Exit Cal: Does not save any new calibration data and returns the user to the Measure Mode.
Restart Cal: Takes the user back to the Recalibration set up screen to begin a new recalibration procedure.
Save Cal: Gives the user a second opportunity to accept the recalibration data.
The user can verify sensor module or mA/V calibration status by pressing the Sensr soft key from the Measure
Mode display. The calibration data will show the sensor ID information and the most recent calibration date.
Other Recalibration Keys and Functions
Adj: Used at the start of the recalibration cycle, this option allows the user to redefine the recalibration target
points. For example: if the first calibration point is a value other than zero, press Adj and enter the desired
target pressure using the Numeric Grid and soft keys. Press Select to go to the next digit. Once you are
satisfied with the new target pressure press Done. The MFT will prompt the user to save this value. Pressing
Yes will change the calibration pressure value for that point. Begin recalibration with the new point designated
on the Apply line. Perform this adjustment on any calibration point you wish to customize.
Abort: Pressing the Abort key will immediately cancel all calibration value changes made to that point, retain
the previous calibration, and return to the Measure Mode.
Next: Takes the user to the next calibration point.
Back: In this mode, Back aborts the calibration procedure and returns the user to the recalibration set-up
screen. The previous calibration data is retained. It does not return the user to the previous screen in the
calibration procedure.
DB-9 CONNECTION PORT
All MFT models are equipped with a standard DB-9 connection for RS-232C communications. The DB-9 provides the
hardware interface to facilitate download / upload operations from a host PC. This connection port facilitates download
of MFT firmware improvements, HART
® Device Object Files (DOFs) and documenting operations. All MFT upgrades
are available via the Meriam Download Site accessible from www.meriam.com. The MFT does not need to be
returned to Meriam for firmware updates or for additional of DOF loading.
Note: Do not use the DB-9 connection port in Hazardous Areas. Use in non-hazardous areas only. See
Intrinsic Safety Control Document in the Appendix for more details on I. S. MFT units.
Note: When using PC without serial ports, use an appropriate USB to Serial adapter such as the Keyspan p/n USA-
19HS.
