2.4 Transmitter overview

The Rosemount™ 2088, 2090F, and 2090P are offered for Gage Pressure (GP) and Absolute
Pressure (AP) measurements. The Rosemount 2088 utilizes piezoresistive sensor
technology for AP and GP measurements.

The major components of the Rosemount 2088, 2090F, and 2090P are the sensor module
and the electronics housing. The sensor module contains the oil filled sensor system
(isolating diaphragm, oil fill system, and sensor) and the sensor electronics. The sensor
electronics are installed within the sensor module and include a temperature sensor, a
memory module, and the analog to digital signal converter (A/D converter). The electrical
signals from the sensor module are transmitted to the output electronics in the electronics
housing. The electronics housing contains the output electronics board, the optional
external configuration buttons, and the terminal block. The basic block diagram of the
transmitter is illustrated in Figure 2-3 on page 7.

When pressure is applied to the isolating diaphragm, the oil deflects the sensor which then
changes its capacitance or voltage signal. This signal is then changed to a digital signal by
the Signal Processing. The microprocessor then takes the signals from the Signal Processing
and calculates the correct output of the transmitter. This signal is then sent to the D/A
converter, which converts the signal back to the analog signal, then superimposes the HART
signal on the 4–20 mA (1–5 Vdc) output.

Reference Manual

00809-0100-4108, Rev CB

An optional LCD display can be ordered that connects directly to the interface board which
maintains direct access to the signal terminals. The display indicates output and
abbreviated diagnostic messages. A glass display cover is provided. For 4-20 mA HART
output, the LCD display features a two-line display. The first line displays the actual
measured value, the second line of six characters displays the engineering units. The LCD
display can also display diagnostic messages.

Note

LCD display utilizes a 5 ⫻ 6 character display and can display output and diagnostic
messages. The LOI display uses an 8 ⫻ 6 character display and can display output,
diagnostic messages, and LOI menu screens. The LOI display comes with two buttons
mounted on the front of the display board. See Figure 2-2.

Reference Manual

00809-0100-4108, Rev CB

The Rosemount 2088, 2090F, and 2090P can be configured either before or after
installation. Configuring the transmitter on the bench using either a Field Communicator,
AMS Device Manager, or LOI ensures all transmitter components are in working order prior
to installation. Verify that the security switch is set in the unlock position ( ) in order to
proceed with configuration. See Figure 4-2 on page 43 for switch location.

Note

LOI is available with the Rosemount 2088 (option M4) but is not available with the
Rosemount 2090F or 2090P.

2.6.1 Configuring on the bench

To configure on the bench, required equipment includes a power supply, and a Field
Communicator, AMS Device Manager, or an LOI (option M4). Wire equipment as shown in

Figure 2-4 below. To ensure successful HART communication, a resistance of at least 250 Ωs

must be present between the transmitter and the power supply, see “Power supply” on

page 46 for details. Connect the Field Communicator leads to the terminals labeled

“COMM” on the terminal block or 1–5 V configuration, wire as shown in Figure 2-4 on

page 9. The Field Communicator is connected to the terminals labeled VOUT/COMM.

Note

 If the transmitter security is on, adjustments to the zero and span will not be able to be

made. Refer to “Configuring transmitter security” on page 43 for security information.

 The span is maintained when the 4 mA/1 V point is set. The span changes when the 20mA

5 V point is set. If the lower range point is set to a value that causes the upper range point
to exceed the sensor limit, the upper range point is automatically set to the sensor limit,
and the span is adjusted accordingly.

 Regardless of the range points, the transmitter measure and report all readings within the

digital limits of the sensor. For example, if the 4 and 20 mA(1–5 Vdc) points are set to
0and10inH
the 25 inH

2.8.3 Damping

The damping command changes the response time of the transmitter; higher values can
smooth variations in output readings caused by rapid input changes. Determine the
appropriate damping setting based on the necessary response time, signal stability, and
other requirements of the loop dynamics within your system. The damping command
utilizes floating point configuration allowing the user to input any damping value within

2.10.1 Configuring alarm and saturation levels

In normal operation, the transmitter will drive the output in response to pressure from the
lower to upper saturation points. If the pressure goes outside the sensor limits, or if the
output would be beyond the saturation points, the output will be limited to the associated
saturation point.

