3.0 PRE-INSTALLATION TEST
Prior to installation, the transmitter can be tested and operated from the HART Communicator. This test
consists of checking that the transmitter is operational and that all configuration information is correct.
Section 5 Post-Installation Test provides an on-line test procedure. For an in-depth discussion of
transmitter configuration, refer to Section 6 On-Line Configuration and Operation.
IMPORTANT
Transmitter orientation will affect the analog output zero. Refer to Section 7.1
Calibration for details.
3.1 PROCEDURE
A complete transmitter functional test can be performed and configuration procedures can be practiced.
To operate the transmitter on a test bench, make the connections shown in Figure 3-1. Figure 3-2 shows
the connections if these tests are to be performed after transmitter installation. A pressure source can also
be connected.
