7.11 CALIBRATION
In an uncalibrated state the input and output voltage and input current metering system should be within
5%. For calibration, an external reference voltmeter will be required along with a calibrated current
transformer or probe. If the converter is to be calibrated 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 converter and bring it 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 button to increment and the F2 button to
decrement the displayed value. Press the SYSTEM STATUS (5) button to store the new values
and exit the calibration function. Press the SHORE POWER (2) button to verify proper shore
power meter calibration.
