MFT 4000 SERIES OVERVIEW

LCD

Single Function Keys

AC Adaptor Jack

HART Jacks

DB-9 RS232 Connection

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.

Module Bays (3)

Soft Keys

Dual Function Keys

Voltage / mA Jacks

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 submenu. Measure will appear on the upper left of the display.

Display Contrast

This key allows the user to adjust the contrast of the LCD display for ambient conditions or user preferences. 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.

Function

The Function key is pressed to access the functions labeled in blue on the dual-function keys. Pressing the Function key will allow the user to access and/or alter the corresponding properties. Function remains on until it is depressed again. When the Function key is active, an up arrow (  ) will appear at the top of the display to the left of the battery power or AC wall plug icon.

Dual Function Keys

S1 Units

The S1 Units key changes the engineering units for the module in sensor bay 1. The Function key must be active before the units can be changed. When numeric entry is anticipated by the MFT, this key can be used to toggle from 1 to 2 to 3 and back to 1 for entry purposes.

HART (Active only with MFT 4010)

The HART key puts the MFT 4010 series calibrator into its HART Communications mode and initiates communications via the HART connections at the bottom of the MFT.

Units Sensor2

The S2 Units key changes the engineering units for the module in sensor bay 2. The Function key must be active before the units can be changed. When numeric entry is anticipated by the MFT, this key can be used to toggle from 4 to 5 to 6 and back to 4 for entry purposes.

Settings Provides access to the settings menu. This menu shows the current unit settings and allows the user to customize MFT settings. See Settings section for more details.

Units Sensor3

The S3 Units key changes the engineering units for the module in sensor bay 3. The Function key must be active before the units can be changed. When numeric entry is anticipated by the MFT, this key can be used to toggle from 7 to 8 to 9 and back to 7 for entry purposes.

Quick Menu (Active only with MFT 4010)

This key provides a list of frequently used HART configuration and maintenance function menus. User can quickly scroll to any desired menu. Also, pressing and holding this key from Measure Mode will enter the HART Offline Menu.

Units mA / V

Toggles between voltage, current (mA), and off display for the integral voltage and current meter. This measurement is designated by “V/I” on the display. When numeric entry is anticipated by the MFT, this key can be used to toggle from 0 to (decimal point) to (negative sign) and back to 0 for entry purposes.

Calibrate

This key enters the MFT into calibration & documentation mode for local indicators, conventional transmitters, HART transmitters, Fieldbus transmitters, and mA loop calibrations.

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.

Alphanumeric / Symbol Entry

For MFT applications requiring alpha, numeric, and symbol entry (examples: tagging or messaging), the MFT uses three display grids, the FUNCTION key to change from one grid to another, and four soft keys used for cursor movement and selection of characters and text. MFT and HART communication functions that require alpha and numeric entry automatically call up the appropriate grid and make the other grids accessible using the FUNCTION key. Row and Column soft keys are used to move the flashing cursor through the displayed grid. The Select soft key enters the indicated character in the text line and the Done soft key accepts the displayed text line and returns the MFT to service.

Character grids are provided for numeric, alpha, and symbol characters to permit complete editing of text fields. Each grid includes back space (), forward space (), delete (del) and space (spc) operators to accommodate text editing needs.

User Interface

The displays shown below illustrate the alphanumeric entry grids and soft key functions. Pressing the MFT’s FUNCTION key changes the display from one grid to another allowing text messages to be developed using all three grids when needed.

Row Col Select Done

Alpha entry grid Numeric entry grid

When using any character grid, pressing Row or Col keys will move the flashing cursor one character across or down the grid. Pressing and holding the Row or Col key causes the cursor to advance down or across, respectively, at a regular rate. Releasing the key when the cursor is under the desired character stops the cursor movement and allows the selection of the character using the Select key. Press the Done soft key when the character string is completed to enter the string and continue MFT operations.

Numeric Entry: Many HART functions require only numeric entry. For these functions the MFT uses an Increment and Decrement scheme to change the input field one place at a time. Press the Inc / Dec soft keys

to move through a scroll of -, . , 0, 1…9, and space until the desired value is displayed. Press the Next soft key to enter that value and advance to the next place in the input field. Repeat as necessary. Press the Done soft key to end the numeric entry session.

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. Use the Å and Æ soft keys to move the cursor to the desired location. For a number 3, press the “S1 Units” key three times. For an 8, press the “S3 Units” key twice.

MEASURE MODE

After the MFT performs its power up diagnostics and displays the model number and sensor data, it defaults to the

Measure Mode. The word Measure appears on the upper left of the display, confirming this mode is active. The soft

key definitions in this mode are directed toward measurement and information functions.

NOTE: Power icons may temporarily disappear during certain HART Communication operations

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.

Measured values displayed here are subject to the MFT’s Smart Damp system unless otherwise changed using the Damp Soft Key (see details in the section below). Smart Damp eliminates electronic circuit noise but does not slow the display of changes in measured signal. The result is a very stable but responsive digital display of measured values.

SOFT KEY MENU OPTIONS

On the bottom of the main menu screen in Measure Mode the following definitions are displayed just above the white soft keys. These definitions indicate the function of each soft key.

