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 → CONFIG → PLANT.
Using the Arrow keys, reset the plant voltage reading by
selecting RST PLV. Press to reset. This will
remove any pre-existing user calibrated values if they exist.
3 Press the
→ DC PLT screen. Move to ADJ PLV on the menu
and use the keys to calibrate the plant voltage to
match the reading of the DVM. Press to use the
new calibrated plant voltage.
4 Press the 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.
