MFT 4005 with HART
®
Trims for Pressure and Temperature Transmitters
Overview
The MFT 4005 includes those HART communication functions required for analog and sensor trims for HART
pressure and temperature transmitters. Normally this includes 4 mA trim, 20 mA trim, zero sensor trim, lower sensor
trim, and upper sensor trim although the set can vary from device to device. No HART configuration features are
available in the MFT 4005.
The MFT 4005 provides the same calibration functions, NIST traceable module support and documenting functions as
the MFT 4000 calibrator. In addition, all “Calibrate” key HART functionality present in the VAO1-MFT 4010 HART
calibrator is also available (see the “Calibrate Key” section of this manual for more information). This includes the Quick
Cal and Smart Trim calibration features that enable the user to fully trim HART pressure and temperature transmitters.
Connections to the device under test are the same as those made for the MFT 4010.
Other differences include the following: When the “Quick Menu” key is selected the handheld displays the Smart Trim
menu screen associated with the connected device. When the “HART” key is selected the “List / Show DOFs” screen is
displayed. This allows the user to view the list of HART communication files (DOFs) loaded on the handheld.
Consult the current list of supported pressure and temperature devices at
www.meriam.com . The list is found under the
“Available DOFs” button on the home page. To update the MFT 4005 for new or revised DOFs, consult the “Download
Site Information” section of this manual.
The MFT 4005 model can be field upgraded to the MFT 4010 if full HART communication features are desired after
purchase. Seven day field trials of MFT 4010 functionality are also available with field activation. Contact the MFT
vendor for field trial activation or permanent upgrade pricing.
