Converter Power Calibration
- The CONVERTER POWER calibration works in a fashion
similar to the SHORE POWER calibration described above. Press and hold the CONVERTER
POWER
(4)
button for 7 seconds, or until the converter power calibration display appears. Move
the reference meter probes from the input to the output terminal blocks. Then use the
CONVERTER POWER
(4)
button to move the cursor to the parameter to be calibrated. The F1
(13)
button will increment the displayed value, the F2
(13)
button will decrement it. Press the
SYSTEM STATUS
(5)
button to exit the calibration function. Select the CONVERTER POWER
(4)
display to verify the calibration correction factors have been stored.
5)
Generator Power Calibration
- Use an external reference voltmeter to measure the
generator voltage at the generator terminals located on TB12-1, 2, 3, 4. To enter the meter
calibration screen, press and hold the GENERATOR POWER
(3)
button down for 7 seconds, or
until the calibration display appears, then release the button. Use the GENERATOR POWER
(3)
button to move the cursor to the voltage phase to be calibrated. Calibrate the selected parameter
by pressing the F1
(13)
button to increment and the F2
(13)
button to decrement the displayed
value. When all displayed values equal the values measured by the reference meter, pressing the
SYSTEM STATUS
(5)
will store the new calibration values and return the display to the System
Status display. Press the GENERATOR POWER
(3)
button to verify proper shore power meter
calibration.
NOTE: Calibration of the Generator Metering Display is required only when the Seamless Transfer
option is installed
