5.0 POST-INSTALLATION TEST
This section provides guidelines for performing a post-installation test or commissioning. These steps
include:
•
Performing an installation review to verify that the proper transmitter is installed and that it is
installed correctly. See Section 5.2.
•
Testing HART communications and performing a transmitter self test. Exercising the transmitter over
its configured range and checking analog output accuracy. See Sections 5.3 and 5.4.
•
Adjusting shutoff valves to set transmitter zero and prepare for on-line operation with live process
pressures. See Section 5.5.
If a pre-installation test of the transmitter was not performed, review Section 3 Pre-Installation Test as the
described tests can be performed after installation.
5.1 TEST EQUIPMENT
•
User configuration data for the transmitter(s)
•
HART Communicator (see Section 2 of this manual)
•
Laboratory grade digital multimeter (DMM); for calibrating the 4 to 20 mA output signal; a meter
certified for use in intrinsically safe circuits must be used in an intrinsically safe installation

5.2 INSTALLATION REVIEW
1. To ensure the correct transmitter model has been installed, note the model designation and
certifications on the transmitter's rating and approval plates. Compare this information to the model
specified in user's documentation (P&I drawing).

WARNING
Explosion can cause death or serious injury.
Only a certified ammeter may be used in intrinsically
safe circuits.
In a Division 1 area, where an explosion-proof rating is
required, remove power from the transmitter before
removing either enclosure cap.