Zero Mn/Max Damp More

Zero

Zeros the installed sensor modules, if applicable, and integral mA/Volts meter. The LCD will display “Zero in Progress” as this function is carried out. Sensors should be zeroed prior to making measurements to provide an accurate zero reference. Make sure that no physical signal is applied to the MFT when performing this function. To prevent unintentional zero offset, a Zero command will be aborted if more than ±5% of full scale signal is being measured by any MFT sensor. Absolute pressure modules cannot be zeroed until the applied pressure is less than 5% of full scale. This prevents the accidental corruption of the absolute zero reference essential to absolute pressure module performance.

Mn/Max

The Mn/Max key allows the user to display the minimum and maximum measured value each sensor has measured since this function was activated. The min/max values are displayed below the normal pressure or V/mA reading. To reset the Mn/Max function, toggle the Mn/Max key once for off and again to restart.

Damp

The MFTs default damping mode is Smart Damping for the most stable yet responsive display of measured values. The Damp soft key lets the user choose exponential or no damping for the duration of the On cycle.

To change the damping mode, toggle the Damp soft key or see the Configuration Settings section of this manual.

Pressing the Damp soft key once from Measure Mode initiates an exponential averaging function over a user selectable time constant. This function smoothes the peaks and valleys of pulsating measurements for a more stable display. A “D” symbol appears in the top line of the LCD display when exponential Damping is activated. To change the time setting for exponential Damping refer to the MFT Configuration Settings

section of this manual.

Measure Mode Main Screen

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.

This option takes the user to more soft key menu options. After pressing More from the menu options above, the following soft key options are made available:

Hold Sensr Rcal More

Hold

Pressing the Hold button freezes the measurements on the display to allow convenient reading or transcription of data. An “H” symbol appears on the top of the LCD display when this feature is active. Pressing Hold again returns the MFT to normal Measure Mode.

Sensr

Pressing the Sensr key provides detailed information about the installed modules. The first screen provides information pertaining to the sensor in module bay 1, including the sensor model, serial number, and the date the unit was last calibrated. Pressing Next consecutively scrolls through the remaining installed sensors, then the electrical inputs, and finally the MFT itself. The MFT information provides the model number of the unit, the serial number, firmware revision, and the date the firmware was installed.

Pressing Next after scrolling through all available information returns the user to the Measure Mode screen.

GENERAL OPERATION

Sensor Installation/Removal

To install a new sensor module into a sensor bay, make sure the spring-loaded sensor lock is facing toward the

rear of the MFT. Depress the sensor lock until the base of the sensor module passes into the sensor bay. Push module into bay until it locks into place.

Once installed, the MFT will immediately read the data from the sensor and load it into the system. The display will briefly show what sensor has been installed. The engineering units that were previously assigned to that sensor module will automatically be displayed. Sensor modules may be installed in any sensor bay.

To remove a sensor module from a sensor bay, depress the spring-loaded sensor lock corresponding to the module you wish to remove. The sensor lock needs to be depressed so that it clears the MFT housing. While pressing down on the sensor lock, simultaneously pull upward on the module. A pen or small screwdriver may be used to depress the sensor lock far enough to clear the housing.

Once a sensor module is removed from a bay, the display will clear that sensor’s information from the display screen.

Note: Modules should be removed or installed with the MFT base unit in the Off state. For intrinsically safe versions installation or removal must be done in a non-hazardous environment only. See Hazardous Area Use section for more details.

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. Although pressures are displayed up to 20% over full-scale range, specified accuracy is guaranteed for full-scale range only.

GI (Gauge Isolated) and xAI (Absolute Isolated) Modules are capable of withstanding up to 2x the sensor

range without sustaining damage.

DN (Differential Non-Isolated) Modules are capable of withstanding up to 2x the sensor range when

pressurized on the high side only. When pressure is applied to both the high and low side sim ultaneously, all

DN sensors have a 150 PSI pressure limit.

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 x 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.

When calibrating a gauge pressure unit using an x the xGI sensor does not have an external vent to atmosphere.

In some cases the actual process may be used as the pressure source for calibration. If you choose to use the process to perform the calibration, make sure the process is compatible with the sensor used, and that it provides a stable pressure. If your process has a fluctuating or pulsating pressure, use of an external pressure source is recommended to ensure the accuracy of your measurements and calibration.

Differential Pressure Calibration

Differential pressure gauges and transmitters can be calibrated using x 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 x dead end connection can cause errors due to the expansion or contraction of trapped gas as a function of temperature change.

Meriam does not recommend using process pressure as the pressure source for DP pressure device calibration. Errors in measurement and calibration can easily creep in if the pressure source is unstable. In addition, x used properly. Sensor damage can occur if more than 15 PSI is applied to the high or low side of an xDN0020 or x

Additional DP Application Information

In addition to reading gauge pressures, the MFT can also be used to measure the pressure drop across a device in a pressurized pipe. Examples include measuring the differential pressure across positive displacement meters, filters, orifice plates or valves. Process compatibility and pressure ranges of the sensor modules need to be considered for each application.

A three valve equalizing manifold or push-to-read equalizing valve should be used to avoid damaging x for each type of valve manifold.

3-Valve Manifold: Make sure all shut-off valves are closed. Connect to the process. Slowly open the equalizing valve. Slowly open the high pressure valve and then the low pressure valve. Close the equalizing valve and take the measurement. Reverse the process to disconnect.

Push-to-read valve: Connect to the process. Open shut off valves. Push the push-to-read plunger to take the reading.

DN sensors. Follow the specific operating procedure

Vacuum and Absolute Pressure Calibration

Vacuum calibrations can be performed with an x 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 x reference. Simply connect the pressure (or vacuum) source to the single port on the module.