The transmitter automatically and continuously performs self-diagnostic routines. If the
self-diagnostic routines detect a failure, the transmitter drives the output to configured
alarm and value based on the position of the alarm switch. See “Setting transmitter alarm”

on page 45.

2.10.2 Configuring scaled variable

The Scaled Variable configuration allows the user to create a relationship/conversion
between the pressure units and user-defined/custom units. There are two use cases for
Scaled Variable. The first use case is to allow custom units to be displayed on the
transmitter's LCD/LOI Display. The second use case is to allow custom units to drive the
transmitter's 4–20 mA (1–5 Vdc) output.

If the user desires custom units to drive the 4–20 mA (1–5 Vdc) output, Scaled Variable
must be re-mapped as the primary variable. Refer to “Re-mapping device variables” on

page 21.

The Scaled Variable configuration defines the following items:

 Scaled Variable units - Custom units to be displayed.
 Scaled data options - Defines the transfer function for the application
 Pressure value position 1 - Lower known value point with consideration of linear offset.
 Scaled Variable value position 1 - Custom unit equivalent to the lower known value point.
 Pressure value position 2 - Upper known value point
 Scaled Variable value position 2 - Custom unit equivalent to the upper known value point
 Linear offset - The value required to zero out pressures effecting the desired pressure

reading.

2.11 Performing transmitter tests

2.11.1 Verifying alarm level

If the transmitter is repaired or replaced, verify the transmitter alarm level before returning
the transmitter to service. This is useful in testing the reaction of the control system to a
transmitter in an alarm state. Thus ensuring the control system recognizes the alarm when
activated. To verify the transmitter alarm values, perform a loop test and set the transmitter
output to the alarm value (see Tab l e 2 - 5 , 2-6, and 2-7 on page 18).

Note

Before returning transmitter to service, verify security switch is set to the correct position.
Refer to “Verify configuration” on page 11.

2.11.2 Performing an analog loop test

The analog loop test command verifies the output of the transmitter, the integrity of the
loop, and the operations of any recorders or similar devices installed in the loop. It is
recommended that the 4–20 mA (1–5 Vdc) points in addition to alarm levels when
installing, repairing, or replacing a transmitter.

Configuration

November 2017

The host system may provide a current measurement for the 4–20 mA (1–5 Vdc) HART
output. If not, connect a reference meter to the transmitter by either connecting the meter
to the test terminals on the terminal block, or shunting transmitter power through the
meter at some point in the loop. For 1–5 V output, voltage measurement is directly
measured from Vout to (–) terminals.

b. Sensor Temperature
c. Scaled Variable

4. Follow the screen prompts to simulate selected digital value.

2.12 Configuring burst mode

Burst mode is compatible with the analog signal. Because the HART protocol features
simultaneous digital and analog data transmission, the analog value can drive other
equipment in the loop while the control system is receiving the digital information. Burst
mode applies only to the transmission of dynamic data (pressure and temperature in
engineering units, pressure in percent of range, Scaled Variable, and/or analog output), and
does not affect the way other transmitter data is accessed. However, when activated, bust
mode can slow down communication of non-dynamic data to the host by 50 percent.

24

Access to information other than dynamic transmitter data is obtained through the normal
poll/response method of HART communication. A Field Communicator, AMS Device
Manager, or the control system may request any of the information that is normally
available while the transmitter is in burst mode. Between each message sent by the
transmitter, a short pause allows the Field Communicator, AMS Device Manager, or a
control system to initiate a request.

2.13 Establishing multidrop communication

Multidropping transmitters refers to the connection of several transmitters to a single
communications transmission line. Communication between the host and the transmitters
takes place digitally with the analog output of the transmitters deactivated.

Configuration

25

Configuration

November 2017

Multidrop installation requires consideration of the update rate necessary from each
transmitter, the combination of transmitter models, and the length of the transmission line.
Communication with transmitters can be accomplished with HART modems and a host
implementing HART protocol. Each transmitter is identified by a unique address and
responds to the commands defined in the HART protocol. Field Communicators and AMS
Device Manager can test, configure, and format a multidropped transmitter the same way
as a transmitter in a standard point-to-point installation.

