<MENU> key, wait five seconds, and go back to the Config → DC Plt
screen. Move to ADJ PL
V on the menu a
nd 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. Press the
<ESCAPE> key until the default screen is displayed. Verify that the
system voltage reading reflects the new value.
Note that in a serial plant, the actual plant voltage reflected by the DVM
will change, not the reading reflected on the display.
Current
Calibration
The following procedure is applicable only in plants with Load
shunts in a plant configured for centralized architecture.
Using a calibrated DVM, measure the plant load from the front panel
current test jacks in mV.
To calculate the plant load, in amperes, as measured by the DVM, divide
the mV DVM reading by the rated shunt mV value. Multiply this result
by the shunt ampere rating. This value is the plant load measured by the
DVM, in amperes.
From the front panel press Menu → Config → Plant. Using the Arrow
keys, reset the plant current reading by selecting RST PLI. Press the
<Enter> key to reset. This will remove any pre-existing user calibrated
values if they exist. Press the <Menu> key, wait five seconds, and go
back to the Config → Plant screen. Move to ADJ PLI on the menu and
use the <ADJUST> keys to calibrate the plant load to match the
calculated plant load value. Press <ENTER> to use the new calibrated
plant load. Press the <ESCAPE> key until the default screen is
displayed. Verify that the plant load reading reflects the new value.
