phase generator sets will only display items marked (*).

Volts L1-L2 *

Volts L2-L3

Volts L3-L1

Volts L1-N *

Volts L2-N *

Volts L3-N

Current L1 *

Current L2 *

Current L3
The user can change individual values or can select Reset Calib?-Yes to reset all values. The Reset Calib? display will only
show if calibration is enabled. Refer to the requirements shown with Generator Set Calibration in the section titled: Status and
Notice Digital Displays.
To disable calibration, rotate the pushbutton/rotary selector dial until the <-Return popup appears. Momentarily press the
pushbutton/rotary selector dial. Stop the generator set if not already done.