Figure 2-18 shows a typical multidrop network. This figure is not intended as an installation

diagram.

operation in the standard point-to-point manner with a 4–20 mA (1–5 Vdc) output signal.
To activate multidrop communication, the transmitter address must be changed to a
number from 1 to 15 for HART Revision 5, or 1–63 for HART Revision 7. This change
deactivates the 4–20 mA (1–5 Vdc) analog output, sending it to 4 mA (1 Vdc). It also
disables the failure mode alarm signal, which is controlled by the upscale/downscale switch
position. Failure signals in multidropped transmitters are communicated through HART
messages.

2.13.1 Changing a transmitter address

To activate multidrop communication, the transmitter poll address must be assigned a
number from 1 to 15 for HART Revision 5, and 1–63 for HART Revision 7. Each transmitter in

Explosions could result in death or serious injury.

Installation of this transmitter in an explosive environment must be in accordance with
the appropriate local, national, and international standards, codes, and practices.
Review the approvals section of the Rosemount 2088, 2090F, 2090P reference manual
for any restrictions associated with a safe installation.

 Before connecting a Field Communicator in an explosive atmosphere, ensure the

instruments in the loop are installed in accordance with intrinsically safe or
non-incendive field wiring practices.

 In an explosion-proof/flameproof installation, do not remove the transmitter covers

when power is applied to the unit.

Process leaks may cause harm or result in death.

 Install and tighten process connectors before applying pressure.

Electrical shock can result in death or serious injury.

Avoid contact with the leads and terminals. High voltage that may be present on leads
can cause electrical shock.

 Avoid contact with the leads and terminals.

Process leaks could result in death or serious injury.

 Install and tighten all four flange bolts before applying pressure.
 Do not attempt to loosen or remove flange bolts while the transmitter is in service.

Replacement equipment or spare parts not approved by Emerson
spare parts could reduce the pressure retaining capabilities of the transmitter
and may render the instrument dangerous.

 Use only bolts supplied or sold by Emerson as spare parts.

Improper assembly of manifolds to traditional flange can damage sensor module.

 For safe assembly of manifold to traditional flange, bolts must break back plane of

flange web (i.e., bolt hole) but must not contact sensor module housing.

3.3.1 Installation considerations

Measurement accuracy depends upon proper installation of the transmitter and impulse
piping. Mount the transmitter close to the process and use a minimum of piping to achieve
best accuracy. Keep in mind the need for easy access, personnel safety, practical field
calibration, and a suitable transmitter environment. Install the transmitter to minimize
vibration, shock, and temperature fluctuation.

Important

Install the enclosed pipe plug (found in the box) in unused housing conduit opening with a
minimum of five threads of engagement to comply with explosion-proof requirements.

3.3.2 Environmental considerations

Best practice is to mount the transmitter in an environment that has minimal ambient
temperature change. The transmitter electronics temperature operating limits are –40 to
185 °F (–40 to 85 °C). Refer to Appendix A: Reference data that lists the sensing element
operating limits. Mount the transmitter so that it is not susceptible to vibration and
mechanical shock and does not have external contact with corrosive materials.

3.3.3 Mechanical considerations

Steam service

For steam service or for applications with process temperatures greater than the limits of
the transmitter, do not blow down impulse piping through the transmitter. Flush lines with
the blocking valves closed and refill lines with water before resuming measurement. Refer
to Figure 3-4 on page 35 through Figure 3-6 on page 36 for correct mounting orientation.

3.4 Installation procedures

Hardware Installation

November 2017

3.4.1 Mount the transmitter

The following are approximate weights of each transmitter:

 Rosemount 2088 2.44 lb (1,11 kg)
 Rosemount 2090F 2.74 lb (1.24 kg)
 Rosemount 2090P 2.96 lb (1.34 kg).

In many cases its compact size and light weight makes it possible to mount directly to the
respective apparatus without using an additional mounting bracket. When this is not
desirable, mount directly to a wall, panel, or two-inch pipe using the optional mounting
bracket (see Figure 3-1 on page 32).

For dimensional drawing information refer to Appendix A: Reference data.

Note

Most transmitters are calibrated in the upright position. Mounting the transmitter in any
other position will shift the zero point to the equivalent amount of liquid head pressure
caused by the varied mounting position. To reset zero point, refer to “Sensor trim overview”

on page 56.

