5.3.5 Calibration of the Current Output (I
out
)
Menu:
SETUP / [CONTROLLER /] SYSTEM / TEST / CURRENT OUTPUT
Procedure for 4 mA output calibration
1. Select the 4 mA Out Adjust menu option.
2. Measure the output current from the Current Output (I
out
) terminal.
(See "Electrical installation” on page 13 for terminal layouts and connection diagrams).
3. If the measured current is not 4 mA, edit the existing value to be the actual mA reading
and then save it.
Procedure for 20 mA output calibration
1. Select the 20 mA Out Adjust menu option.
2. Measure the output current from the Current Output (I
out
) terminal.
(See "Electrical installation” on page 13 for terminal layouts and connection diagrams).
3. If the measured current is not 20 mA, edit the existing value to be the actual mA
reading and then save it.

D804 Ullage
This indicates how much a vessel or open-channel falls short of being full. It is calculated
as the difference between the upper range value (URV) of the Current Output and the
control unit PV i.e. D804 = (P401 - D800)