The following diagram shows the connection for both a vacuum and an absolute pressure measurement. If the process maintains a stable pressure, it can be used as the pressure source in some calibrations. Process compatibility and pressure ranges of the sensor modules need to be considered for each application.

Voltage Transducer

The following diagram depicts the correct set-up for transducer calibrations.

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.

For pressure sensor modules up to 200 PSI, Meriam recommends a ±0.0015% of reading deadweight tester for optimal accuracy. For sensors 200 PSI and above, a ±0.0030% of reading deadweight tester is recommended. If calibrating using inches of water units, be sure to match the reference temperature of water in both devices.

The TIO0110 thermocouple module field recalibration supports one (1) point at 0.00 ºC. See the TIO0110 T/C Measure & Simulation section in the Appendix of this manual for more details.

The RIO4000 RTD module field recalibration supports Module Only recalibration using precision resistors and Module + Probe recalibration using a temperature bath or a dry block temperature tester. See the RIO4000 Measure & Simulation section in the Appendix of this manual for more details.

The VMA0055 mA / V module does not have field recalibration support. Contact the manufacturer to return out of tolerance VMA0055 modules for service and recalibration.

To enter Field Recalibration mode from the Measure Mode display, press the More soft key, then press the Rcal soft key. This will access the Field Recal Setup screen.

Units: Allows the user to choose the engineering units to calibrate in. Meriam recommends the calibration be

performed in the default units of the subject sensor. For example: an x water referenced to 20º Celsius should be calibrated using a deadweight tester with the same units and temperature reference. Other engineering units or reference temperatures may be used but great care in units and temperature reference conversion must be used to achieve accurate calibration results.

Points: This option allows the user to select the number of calibration points desired from pressure modules. The example above would use 3 calibration points; 0%, 50%, and 100% of the full range of the sensor. The user may select 3, 5, or 9 point calibrations if desired for pressure modules.

Repeat this procedure for each parameter that needs to be changed.

Procedure - Field Recalibration

Once all of the desired parameters and options have been set, scroll Down to Start on the main recalibration menu and press the Select soft key. This takes you into the recalibration display.

Field Recal

The recalibration screen shown above provides the following information:

Cal Point: This is the target calibration point expressed as a percentage of the sensor module full scale pressure.

The next line shows the sensor bay location or analog sensor being calibrated (S1, S2, S3, V, or mA). The pressure applied by the user is also shown in the engineering units previously selected.

Error: Is the percentage error between the applied calibration pressure and the recalibration target pressure for the recalibration point (Apply value). + and – indicates whether the error is above or below the recalibration target pressure (Apply value).

Apply: This is the recalibration target pressure the MFT assigns based on the number of calibration points set in the recalibration set-up menu.

Make sure your pressure source and calibration standard are properly connected to the sensor module under test. Connections must be leak free. The first recalibration target pressure is normally zero, so the first point should have all zeros. (As shown in example above—See section Adj for other options). Adjust the pressure source until the pressure you are applying matches the Apply pressure & the Error percentage goes to zero.

If the error percentage is not zero, attempt to adjust the applied pressure until the unit reads zero. If zero error can’t be achieved, a small error percentage within the accuracy of the unit under test or error within company accuracy guidelines may be acceptable.

When the error % is within acceptable limits, press the Next soft key. This moves the unit to the next calibration point. Repeat the procedure outlined above. When the final recalibration point is set, press Next to store the data.

After completion of the calibration process for 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.

DOCUMENTING CALIBRATION RESULTS Overview

The MFT 4000 Series of multi-function calibrators come with standard documenting capability. Documenting enables the MFT to work with manually created or DMS generated “From PC” or “stored” calibration procedures for use with specific field devices, save As found results, trim the device, save the As left results, view saved calibration results and upload saved results to Meriam’s Device Management System (DMS). MFTs with the full HART option (MFT 4010) also have the ability to save configurations to memory and upload those configurations to DMS to provide a complete history on the field device. For more information on DMS, please go to www.meriam.com or contact Meriam at (216) 281-1100.

The MFT 4000, MFT 4005, and MFT 4010 include documenting to enable the user to document Manual Calibration Procedures, From PC (Stored) Calibration Procedures and Template Calibration Procedures. (See the Applications section of this manual for typical calibration connection diagrams). Typically, Manual, From PC, and Template procedures require an As Found calibration check, trimming operations to correct an out-of-calibration condition, and an As Left calibration check. MFTs with the documentation capability provide this functionality. The MFT can measure or simulate the input to the device under test as well as measure the output of the device under test. It also supports the keyed entry of the device under test’s output values to document calibrations of local Indicators, fieldbus devices, and loop tests as well.

Manual Calibration Procedures are performed by varying the input signal (e.g. pressure for a pressure transmitter), allowing the input to stabilize, and saving the measurements made by the MFT to memory. Manual calibrations can be defined on the fly by the technician as the variable to the unit under test is applied, or the MFT can be used in advance of the calibration to create a manual calibration procedure in the field. If the device under test is a HART device, the AO and Pres (PV) obtained via HART communication will also be saved. If the device is a local indicator or fieldbus device, or if a current loop is being calibrated, the user keys in the device output value so that it can be saved along with the MFT measured or simulated value. The number of calibration points saved per manual calibration is up to the user (maximum of 255 per device).

