MFT 4000 SERIES OVERVIEW
The MFT 4000 Multi-Function Tester (MFT) is a modular calibrator with three sensor bays accommodating up to three
independent pressure, temperature or special function modules. The base MFT incorporates a voltage and current
meter, several keys for user interface and will display up to four measurements simultaneously. The MFT 4005 adds
HART trim capabilities for one-tool calibration of HART pressure and temperature devices. The MFT 4010 adds full
HART communication capability to the same handheld base unit for greater flexibility and versatility in commissioning,
reconfiguring, and maintaining HART field devices including analytic, flow, level, pressure, temperature, and valve
categories.
Note: For Intrinsically Safe MFT models, consult the Hazardous Area Use section of this manual for specific
details on use of approved MFTs and applicable restrictions.
KEYPAD OVERVIEW
The following is an overview of the MFT 4000 series keypad operations. The MFT keypad has three basic key types
(the functions of each are described below): Single function keys, dual-function keys, and soft keys. Single function
keys control a dedicated MFT function. Dual-function keys, through the use of the Function key, control two
separate functions. Soft key functions change depending on the operating mode. Their definitions are displayed at
the bottom of the LCD, just above each white soft key.
Single Function Keys
On/Off
Pressing the On/Off key powers up the MFT. As the unit powers up, it performs an internal diagnostic check
of its systems. Any abnormalities are posted on the display. The unit will briefly display the MFT model
number and the installed sensor module ranges and bay locations (S1, S2, or S3) before the unit enters the
Measure Mode.
Back Light
The MFT has a back light feature with two light intensities. Toggle this key from Off to Low intensity back light
to high intensity to Off again. A back light off timer is available under the Settings key to help conserve
battery life.
Measure Mode
Pressing the Measure Mode button will instantly return the unit to measure mode from any menu or sub-
menu. Measure will appear on the upper left of the display.
