Application: this function will compensate for changes in output voltage not already corrected by
hardware and software calibration such as load-dependent output voltage variances. This
function should be disabled before calibrating the hardware oscillator and current compensation
pots on the Modulator Interface PCB (usually only done when initially setting the output voltage
configuration at the factory). It must be disabled when using Converter Output Impedance
Control (see page 48).

kW-HOUR METER AND MAXIMUM POWER LEVEL DISPLAY
Press the SHORE POWER + CONVERTER POWER buttons to access the Automatic KW-
HOUR METER and maximum power level display.
Press the Clear
(F1)
button to clear all data and the Exit
(F5)
button to exit.
Application: this reference kW-hour meter can be used to check the billing received in a marina.
Immediately after connecting shore power and turning the converter's red disconnect switch,
clear the data in this screen. When ready to leave, take down the kW-hours and run time before
disconnecting the shore power. Additionally, this screen can be used to diagnose converter
shutdowns. Since the Max. Level and Max. Power data are updated with slow-response
metering (approximately 1 second), only average use data are represented. Instantaneous motor-
start surges and such will not be represented by the data. If the Max. Level exceeds 110%, and a
shutdown of the Shore Power has occurred, it is very likely the average loading is exceeding the
converter's capacity. The Max. Power is provided since Max. Level is affected by Shore Cord
Setup settings.