Electronics housing clearance

Mount the transmitter so the terminal side is accessible. Clearance of 0.75-in. (19 mm) is
required for cover removal. Use a conduit plug in the unused conduit opening. Three inches
of clearance is required for cover removal if a meter is installed.

Hardware Installation

Environmental seal for housing

Thread sealing (PTFE) tape or paste on male threads of conduit is required to provide a
water/dust tight conduit seal and meets requirements of NEMA

Consult factory if other Ingress Protection ratings are required.

3.4.2 Impulse piping

Mounting requirements

Impulse piping configurations depend on specific measurement conditions. Refer to Figure

3-4 on page 35 through Figure 3-6 on page 36 for examples of the following mounting con-

figurations:

Liquid measurement

 Place taps to the side of the line to prevent sediment deposits on the transmitter’s

process isolator.

 Mount the transmitter beside or below the taps so gases can vent into the process line.
 Mount drain/vent valve upward to allow gases to vent.

Hardware Installation

November 2017

Gas measurement

 Place tap in the top or side of the line.
 Mount the transmitter beside or above the tap so liquid will drain into the process line.

Steam measurement

 Place tap to the side of the line.
 Mount the transmitter below the taps to ensure that the impulse piping will stay filled

with condensate.

 In steam service above 250 °F (121 °C), fill impulse line with water to prevent steam from

contacting the transmitter directly and to ensure accurate measurement start-up.

Note

For steam or other elevated temperature services, it is important that temperatures at the
process connection do not exceed the transmitter’s process temperature limits.

Best practices

The piping between the process and the transmitter must accurately transfer the pressure
to obtain accurate measurements. There are five possible sources of error: pressure
transfer, leaks, friction loss (particularly if purging is used), trapped gas in a liquid line, liquid
in a gas line, and density variations between the legs.

Hardware Installation

Reference Manual

00809-0100-4108, Rev CB

The best location for the transmitter in relation to the process pipe is dependent on the
process. Use the following guidelines to determine transmitter location and placement of
impulse piping:

 Keep impulse piping as short as possible.
 For liquid service, slope the impulse piping at least 1 in./ft (8 cm/m) upward from the

transmitter toward the process connection.

 For gas service, slope the impulse piping at least 1 in./ft (8 cm/m) downward from the

transmitter toward the process connection.

 Avoid high points in liquid lines and low points in gas lines.
 Use impulse piping large enough to avoid friction effects and blockage.
 Vent all gas from liquid piping legs.
 When purging, make the purge connection close to the process taps and purge through

equal lengths of the same size pipe. Avoid purging through the transmitter.

 Keep corrosive or hot [above 250 °F (121 °C)] process material out of direct contact with

the sensor module and flanges.

 Prevent sediment deposits in the impulse piping.
 Avoid conditions that might allow process fluid to freeze within the process flange.

Hardware Installation

November 2017

3.4.3 Inline process connection

Inline gage transmitter orientation

Interfering or blocking the atmospheric reference port will cause the transmitter to output
erroneous pressure values.

The low side pressure port on the inline gage transmitter is located in the neck of the
transmitter, behind the housing. The vent path is 360 degrees around the transmitter
between the housing and sensor (See Figure 3-7).

Keep the vent path free of any obstruction, such as paint, dust, and lubrication by mounting
the transmitter so that the process can drain away.

3.5 Process connections

3.5.1 Rosemount 2090P

Installing the Rosemount 2090P transmitter involves attaching a weld spud to the tapped
process vessel, attaching the transmitter to the weld spud, and making electrical
connections. If you intend to use an existing weld spud, proceed to the transmitter section
of this installation procedure.

Note

The Rosemount 2090P isolating diaphragm can be mounted flush with the inside diameter
of any vessel larger than three inches in diameter.

Installation of the weld spud should be performed by a skilled welder using a TIG
welder. Improper installation may result in weld spud distortion.

38

Hardware Installation

Reference Manual

00809-0100-4108, Rev CB

3.5.2 Weld spud

1. Using the appropriate size hole saw, cut a hole in the process vessel to accept the weld
spud. The diameter for a weld spud with heat isolator groove is 2.37-in. (60 mm); when
compatible with 1-in. PMC
mm). The hole should produce a tight, uniform fit when coupled with the weld spud.

