Figure 7 TechCheck Calibrator (Calibrate Actuator Pressure Sensor window)

To perform an actuator pressure sensor calibration:

1. Type in the supply pressure if the displayed pressure differs from the actual

pressure.

2. Click on the Start button. The attached device automatically performs the

calibration using the embedded internal calibration data.

NOTE: You must complete the entire procedure. The positioner is "offline" during

calibration and does not return to service until the procedure is complete.

Click on Calibrate Current Loop to display the Calibrate Current Loop window. Perform

this procedure to correctly calibrate the 4-20 mA input signal. This is a linear two-point range

calibration on the input signal sensed by the Logix positioner. It requires that you set both

the minimum and maximum current levels the positioner will sense as a command signal.