From PC (Stored) Calibration Procedures prompt the user for each input signal according to the predefined procedure stored in the MFT memory. Stored procedures are set up in the Meriam Device Management System software and assigned to device tag numbers there. The procedures are then downloaded to the MFT. Conventional and HART transmitters can both be supported by “From PC” procedures as can local indicators, fieldbus devices, and loop calibrations. When calibrations become due, the DMS operator downloads the list of tag or loop numbers and their associated procedures to the MFT. The technician then takes the MFT to the field, makes the needed connections to the device of interest, looks up the “From PC” stored procedure for the device under test, and begins the calibration. The MFT guides the user through the complete procedure and electronically documents the results.

Template Calibration Procedures are created on the MFT and are available for recall and reuse at any time. One pressure template, one temperature template and one switch template are available for setup and saving to memory. Templates are useful for repetitive calibrations on similarly configured field devices of the same type. Template setup follows the Create Manual Calibration Procedures menus.

The dedicated MFT calibration memory can save up to 100 calibration result files with up to 21 As Found and 21 As Left points with header information including Tag, S/N, LRV, URV, date and time.

Entering Calibration Documentation Mode

Press the Calibrate key to setup the MFT to document the calibration of HART or conventional devices. The following screen will appear (see the Calibrate Key section earlier in this manual for more details):

Begin Calibration: after properly setting the Procedure, Device Out and Cal Type options, select Begin

Calibration to initiate a calibration documenting session.

Procedure: Select to set up the MFT for Manual Calibration, From PC (Stored) Calibration Procedure or

Template Calibration Procedures. The following screen will appear:

Device Out: Select to set up the MFT for calibration of HART devices (HART mA or HART PV multidrop loops),

conventional devices, or for entry of the device under test’s local indication (local indicators or Fieldbus device readings). The following screen will appear:

Cal Type: This option allows the user to select and set up the type of calibration desired. Cal Type menu provides the user with a list of supported calibration types to choose from. Meas/Sim menu allows the user to select the needed MFT operation for the device under test’s input. Measure menu allows the user to select the needed MFT operation for the device under test’s output. See the Calibrate Key section earlier in this manual for more information. A sample of the Cal Type screen is shown below.

Calibrate Key Main Menu Screen

Press the Back soft key when satisfied with the settings or if you choose not to make any changes. The MFT will then return to the Calibrate key main menu screen.

Manual Calibrations and Documentation Selecting Procedure: Manual and Device Out: Conv and pressing Begin Calibration causes the following screens to appear:

Enter the necessary or desired information or select options from supplied menus as needed to set up a manual calibration right on the MFT. Be sure to target the Meas/Sim menu line to the Sensor bay location (S1, S2, or S3) where the reference module for the calibration is located. Meas/Sim refers to the action needed to provide measurement or simulation for the device under test’s input. Example 1: Pressure transmitter calibration requires external pressure to be applied to the Sensor Module and the device under test simultaneously, so select the Sx location for the Pressure module needed to measure the applied pressure. Example 2: RTD transmitter calibration requires simulation of RTD signal to the device under test so select the Sx location for the RIO4000 measure and simulation module.

Review the second page of Manual Calibration Input information by selecting the <More> menu option on the first page. This sets up the MFT to Measure the output of the device under test with the appropriate sensor. Correct any information necessary.

Once satisfied, move the arrow to Begin Calibration and press the Select soft key. If problems exist in the setup, the MFT will normally provide guidance to correct them. For example, if the user forgot to input the URV, the message “URV must be > LRV” will appear and the cursor will be pointed to the URV menu line. If the user pointed the Meas/Sim menu to an RIO4000 module for a Cal Type “P”, the message “Module / Type Mismatch!”

From PC (Stored) Calibration Procedures and Documentation The Stored procedure option is only available when the MFT is used in conjunction with Meriam DMS software or other compatible FCINTF software programs. The Field Calibrator Interface (FCINTF) specification has been implemented as the MFTs Interface for receiving and transmitting calibration data. Compatible asset management software programs should be able to transmit assigned calibration procedures to MFT. They should also be able to receive calibration results back from the MFT.

Stored procedures are developed and assigned to a tag number in the DMS software. Then they can be downloaded into MFT memory for later use in the field. The downloaded information includes tag number, LRV, URV, units, transfer function, serial number, calibration procedure, allowable test point error percentage, maximum allowable error percentage and adjust-to error percentage. All information is then available to the MFT user in the field for calibration activities. See the DMS User’s Manual for more details.

To start a From PC (Stored) Procedure Calibration, press the MFTs Calibrate key, set up the MFT for From PC Procedure using the Procedure, Device Out, and Cal Type menu options described earlier, and then Select the Begin Calibration option. The following screen will appear allowing the user to select the tag number of interest.

Arrow to and Select the desired tag number.

When the MFT has been set up for HART mA calibration, the MFT will poll the connected device and confirm the tag number match between the device and the From PC stored procedure. If a tag number mismatch is detected, the MFT display will advise “Device mismatch, continue with this device?” Pressing the No soft key aborts the procedure. Pressing the Yes soft key enables the use of the stored procedure with the mismatched device tag and saves the calibration data under the connected device’s tag number (this information is obtained over the HART connection).

Loop Test Calibration Procedures and Documentation - Manual

Loop Test allows the user to choose a calibration procedure from a list of commonly checked loop output values or to input a custom loop calibration procedure. This function can be used with conventional or HART devices with current (mA) output. For conventional devices, the MFT’s VMA0055 module is used on the loop to simulate a transmitter output to the loop (loop is externally powered for this test with greater than 20 mA available on the loop). For HART devices, the MFT 4010 sends HART commands to “fix” the device’s analog output to the selected values (regardless of process variable value). In either case, the user keys in the value of the loop received by the control room, or read by a receiving device, to document the loop performance.

