To calibrate the sensor with a HART Communicator using the full trim function, perform the following procedure:

1.Assemble and power the entire calibration system including a transmitter, HART Communicator, power supply, pressure input source, and readout device (see Figure 2-9).

NOTE

Use a pressure input source with sufficient accuracy and allow the input pressure to stabilize for 10 seconds before entering any values.

2.From the communicator menu select 1 Device setup, 2 Diagnostics and service, 3 Calibration, 3 Sensor trim, 2 Lower sensor trim to prepare to adjust the lower trim point.

NOTE

Select pressure input values so that the low and high values are equal to or outside the 4 and 20 mA points. Do not attempt to obtain reverse output by reversing the high and low points. The transmitter allows approximately a 5% URL deviation from the characterized curve established at the factory.

3.Follow the commands provided by the communicator to complete the adjustment of the lower value.

4.Repeat the procedure for the upper value, replacing 2 Lower sensor trim with 3 Upper sensor trim in Step 2.
