Pressing and holding this key will cycle through all available contrast settings. If over-adjusted, simply release key for one second and re-press to change direction of adjustment. After adjusting Contrast, wait at least five (5) seconds before turning unit off to insure storage of new contrast setting.
Soft Keys Soft Keys (unlabled) The four white keys located below the display are the Soft Keys. The specific functions of these keys change depending on the operating mode of the MFT. Current defintions are displayed at the bottom of the LCD display.
HART 3051: PT-3456 Output: 6.5_ Inc mA Dec Next Done Numeric Only Entry Screen Alternative Numeric Entry: When the MFT is in a mode expecting numeric entry from the user, a coded numeric entry system becomes operational. Four of the main keypad buttons (see below) become active for direct number entry. For example, use this feature to enter simulation values for VMA0055, TIO0110, or RIO4000 modules, entering URV or LRV during HART communications, or setting the internal clock.
Measure DISPLAY SCREEN The display screen displays measurements from the modules installed in sensor bays S1, S2, and S3 plus the voltage or current measured by the MFT base unit. Measurements are identified on the display by lines with “S1”, “S2”, and “S3” designators for sensor module bay locations and by “V/I” for voltage or current measurements. The measured values are shown with the corresponding unit of measure. S1: VMA S2: DDN S3: RIO IV: Zero 0.000 0.000 mA PSI No Probe 0.
Pressing the Damp soft key again will remove all damping. This mode is indicated at the top of the LCD display by a “~” symbol. To select “no damping,” toggle the Damp soft key or see the Configuration Settings section of this manual. More This option takes the user to more soft key menu options.

Over Pressurization - Pressure Modules If the MFT pressure sensor is over pressurized above its full-scale pressure range, an “Over range” warning appears on the LCD above the engineering units of the affected sensor. If the applied pressure exceeds 20% of the sensor’s full-scale range, the affected pressure measurement is replaced by an “Over range” warning. If this occurs, immediately release the pressure until the MFT displays a normal reading.
APPLICATIONS Gauge Pressure Calibration The diagram below shows two typical set-ups for calibrating a gauge pressure unit under test. If the process is a liquid, it is vital that the gauge under test be isolated and drained. If liquid enters the xDN module, damage to the sensor can occur. To use an xDN sensor, connect the pressure source to the high-pressure port of the xDN sensor. Vent the low-pressure port to atmosphere.
Differential Pressure Calibration Differential pressure gauges and transmitters can be calibrated using xDN or xGI sensor modules. The following drawing depicts a typical calibration set-up. The units under test should be isolated from the process and drained of liquids if necessary. The low-pressure port of the DP unit under test is vented to atmosphere. Do not connect the low-pressure port of an xDN sensor to the low-pressure port of the DP unit under test.
Vacuum and Absolute Pressure Calibration Vacuum calibrations can be performed with an xDN sensor module by venting the high pressure connection to atmosphere and applying the vacuum to the low pressure connection. Atmospheric pressure is the reference pressure for all vacuum measurements. Absolute pressure calibrations use a xAI sensor module. These sensor modules have an internal absolute zero reference. Simply connect the pressure (or vacuum) source to the single port on the module.
ELECTRICAL CONNECTIONS See Hazardous Area Use Section of this manual for Intrinsically Safe guidelines / restrictions. Milliamp Transmitter The diagram below depicts the proper connection for measuring the current output from a transmitter. The MFT is connected in series with the loop using standard banana jacks. Important: Use the transmitter’s working terminals to measure mA, not the TEST terminals found on some transmitters. Do not use digital communication terminals found on smart transmitters.
FIELD RECALIBRATION All pressure modules and the integral mA / V meter can be recalibrated in the field for zero, span, and linearity. The proper primary standards must be available prior to calibrating the MFT or modules. These standards should meet the accuracy requirements for your company or industry. Meriam follows the guidelines established by ANSI / NCSL Z540-1-1994 which requires that the primary standard be 4 times more accurate than the unit under test.
desired option. Use the Save soft key to choose that option. The display will then return to the main recalibration set-up menu. If you choose not to make any changes to a selected parameter, the Back soft key returns the display to the main recalibration set-up menu without making any changes. Repeat this procedure for each parameter that needs to be changed.
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.

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.
MFT 4010 with HART® Communications Overview The MFT 4010 includes HART communication functions that allow the user to poll, configure and maintain supported HART field device. The MFT 4010 uses a combination of Universal, Common Practice and Device Specific commands to facilitate communication with a field device.
When connecting the MFT 4010 to a loop with a resistive load greater than 250 ohms, the HART jacks may be connected across the loop + and – or to the HART device terminals. Refer to the following diagram for connecting across the loop + and -. Notice the 250 ohm adapter is not needed here. HART® COMMUNICATIONS Initial Screens / Online Mode Upon power up the MFT automatically detects if a field device is connected and attempts to establish HART communications.
If an operating HART device with address zero (0) is connected to the MFC but the “Device 0: Not Found” notification is received, the loop connections to the MFC should be carefully checked. Make sure all connections are correct and secure. Check for shorts, open circuits and multiple grounds. Determine if the loop resistance is greater than 250Ω and less than 1100Ωs. If less than 250 Ω then use the supplied 250 Ω load resistor in series with the loop (see diagram HART Connections section).

The module is set up to allow calibration using precision 10 Ω, 100 Ω, or 1000 Ω resistors rated for a total tolerance of 10 PPM. The user selects the best resistor value for the types of RTDs the RIO4000 will be used to calibrate. One connector (P/N A900442-00026) is needed for each precision resistor used.
Module Only cal can also be performed using a User Cable (p/n A900028-90500) and a precision resistor. When the User Cable is connected to the RIO4000, the RIO User Select Screen is displayed. The user can select the 10 Ω, 100 Ω, or 1000 Ω precision resistor options from the list and proceed as above. 3.
When the Error value is within acceptable limits, press the Next soft key. This moves the calibration procedure to the next calibration point. Repeat the procedure outlined above until all points are complete; when the final recalibration point is acceptable, press Next to store the data. After completion of the calibration process for 1, 3, 5, or 9 points, the MFT will inquire if the cal data should be saved. Select Yes to accept the recalibration data or No for other options.