Enter the Loop Test Calibration function by pressing the Calibrate Key from the MFT’s Measure Mode and then set up the Procedure (Manual or From PC as appropriate), Device Out (Conv or (Loop Test) menu options as described in the Calibrate Key section of this manual.

Once Cal Type is set to Loop Test then VMA Sim / IV Meas should automatically be set as well. When satisfied with the set up, Select the Begin Calibration menu option. On the resulting screen, shown at left below,

Loop Calibration Procedures and Documentation – From PC (Stored)

Loop calibration procedure setup features similar to those described in the Loop Calibrations and Documentation section above are available in the Meriam Device Management System. This allows the user to define loop calibrations and assign calibration procedures to specific loop tag numbers in the DMS database. DMS tracks calibration schedules and alerts the user when loop calibrations are coming due. DMS will download loop calibration procedures to a documenting MFT for use in the field. For conventional devices, the VMA0055 module is used to simulate a transmitter on the loop to be tested. For HART devices, the MFT 4010 sends the HART commands needed to fix the device output to the procedure value. Once the loop calibration has been completed, the results can be uploaded to DMS where they are stored by their loop tag numbers for review and future reference.

Many of the MFT screens shown in the Loop Calibration and Documentation – Manual section above are reused in the Stored procedure method.

Switch Test Calibration Procedures and Documentation – Manual

Switch Test procedures allow the MFT to test and document the set point, reset point and deadband of a switch. Supported switch types include pressure, temperature and level (head type) switches.

cursor arrow down to the Cal Type line and pressing the Select soft key. You will also want to set up the Meas/Sim line and the Measure line for the specific switch test desired. Meas/Sim refers to the action the MFT needs to perform for the input to the device under test (this could be Measure a pressure or temperature to a device under test or Simulate a RTD or T/C value to a device under test). Measure refers to the action the MFT needs to perform for the output from the device under test (for switches this will usually be measuring the switch circuit voltage on the MFT’s IV line). See the Calibrate Key section of this manual for more details.

Review Switch Test Results

Once the switch test is complete, select the Next soft key to review the results. If the test needs to be

repeated, select the Abort soft key and restart the test. To save the As Found switch tests results,

select the Save soft key from the Review Switch Test Results screen. The user will be given a

chance to save the As Found data to As Left data, to Trim the switch set point (MFT display will show

switch input and switch state while trimming operations are executed), to start the As Left

documenting session (after Trim operations are completed) or to View the As Found Results.

Important Note: For Pressure Switch tests, it is very important to increase pressure slowly as the set

point or reset point is approached. Quickly increasing and decreasing the pressure reduces the

accuracy of the captured set point and reset points. Similarly, for simulating RTD or TC signals be

sure to set the Ramp Time long enough for the LRV / URV range to insure accurate capture of set

point and reset point values. The switch test software allows the user to discard the As Found or As

Left results as many times as needed during the documenting session. Users can use this feature to

determine whether or not a good set of data has been captured by comparing consecutive test results

and then saving the results when satisfied.

Switch Test Calibration Procedures and Documentation – From PC (Stored)

Switch Test calibration procedure setup features similar to those described in the Switch Test Calibrations and Documentation section above are available in the Meriam Device Management System. This allows the user to define Switch Test calibrations and assign calibration procedures to specific switch device tag numbers in the DMS database. DMS tracks calibration schedules and alerts the user when Switch Test calibrations are coming due. DMS will download Switch Test calibration procedures to a documenting MFT for use in the field. The VMA0055 module is normally used to wet the switch circuit to be tested although external wetting by a VDC source of 50 VDC or less is also supported. Once a Switch Test calibration has been completed, the results can be uploaded to DMS where they are stored by their tag number(s) for review and future reference.

Many of the MFT screens shown in the Switch Test Calibration and Documentation – Manual section above are reused in the Stored procedure method.

Deleting Files and Clearing Documentation Memory

Deleting Documentation Files

Individual calibration procedure / result files can be deleted from the MFT using the Del soft key found on the View Calibration Results Screen. This screen is accessed by pressing the MFTs Calibrate key (see the Calibrate Key section of this manual for more details). The Del key removes the record from the display (Deleted shown instead) but it does not clear the memory space.

Clearing Documentation Memory To clear all calibration procedure / result files, Select the Clear Cal Memory menu option under the MFTs Calibrate key (see the Calibrate Key section of this manual for more details). A delete confirmation screen is

provided to prevent unintended clearing of all documentation files.

An alternate way to clear documentation memory is to connect the MFT to Meriam DMS and use the Clear MFT Calibration Data function. See the DMS User’s Manual for more details.

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 “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 list is found under the

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.

MFT 4010 with HART

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. Combining HART ability with the modular calibrator means that technicians can use one device to perform device analog output trim adjustments (4 and 20 mA), trim the sensor, re-configure the field device, or poll a device for basic information.

The MFT 4010 will communicate with any HART device through Universal and Common Practice Commands using the standard Generic DOF (Device Object File) but must have the DOF for a specific HART device installed before it can execute Device Specific Commands. Consult the list of available DOFs at www.meriam.com “Available DOFs” button for an up to date list of HART devices.

