mA/V dc Operation

mA/V dc Operation
The EMM provides measurement of V dc and mA with or without 24 V loop power.
To enable the mA/VDC function:
1. From the Controller Main screen, push EMM/HART on the left of the touchscreen.
2. Push mA/VDC to go into electrical measurement mode.
3. Choose the measurement mode as required. Push mA/DCV to toggle the mode between mA or V dc. In mA
measurement mode, push 24V Loop to enable/disable 24V loop power for a mA transmitter. DCV mode disables
24V loop power.
V dc Measurement
In V dc measurement mode, the Product measures the input dc voltage from 0 V to 30 V.
mA Measurement
In the mA measurement mode, the Product measures dc current from 4 mA to 20 mA.
See the Pressure Controller's Operators Manual for how to use the Programs Task with mA or V dc transmitters.
Pressure Transmitter Instructions
The Product tests, troubleshoots, and calibrates analog DUTs and smart pressure transmitters with HART
functionality. Pressure transmitters are usually classified as analog transmitters or smart transmitters.
Analog Transmitters
Analog transmitters let the user make two adjustments:
1. Zero the transmitter by adjusting the LRV (Lower Range Value) of the transmitter to the zero-pressure point that
supplies an output of 4 mA.
2. Adjust the URV (Upper Range Value) of the transmitter to the upper-working pressure that supplies an output of
20 mA.
These transmitters are usually adjusted with a screwdriver by turning two potentiometers on the top or the side of
the transmitter. The Product helps to calibrate these analog transmitters by providing an accurate, easy to control
source of pressure while also precisely measuring the analog 4-20 mA signal.

HART Operation
Highway Addressable Remote Transducer (HART) is an industry standard that defines the communications protocol
between smart field devices and a control system that uses traditional 4-20 mA wiring. HART allows the technician
to configure and adjust variables stored and used by the transmitter. The HART function of the Product allows for
calibration and testing of many HART-enabled devices such as transmitters. The Product uses Universal Practice
Commands and many Common Practice Commands that allow the user to change parameters and easily make
adjustments to the HART device.
Some HART devices require specific device drivers to make changes to parameters for which the EMM is not
equipped. In this case, use of a field communicator such as the Fluke 754 Documenting Process Calibrator is
necessary.
Smart Transmitters
Smart transmitters are more complex than analog transmitters and offer more features that allow the transmitters to
store and transmit more information to a central control center. For example, many smart transmitters have a digital
signal that transmits not only the analog 4-20 mA signal, but also the pressure reading back to the central control
center. While many newer systems use this digital signal, most use the analog 4-20 mA signal that requires the
analog circuit to be adjusted when calibrated.
To communicate with smart transmitters, HART communication protocol is used. Many of the HART variables are
used to calibrate the smart transmitter. The EMM is HART-enabled and uses Universal Practice Commands and
many HART Common Practice Commands to change parameters and make adjustments to the HART device. Many
smart transmitters use specific commands that are not part of the common practice or universal command library.
These commands are sometimes needed to perform a digital sensor trim (for example) and are referred to as device
drivers. The EMM does not contain any device drivers.
Connect to a HART Transmitter
To connect the Product to a HART transmitter:
1. Connect the test leads from the Product to the appropriate terminals on the HART device. Observe polarity. See
Figure 2.
2. Push MAIN>EMM/HART. The HART connection menu shows these settings:
• 250 Ohm Resistor – When ON, the Product uses the built-in 250 Ω resistor required for HART
communication.
• Use HART Unit – When YES, the pressure unit of the controller changes to match the unit of the pressure
transmitter.
• Write Lock – When ON, the transmitter is protected from data changes.
3. Push Connect. The controller scans (polls) for connected devices from addresses 0 to 65. When a transmitter is
found, data is obtained. If the controller does not detect a device, check the connections and wire polarity and
then push Connect again. If a connection cannot be made after multiple attempts, troubleshoot the transmitter
with the mA mode. See Using the mA Function to Test and Troubleshoot.

Trim PV Zero
The Trim PV Zero command zeros the pressure sensor in a transmitter. The resulting offset must be within limits by
each device. The span of Primary Variable remains constant. This command does not affect or interact with the
Upper or Lower-Range values.
1. Select HART Tasks on the HART menu.
2. Select Trim PV Zero.
3. Push Zero PV to zero PV.
Trim Current Output
The Trim Current Output commands adjust the transmitter digital to analog converter (DAC) at the 4 mA and 20 mA
points.
To Trim Current Output:
1. Select HART Tasks on the Hart menu.
2. Select Trim Current Output from the menu.
3. Use Averaging Measurement and Averaging Time to average the measurement value applied to the trim.
4. Push Start to start Trim.
5. Push Trim 4mA to start trimming the 4 mA point. The Send button is enabled when measuring value is stable.
6. Push Send to send the 4 mA trimming value to DUT.
7. After 4 mA trimming is complete, push Trim 4mA to repeat the 4 mA trimming, if necessary. Or push Continue
to move trim to 20 mA.
8. Push Trim 20mA to start trimming the 20 mA point. The Send button is enabled when measuring value is
stable.
9. Push Send to send 20 mA trimming value to DUT.
10. After 20 mA trimming is complete, push Trim 20 mA to repeat the 20 mA trimming if necessary. Or push Exit to
exit.
Trim by Re-ranging
You can adjust the transmitter by re-ranging the upper and lower range values. This type of trim is typical for analog
and smart transmitters used in analog processes. This trim function alters the transmitter’s interpretation of the input
signal.
To trim by re-ranging:
1. Push HART Tasks on the HART menu.
2. Select Trim by Re-ranging.
In the Trim by Re-ranging menu:
• Range: 4 mA/20 mA/Both – Use to select a point or both to trim
o 4mA - Only trim 4 mA
o 20mA - Only trim 20 mA
o Both - Trim both 4 mA and 20 mA
• LRV - Configure the lower range value of transmitter

Note
Changing the LRV affects the URV. If the LRV should be tested against ATM, check the Set to
ATM checkbox. When is Set to ATM is pushed, the LRV is non-editable.
• URV - Configure the upper range value of transmitter.
• Closed Loop:
o ON - Automatically sets the pressures to the LRV and URV values and dwells for the time specified in
the Dwell Time field. The measurements are taken from the amount of time shown in the Averaging
Time field.
o OFF - Trim the function manually.
• Dwell Time:
This is a user-configurable amount of time for how long the pressure dwells before measurements are
taken.
Note
Once at the setpoint and the pressure stabilizes (Ready is shown), the dwell countdown timer
starts. Once the dwell is finished, if closed loop was used, then the measurement is taken and
the controller continues to the next setpoint. If closed loop is OFF, push continue to go to the
next setpoint.
3. In the Trim by Re-ranging main menu, push Start to start trim.
4. If the Closed Loop was ON, the trim process automatically progresses without user interaction. Otherwise,
the Closed Loop is OFF.
5. Push Trim to trim and change to next range.
6. If necessary, push Lower Range or Upper Range, as necessary.
7. When the trim process is finished, follow the display guide Trim Complete, push Exit to exit.
Note
This trim process changes the upper and lower range values to compensate the sensor’s
error.
Write LRV/URV
To change the working range of a HART Transmitter by changing the LRV or URV:
1. Select Write LRV and URV.
2. In the change menu, input the new LRV and URV values.
Note
LRV cannot be set to lower than Lower Transmitter Limit (LTL) and the URV cannot be set
greater than the Upper Transmitter Limit (UTL).
3. Push Send to save the new values.
4. Push Exit to exit.
