Meter Calibration from the Front Panel
Voltage Calibration
Step Action
1 Using a calibrated DVM, measure the plant voltage from the
front panel voltage test jacks.
2 From the front panel press <MENU> → CONFIG → PLANT.
Using the Arrow keys, reset the plant voltage reading by
selecting RST PLV. Press <ENTER> to reset. This will
remove any pre-existing user calibrated values if they exist.
3 Press the <MENU> key, wait five seconds, and go back to the
CONFIG
→ DC PLT screen. Move to ADJ PLV on the menu
and use the <ADJUST> keys to calibrate the plant voltage to
match the reading of the DVM. Press <ENTER> to use the
new calibrated plant voltage.
4 Press the <ESCAPE> key until the default screen is displayed.
Verify that the plant voltage reading reflects the same reading
as shown on the DVM. Note that in a serial plant, the actual
plant voltage reflected by the DVM will change, not the
reading reflected on the display.