HART COMMANDS

Three HART command types are used by the MFT 4010 to communicate with HART field devices. First,

Universal Commands are primarily used to identify a field device by its model number and tag number and to

read process data from the device. This communication is often referred to as “polling”. The MFT 4010 can poll

any Hart Device. Second, Common Practice Commands are used for calibration and maintenance functions

that are common to many devices. An example of this would be to trim or adjust the analog output. Third,

Device Specific Commands are used to handle functions that are unique to a particular device or manufacturer.

Examples of these commands include sensor zero, sensor trim, calibration curve characterization, density inputs required for calculations made by the HART device or other configuration functions unique to the specific device.

HART CONNECTIONS

HART connections are made using the two standard banana jacks (3/4” center) located at the bottom of the MFT 4010. Refer to the following diagram. Polarity is not a concern for HART connections so both jack collars are black. Meriam supplies a test lead kit (P/N A36744) complete with standard connector for each model MFT

4010.

For low load loops (less than 250 ohm), a 250 ohm resistor will need to be added to insure reliable HART communications. Meriam supplies a 250 ohm load resistor in the form of a standard adaptor (P/N A36821). Refer to the following diagram for details on connecting the adapter. This method requires the loop be opened in order to make the necessary connections.

Communications

MFT 4010 with HART®

Electrical connections are shrouded standard banana jacks (3/4” center) for 50 mA/volts measurements. HART Since HART is polarity independent, the HART jacks both have black collars.

. Click on the

loop connections are also standard banana jacks.

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. When a device with address zero is found, the MFT provides feedback to the user and starts the initial HART display for the connected device. See an example of Online Mode below.

When no device connection is detected, the MFT enters the MFT Main navigation screen and the message Device 0: Not Found is displayed. Upon selecting the “1 Online Setup” option, the MFT checks again for Device address 0 and if not found displays the MFT Multidrop / Retry 0 screen. This screen allows selection of either of three options: launch Multidrop poll by selecting the Multi soft key, retry Device 0 communication after re-checking physical connections to the device by the selecting Retry soft key, or to Exit to Offline mode by selecting the Exit soft key.

Communications Trouble Shooting

If an operating HART device is connected to the MFC but the “Device 0: Not Found” notification is received, a Multidrop Poll may be executed to determine if the connected device has a non-zero address. Select Online Setup from the MFC Main navigation screen and then select the Multi soft key to initiate the Multidrop poll. If the “No Devices Found” message is received, then the loop connections to the MFC should be carefully checked.

Support

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 1100s. If less than 250 Ω then use the supplied 250 Ω load resistor in series with the loop (see diagram HART Connections section).

If communication is still not established, check the List / Show DOFs menu under Offline Menu. Check the list for the presence of the “Generic” DOF under the manufacturer name “Meriam.” If “Generic” is found, then HART communication is possible when the device is properly wired and connected to the MFC (see connection troubleshooting details above).

When the message “Generic” is displayed after connecting to a HART device there are two possible causes:

1) No device specific DOF for that device is currently installed in MFC memory. Check for availability of the DOF needed by going to the Available DOFs site at www.meriam.com/customers/past.asp

. Sort the list by clicking on

any column header. For download instructions, see the DOF / Firmware Download Site section of this manual.

2) The connected HART device supports only HART Universal and Common Practice commands (i.e. generic commands). There are several such devices on the market, particularly level type devices.

Multidrop Poll (addresses 1 – 15)

To initiate a Multidrop Poll, select the Online Setup option from the MFT Main screen when the Device 0: Not Found message is displayed. Then select Multi soft key from the MFT Multidrop / Retry 0 screen. This function polls for all non-zero addresses (1 – 15). Located addresses are listed on the display as the remaining addresses are checked.

When polling is complete, or upon pressing Stop after the address of interest is found, use the soft key controls to select the address of interest. The initial HART menu for the device selected will then be displayed for use.

Digital Poll (addresses 0 – 15)

Digital Polling is a special feature accessible through the MFT’s Main navigation screen and the Cfg soft key. Press the Cfg soft key and then select the “2 Applications” menu option. Select the “1 Digital Poll” menu option to launch a polling operation that includes address 0 and ends with address 15. All addresses on the loop will be displayed on the MFT’s screen. The address of interest can be selected from the list to launch HART communication with that device. Digital Poll can only be launched from this location in the handheld’s menu structure.

Manual Launch of Device 0 Poll

When the message Device 0: *On-line* is displayed on the MFT Main navigation screen, selecting Online Setup will launch HART communication with the device. The message indicates that a HART device with address 0 has been detected at the HART connection and the MFT is standing by to initiate communications. The Device 0: *On-line* message is shown 1) if a physical connection is made to a HART device after the MFT power is turned on or 2) if the user exits from a HART communication session without disconnecting the lead wire by using the soft key controls provided.

Cloning HART Devices

Cloning an existing HART device configuration can be very useful for configuring other devices of the same type. The MFT provides two options suitable for cloning.

Copy configuration and send to new device

Connect to the HART device of interest and select the Save option to save a copy of the configuration. Connect to the new device of same manufacturer and model and select the Send option. The screen will show all saved configurations by tag number. Move the cursor to the desired configuration and press the Select soft key. Verify the configuration is the one desired by reviewing the displayed details. When satisfied press the Select soft key to send this configuration to the connected device. Now use normal HART communication menus to replace the old tag number sent with the new tag number and to correct any other parameter(s) as necessary.

