Analog Output
(mA gauge) Indicates the current value for the analog output of the instrument being commanded by the firmware, in
milliamperes.
% Range
(span gauge) Indicates the current process variable in percent of span determined by the lower range value and the
upper range value.

Tests
LCD Test
— only visible if LCD Configuration is installed
The meter activates all segments immediately after power‐up, during a digital level controller self‐test, or during a
master reset sent by a host supporting HART communications. You can also test the meter by selecting
Turn Cells On
to turn on all display segments, including the analog output bar graph, or select
Turn Cells Off
to turn off all display
segments. When finished with the test, press OK to return the meter to normal display mode.
Loop Test
— used to verify the controller output, the integrity of the loop, and the operations of any recorders or similar
devices installed in the loop. To initiate a loop test, perform the following procedure:
1. Connect a reference meter to the controller. To do so, either connect the meter to the test connections inside the
2. Access
Loop Test
.
3. Select
OK
after you set the control loop to manual.
The Field Communicator displays the loop test menu.
4. Select a discreet milliamp level for the controller to output. At the “Choose analog output” prompt, select
4 mA
,
20 mA,
or
Other
to manually input a value between 4 and 20 milliamps.
5. Check the reference meter to verify that it reads the value you commanded the controller to output. If the readings
do not match, either the controller requires an output trim, or the meter is malfunctioning.
After completing the test procedure, the display returns to the loop test screen and allows you to choose another
output value or end the test.
Primary Calibration