2. Bevel the edge of the vessel hole to accept filler material.

3. Remove the weld spud from the transmitter and remove the PTFE gasket from the weld
spud.

Excessive heat will distort the weld spud. Weld in sections, as shown in Figure 2-5,
cooling each section with a wet cloth. Allow adequate cooling between passes.
To reduce the chances of distorting the weld spud (for 1.5-in. connection), use a he
sink—Rosemount Part Number 02088-0196-0005.

4. Position the weld spud in the vessel hole, place heat sink and tack spud in place using the
welding sequence shown in Figure 2-8. Cool each section with a wet cloth before
proceeding to the next section.

Hardware Installation

November 2017

®

process connection style spud, diameter is 1.32 in. (33,4

5. Weld the spud in place using 0.030 to 0.045-in. (0,762 to 1,143 mm) stainless steel rod
as filler in the bevelled area. Using between 100 and 125 amps., adjust the amperage for

0.080-in. (2,032 mm) penetration.

3.5.3 Transmitter

1. After the weld spud has cooled, remove the heat sink and install the PTFE gasket into the
weld spud. Ensure that the gasket is properly positioned within the weld spud; improper
placement could cause a process leak.

2. Position the transmitter into the spud and begin to engage the threads. Rotate the
transmitter prior to seating the threads completely to enable access to the housing
compartments, the conduit entry, and the LCD display.

3. Hand tighten the transmitter using the knurled retaining ring, then snug an additional
turn with adjustable pliers.

Important

Do not over-tighten the retaining ring. A spanner wrench hole is located on the knurled
portion of the retaining ring to assist in transmitter removal if it is over-tightened.

Transmitter case grounding

Always ground the transmitter case in accordance with national and local electrical codes.
The most effective transmitter case grounding method is a direct connection to earth
ground with minimal impedance. Methods for grounding the transmitter case include:

 Internal ground connection: the internal ground connection screw is inside the FIELD

TERMINALS side of the electronics housing. This screw is identified by a ground symbol
( ). The ground connection screw is standard on all Rosemount 2088, 2090F, 2090P

Transient protection terminal block grounding

The transmitter can withstand electrical transients of the energy level usually encountered
in static discharges or induced switching transients. However, high-energy transients, such
as those induced in wiring from nearby lightning strikes, can damage the transmitter.

The transient protection terminal block can be ordered as an installed option (Option Code
T1) or as a spare part to retrofit existing Rosemount 2088, 2090F, and 2090P transmitters in
the field. See “Ordering Information, Specifications, and Drawings” on page 31 for part
numbers. The lightning bolt symbol shown in Figure 4-10 on page 51 identifies the
transient protection terminal block.

equipment.

c. Set/check basic configuration parameters.

5.4 Calibration overview

The Pressure Transmitter is an accurate instrument that is fully calibrated in the factory.
Field calibration is provided to the user to meet plant requirements or industry standards.
Complete calibration of the transmitter can be split into two halves: Sensor Calibration and
Analog Output Calibration.

Sensor calibration allows the user to adjust the pressure (digital value) reported by the
transmitter to be equal to a pressure standard. The sensor calibration can adjust the
pressure offset to correct for mounting conditions or line pressure effects. This correction is
recommended. The calibration of the pressure range (pressure span or gain correction)
requires accurate pressure standards (sources) to provide a full calibration.

54

Like the Sensor calibration, the analog output can be calibrated to match the user
measurement system. The Analog Output Trim (4–20 mA/ 1–5 V output trim) will calibrate
the loop at the 4 mA (1 V) and 20 mA (5 V) points.

The Sensor calibration and the analog output calibration combine to match the
transmitter’s measurement system to the plant standard.

 4–20 mA/ 1–5V Output trim using other scale (page 61)

5.4.1 Determining necessary sensor trims

Bench calibrations allow for calibrating the instrument for its desired range of operation.
Straight forward connections to pressure source allow for a full calibration at the planned
operating points. Exercising the Transmitter over the desired pressure range allows for
verification of the analog output. “Trim the pressure signal” on page 56 discusses how the
trim operations change the calibration. It is possible to degrade the performance of the
transmitter if a trim is done improperly or with inaccurate equipment. The transmitter can
be set back to factory settings using the “Recall factory trim—sensor trim” on page 59.

Determine the necessary trims with the following steps.