Saving Configurations for Multivariable HART Devices

Multivariable HART devices permit the user to select one Primary Variable (PV) from its device variables list and assign the analog output to the selected PV. These device variables may be measured or calculated by the device (e.g. mass flow, density, temperature, viscosity, etc… for a coriolis mass flow meter). For some users saving only the PV’s HART parameters may be satisfactory. However, it may be useful in multivariable applications to save the parameters of the secondary, tertiary, and other variables in addition to the PV parameters. The MFT allows the user to save only the PV parameters or to save the parameters of all variables by sequentially changing each variable to PV and saving the respective parameter sets. This is accomplished with the PV Prompt setting which can be found under the Cfg soft key on the Current Settings screen’s Lockout menu option. Enabling this prompt causes the MFT to display the following question when a HART multivariable device is detected.

“Multi variable device, allow PV changes? Yes / No”

MFT units are shipped from the factory with the PV Prompt setting defaulted to disable and locked out with the factory lockout code of “321”. With the default set to disable, the MFT will only save the PV parameters for the current PV assignment of the multivariable device. To enable all multivariable device parameters to be saved to the MFT during a Save command, simply unlock the MFT settings (see the procedure in the “MFT Configurations Settings” section earlier in this manual) and reset PV prompt to Enable. This setting will cause the MFT to first save the PV parameters for the current PV assignment. The user will them be prompted to allow the MFT to change the PV assignments to perform a save of the next variable. The MFT continues in this manner until all variable parameters have been saved; then the MFT resets the PV to the original variable assignment.

More Status Message

HART device events (diagnostic flags) cause the MFT 4010 to display a “More Status Message” at the bottom of the display. This message is a notice to the user that one or more diagnostic warnings are available in the Review Status menu option of the connected device. Upon receipt of this message, enter the HART mode and select Detailed Setup / Diagnostics – Service / Test – Status / View Status to retrieve the diagnostic information.

HART OFFLINE MODE

HART Offline Mode comes up automatically if communications with a HART device are not established, and Multidrop Polling was declined, stopped, or aborted.

A faster way to access HART Offline Mode is available by pushing and holding the "Quick Menu" key for a few seconds. The screen at right will appear:

Scaled D/A Trim: Scaled D/A Trim is a feature that allows HART output using a different analog scale to measure the loop current. For example, an I/O resistor is commonly placed in series with the two wire 4-20 mA loop to convert the current signal into a voltage signal for use by the DCS. By measuring the voltage across the I/O resistor, the loop current value can be obtained by dividing the voltage by the resistor value. Scaled D/A Trim allows the user to enter this voltage directly instead of having to convert it into the actual current value. During the trim function, the transmitter output is set to a fixed output (first 4 mA and then 20 mA). The user is prompted to enter the meter reading using the analog scale selected by the user. The transmitter D/A calibration trim is then adjusted to obtain the correct meter reading. The resulting calibrated loop delivers a precision voltage signal to the DCS.

To use Scaled D/A Trim, first make connections to the HART transmitter of interest and press the HART key. Once communication is established, select the Device Configuration option on the first display, then Diagnostics, then Calibrate, then Analog Trim and finally Scaled D/A Trim (these menu paths and titles may vary with HART device). The screen will prompt: “Loop should be removed from automatic control.” 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. Use the Select soft key to accept OK. Press the Abrt (Abort) soft key to return to the previous screen without making changes and without taking the device offline.

If OK is selected, the following display will appear:

6.0 and a message will be displayed to “connect reference meter.” An accurate reference multimeter should be connected across the I/O resistor at this point. Select the OK menu option once this is done. The message “Setting field device output to 4 mA” will be displayed. Selecting the OK menu option causes the MFT to send the AO fixed command for device output of 4 mA. The next display asks the user to “Enter meter value” as read from the multimeter display. Use the Numeric Grid and soft keys to enter this value. Press Done when finished and the following screen is displayed.

If the meter now reads the correct scale value for 4 mA output, Select Yes to continue on to “Setting field device output to 20mA.” Otherwise, select No and you will be prompted to enter the new meter reading. At the “Setting field device output to 20mA,” Select the OK option and the MFT sets the HART device output to 20.00 mA. The next display asks the user to “Enter meter value” read from the multimeter display. Use the Numeric Grid and soft keys to enter this value. Press Done when finished. Select No if the meter does not read the correct scale value for 20 mA output. Selecting Yes completes the trim operation and the display changes to “Data is being made permanent, please wait…” then to “Returning field device to original output” and finally to “Note- Loop may be returned to automatic control”. Select OK here to complete the Scaled D/A Trim.

This feature also allows custom scaling by entering values for “Scaling Lo value” and “Scaling Hi value”. Selecting the User Defined menu option on the “Select Trim Scale” display provides the Numeric Grid display to allow input of the Scaling Lo and Hi values. Once this is complete, the following display is shown.

Selecting “Change scale” gives the user a chance to further adjust the desired scale.

Burst information is often used within a plant’s information technology framework. The MFT can be used to set a device’s burst mode information and to initiate or terminate the Burst Mode Select function. It does not

To enter the Burst Mode Select option, use the Up or Down soft key to move the selection arrow to Burst Mode Select, then press the Select soft key. Press the Edit soft key, and use the Increase and Decrease soft keys to toggle the burst mode on or off. Press Done when the desired option is displayed. The MFT will query if the new data should be saved. Pressing Yes puts the MFT into the selected burst mode, and returns the MFT to the Hart Output main menu screen. Selecting No leaves the device in the original “As found” burst mode and returns the MFT to the Hart Output main menu screen.

