Operation and Maintenance

Recall factory trim

The Recall Factory Trim button will restore the transmitter to the original factory characteriza-

tion curve. The Recall Factory Trim button can be useful for recovering from an inadvertent zero

trim or inaccurate pressure source.

When the recall factory trim function is used, the transmitter’s upper and lower trim values are

set to the values configured at the factory. If custom trim values were specified when the

transmitter was ordered, the device will recall those values. If custom trim values were not

specified, the device will recall the upper and lower sensor limits.

Last static pressure sensor trim

The current upper and lower trim points can be seen under the Last Static Pressure Sensor Trim

Points heading.

Calibration type

The calibration type drop-down menu allows the user to note the type of device last used to

calibrate the sensor (either Differential, Gage, or Absolute). This field does not affect the

calibration of the device.

4.3.5 Process temperature sensor calibration

The Temperature Calibration tab allows the user to perform a sensor trim and configure the

sensor matching of a process temperature sensor, see Figure 4-4.
