CALIBRATION AND MAINTENANCE

NOTE

Removing a transmitter can interrupt power to other transmitters powered from a common power source. Note the effect this can have on process control and operation and, if necessary, follow the proper procedures to shut down the process.

When disconnecting the SIGNAL leads, carefully insulate each lead as it is removed to prevent accidental electrical shorts.

2.Remove the enclosure cap for access to the terminal compartment

3.Connect MXC and DMM (milliammeter) to the loop as shown in either Figure 6-1 or 6-2. Set DMM to measure 4-20 mA.

Field Calibration Wiring - Open jumper at Circuit Junction.

4.Place loop in Manual mode.

5.Apply power to the Loop.

6.Establish communication between MXC and transmitter. Refer to Section 3.2 as necessary.

If the transmitter is configured for digital mode, reconfigure for analog mode by setting the short address to zero (0). Refer to Section 5.1.1.3 as necessary.

7.At the Main Menu, select the CAL/TEST program.

Step through the MXC screens and use the PREV and NEXT buttons to select the DAC OUTPUT calibration. Press SELECT (F4).