Burst Mode communications are differentiated from normal HART communications with the filled heart symbol displayed when communicating.

Burst Com Number: This register is used to select the information that will be continuously broadcast. The selection will differ from device to device. To enter the Burst Com Number option, use the Up or Down soft key to move the selection arrow to Burst Com Number, then press the Select soft key.

The screen will display the currently selected output setting for the device. Press Back to return to the Hart Output main menu screen if you do not wish to edit the settings.

To edit the current settings, press the Edit soft key. Use the Increase and Decrease soft keys to scroll through the selections for that specific device.

Press Done when the desired selection is displayed. A prompt will appear: Save new data? Press the Yes soft key to accept the new Burst Com Number changes. Pressing No returns the MFT to the Hart Output main menu screen without saving changes to the device.

Save: Allows the MFT to save the HART configuration from a connected device to memory. For Multivariable HART devices: Multi variable HART devices permit the user to select one Primary Variable (PV) from its device variables list and assign the analog output to the selected PV. Sometimes, it is useful to save the parameters of the secondary, tertiary, and other variables in addition to the PV parameters. MFT allows the user to save the configuration by two ways,

1) Only the PV parameters OR

2) The parameters of all variables (primary, secondary, tertiary etc.) by sequentially changing each variable to PV and saving the respective parameter sets. This is done by setting the PV Prompt in Settings menu as Enable.

MFT units are shipped from the factory with the PV Prompt setting defaulted to disable and locked out with the factory lockout code of “321”. To enable all device variable parameters to be saved to the MFT during a Save command, simply unlock the MFT settings (see the procedure in the Settings section earlier in this manual) and reset This makes the MFT, prompt the user-

“Multivariable device, allow PV changes: Yes/No”

If Yes is selected, it will cause the MFT to first save the PV parameters and then change the PV to the secondary variable and save these parameters as well. The MFT continues in this manner until all variable parameters have been saved; then the MFT resets the PV to the original variable.

Send: Allows the MFT to send (download) a HART configuration to an identical HART device. Once a suitable configuration for one unit is created, it can be shared with identical units requiring the same parameters.

DOF Memory Maintenance

DOF flash memory will become fragmented after many DOF download sessions to add new or update existing DOFs. Fragmentation reduces the total number of DOFs that can be saved in memory. 600 DOFs is the nominal capacity of the flash memory). When fragmentation becomes extreme, the MFT will not accept additional DOF downloads. Periodic DOF memory maintenance will be needed to optimize DOF memory.

The Offline screen indicates the number of DOF files stored in memory and the percentage of free memory available for additional files. 320 DOFs ideally use about 58% of the available memory, so 42% of DOF memory should be free. The example at right indicates that only 27% of DOF memory is free. This indicates fragmentation.

To optimize DOF flash memory, it is necessary to delete all DOFs and then reload them all in one session. Connect the MFT to a host PC that has DPC Manager installed (see the DPC Manager Utility section of this manual for more information). Launch DPC Manager and select the “Manage DPC Device Driver and Firmware Updates” option. Go to the Tool Bar and click on “Settings”, then click on the “Advanced” option. The following screen will appear.

320 DOFs will take approximately 90 minutes to load.

MFT 4010 DEVICE SPECIFIC & GENERIC HART® COMMUNICATIONS

Meriam supports a growing number of Device Specific DOFs (Device Object Files). For a current listing of HART devices with full Device Specific MFT communications support, go to http://www.meriam.com/customers/past.asp . Information found there can be sorted by clicking on any column header (manufacturer name, model number, etc.).

To facilitate communications with HART devices that are not yet supported with Device Specific DOF files or that do not require DOF files, the MFT 4010 includes Generic HART Communication capability. This allows the user to communicate with any HART device using Universal and Common Practice commands to poll, configure, and maintain HART devices. Specific functions supported include most polling, tagging, and device configuration and trim operations for analog outputs. Generic communications do not support Device Specific commands for higher order HART functions (see the HART interest for more information on the three command levels).

Using Generic HART Communication The MFT 4010’s Generic HART Communication mode starts automatically when the HART key is pressed or certain Calibrate key functions are selected and no Device Specific DOF (device object file) is found to match the connected

HART device. When this occurs, line two of the display will indicate “Generic” and the device tag number.

In general, both Generic HART and Generic Calibrate modes will operate similarly to their device specific DOF counterparts (see HART Communication and Calibrate sections of this manual for more details). However, the MFT does not display Device Specific related communication menus or options when in the Generic communication mode. For example, the Zero and Sensor trim menu options (normally executed by Device Specific commands) are not displayed for pressure transmitters without DOF support. Please see the Meriam Download Site section of this manual for information on downloading the latest Device Specific DOF files to your MFT.

DOCUMENTING HART CONFIGURATIONS

All MFT 4010 models are able to save and send HART device configuration files. They are also able to upload saved configurations to the Meriam DMS software. The information joins the corresponding tag number history once DMS receives the data.

Within DMS users can review configuration data, compare the most recent configuration to past configurations, and revise configurations for subsequent download to the intended device. See the DMS User’s Manual for more information.

All saved configurations can be deleted from MFT memory using the “Delete All Configs” option in the HART offline mode. Users of the DMS software can use DMS functions to clear the configurations from memory of the MFT 4010. See the DMS User’s Manual for more details.
