TRIM THE TRANSMITTER
Procedure to Trim the Transmitter
For a transmitter with a small differential pressure span, you must
ensure that the transmitter is vertical when mounting it. You do this by
leveling the transmitter side-to-side and front-to-back. See Figure 5 for
suggestions on how to level the transmitter using a spirit balance. You
must also zero the transmitter by following the steps in this table.
Step
Action
1
Attach the transmitter to the mounting bracket but do not
completely tighten the mounting bolts
2
Connect a tube between the input connections in the high
pressure (HP) and low pressure (LP) heads to eliminate the
effects of any surrounding air currents.
3
Connect 24 Vdc power to the transmitter. For HART/DE,
connect a digital voltmeter to monitor the PV output.
4
Use applicable communicator to establish communications with
the transmitter. For DE transmitter use the SmartLine
Configuration Toolkit (SCT3000).
For HART, use MCT404-FDC application or other HART
Communicator with applicable Honeywell DD's.
5
While reading the transmitter’s output on a communication
tool or a voltmeter, position the transmitter so the output
reading is at or near zero, and then completely tighten the
mounting bolts.
6
The local display or applicable communicator can be used to
perform the zero corrects. This corrects the transmitter for
any minor error that may occur after the mounting bolts are
tightened.
7
Remove the tube from between the input connections, the
power, and the digital voltmeter or communication tool.
