9. Additional fields on these screens, which are listed below, are for display purposes
only and are not configurable by the user.

Mode – On the Current Output A tab, this field always displays Normal at
this time. On the Current Output C tab, this field displays whether the gauge
is connected to a Hart Communication Protocol.

Live Value (EU) – This field displays the live calibrated value in engineering
units in both Live and Manual modes.

Calibration Points – This field displays the number of points the current
information used to calibrate the current input.

#1 mA Min Value – This field displays the expected minimum analog input
value provided by the user during calibration.

#2 mA Mid Value – This field displays the expected midpoint analog input
value in a three point calibration provided by the user during calibration.

#3 mA Max Value – This field displays the expected maximum analog input
value provided by the user during calibration.

#1 Raw Min Value – This field displays the measured minimum value read
from the device.

#2 Raw Mid Value – This field displays the measured midpoint value read
from the device.

#3 Raw Max Value – This field displays the measured maximum value read
from the device.

Status – This field displays one of the following:

Live – Current output is being driven by the selected measurement ID.

Hold – Current output is being driven based on the Hold Value (EU).

Low Alarm – The current output value is below the Min Current value.

High Alarm – The current output value is above the Max Current value.

Fault Low Alarm – The current output is below the value defined by the
Namur standard.

Fault High Alarm – The current output is above the value defined by the
Namur standard.
Calibration
Current outputs can be calibrated using two or three points. The calibration process
for the current outputs should be completed by selecting Calibration from the
Functions menu or by clicking the fourth icon button, the wrench. Selecting either of
these options will guide the user through the calibration process step-by-step. For
further information, see
