Apply a high pressure value to the HART device (100 inW20C shown above) and allow it to stabilize. The
actual value chosen for this pressure point is at the operator’s discretion. When the S1 sensor (or whichever
sensor is selected) reads a steady high pressure value, press the Trim soft key. The sensor will
automatically be trimmed to match the MFT measured value, and the screen will display the prompt:
Remove Pressure. This notice reminds the user to release the pressure applied. Press OK to continue.
The screen will now prompt: Put Loop back online. This notice reminds the user to reconnect the device
under test to the receiving device. Press the OK soft key to continue.
Press the Back soft key to return to the Hart Smart Trim Screen main menu screen. Pressing Back again
will return the MFT to the Calibration key main menu screen.
