9 CALIBRATION
In an uncalibrated state the input and output voltage and input current metering system should be
within 3%. The uncalibrated output current meter is normally 5% low. For calibration an external
reference voltmeter will be required along with a calibrated current transformer or probe. If the
system is to be calibrated on board using the yacht’s loads, attempt to shut down all transient
(fluctuating) loads if possible. Cyclic loads will complicate the current meter calibration process.
This procedure must also be followed after replacing the battery on a maintenance basis
1)
Turn the system off and secure input power. Remove the front cover.
2)
Remove the lower front protective panel from the system, and set it aside. The input and
output power terminal blocks will be located at the bottom of the power panel located in the
lower compartment. Refer to the installation section of the Operations Manual for additional
information. Re-apply power to the system and bring the system on-line. Transfer the
yacht’s load
(or external test load bank)
to the converter.
3)
Shore Power Calibration
- Press the SHORE POWER
(2)
button under the LCD
(1)
display. Use an external reference meter and current transformer or clamp to measure the
input
(shore power
) power at the input terminal block. Shore Power voltages are measured
phase-to-phase. To enter the meter calibration screen, press and hold the SHORE POWER
(2)
button down for 7 seconds, or until the calibration display appears, then release the
button. Use the SHORE POWER
(2)
button to move the cursor to the parameter to be
calibrated, voltage or current. Change 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 SHORE POWER
(2)
button to verify proper shore power meter calibration.
