Use the Inc / Dec soft keys to make changes. Use the Next soft key to move to the next character. Press
the Done soft key when the changes are complete. A prompt will appear: Save new data? Press the Yes
soft key to accept the changes. Pressing the No soft key will delete the changes and keep the previous
settings. The MFT will now return to the Rerange main menu.
Set 4mA Range: This option allows the user to configure the pressure value at which the HART device will
read 4 mA. Move the cursor to Set 4mA and press the Select soft key.
The screen will prompt: Take Loop offline. This notice reminds the user that the device output will not be a
measurement of the actual process, and to place the receiving device or control system (such as a chart
recorder, PLC, or DCS) in manual mode. Press the OK soft key to continue. Press the Back soft key to
return to the Rerange main menu screen.
After pressing OK, the screen will prompt: Apply new 4ma input. This screen prompts the user to apply
the pressure that will become the lower range value. Press the OK soft key to continue and the following
screen will appear. Press Back to escape.
With pressure connections teed to the MFT and the HART device, apply the desired pressure and press the
Select soft key. The MFT will then configure the pressure applied to equal 4 mA. To set 4 mA to
correspond to zero pressure, make sure HART device is vented to atmosphere.
The screen will display the prompt: Put Loop back online. This notice reminds the user to return the
device to service. Press the OK soft key to continue. The MFT returns to the Rerange main menu screen.
Press the Back soft key to return to the Sensor main menu screen. Pressing Back again will return the
MFT to the Device Config screen.
Set 20mA Range: This option allows the user to configure the pressure value at which the HART device
will read 20 mA. Move the cursor to Set 20mA and press the Select soft key.
The screen will prompt: Take Loop offline. This notice reminds the user that the device output will not be a
measurement of the actual process, and to place the receiving device or control system (such as a chart
recorder, PLC, or DCS) in manual mode. Press the OK soft key to continue. Press the Back soft key to
return to the Rerange main menu screen.
After pressing OK, the screen will prompt: Apply new 20ma input. This screen prompts the user to apply
the pressure that will become the upper range value. Press the OK soft key to continue. The following
screen will appear. Press Back to escape.
With pressure connections teed with to MFT and the HART device, apply the desired pressure and press
the Select soft key. The MFT will then configure the pressure applied to equal 20 mA.
