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.