November 2017

1. Apply pressure.

2. Check digital pressure, if the digital pressure does not match the applied pressure,
perform a digital trim. See “Perform a sensor trim” on page 57.

3. Check reported analog output against the live analog output. If they do not match,
perform an analog output trim. See “Performing digital-to-analog trim (4–20mA/ 1–5 V

output trim)” on page 60.

Trimming with configuration buttons

Local configuration buttons are external buttons located underneath the top tag of the
transmitter. There are two possible sets of local configuration buttons that can be ordered
with the Rosemount 2088 and used to perform trim operations: Digital zero trim and LOI.
To access the buttons, loosen screw and rotate top tag until buttons are visible.

 LOI (M4): Can perform both digital Sensor Trim and the 4–20mA Output Trim (analog

output trim). Follow the same procedures listed in trimming with Field Communicator or
AMS Device Manager listed below.

 Digital zero trim (DZ): Used for performing a sensor zero trim. See “Determining

calibration frequency” on page 56 for trim instructions.

All configuration changes should be monitored by a display or by measuring the loop
output.

5.4.2 Determining calibration frequency

Calibration frequency can vary greatly depending on the application, performance
requirements, and process conditions. Use the following procedure to determine
calibration frequency that meets the needs of your application.

1. Determine the performance required for your application.

2. Determine the operating conditions.

3. Calculate the Total Probable Error (TPE).

4. Calculate the stability per month.

5. Calculate the calibration frequency.

Sample calculation for Rosemount 2088

Step 1: Determine the performance required for your application.

Required Performance: 0.50% of span

Step 2: Determine the operating conditions.

Reference Manual

00809-0100-4108, Rev CB

Transmitter: Rosemount 2088G, Range 1 [URL = 30 psi (2,1 bar)]

Calibrated Span: 30 psi (2,1 bar)

Ambient Temperature Change: ± 50 °F (28 °C)

Step 3: Calculate total probable error (TPE).

TPE = = 0.309% of span

Where:

Reference Accuracy = ± 0.075% of span

Ambient Temperature Effect = ± (0.15% URL + 0.15% of span) per 50 °F = ± 0.3% of span

Static Pressure Effect = 0% (does not apply to in-line products)

Step 4: Calculate the stability per month.

Step 5: Calculate calibration frequency.

5.5 Trim the pressure signal

5.5.1 Sensor trim overview

56

A sensor trim corrects the pressure offset and pressure range to match a pressure standard.
The upper sensor trim corrects the pressure range and the lower Sensor trim (zero trim)
corrects the pressure offset. An accurate pressure standard is required for full calibration. A
zero trim can be performed if the process is vented.

Reference Manual

00809-0100-4108, Rev CB

Zero trim is a single-point offset adjustment. It is useful for compensating for mounting
position effects and is most effective when performed with the transmitter installed in its
final mounting position. Since this correction maintains the slope of the characterization
curve, it should not be used in place of a Sensor Trim over the full sensor range.

Note

Do not perform a zero trim on Rosemount 2088A, 2090FA, 2090PA Absolute Pressure
Transmitters. Zero trim is zero based, and absolute pressure transmitters reference absolute
zero. To correct mounting position effects on an Absolute Pressure Transmitter, perform a
low trim within the sensor trim function. The low trim function provides an offset correction
similar to the zero trim function, but it does not require zero-based input.

Upper and lower sensor trim is a two-point sensor calibration where two end-point
pressures are applied, all output is linearized between them, and requires an accurate
pressure source. Always adjust the low trim value first to establish the correct offset.
Adjustment of the high trim value provides a slope correction to the characterization curve
based on the low trim value. The trim values help optimize performance over a specific
measurement range.

5.5.2 Perform a sensor trim

When performing a sensor trim, both the upper and lower limits can be trimmed. If both
upper and lower trims are to be performed, the lower trim must be done prior to the upper
time.

Note

Use a pressure input source that is at least four times more accurate than the transmitter,
and allow the input pressure to stabilize for 10 seconds before entering any values.

Performing a digital zero trim (option DZ)

A digital zero trim (option DZ) provides the same function as a zero/lower sensor trim, but
can be completed in hazardous areas at any given time by simply pushing the zero trim
button when the transmitter is at zero pressure. If the transmitter is not close enough to
zero when the button is pushed, the command may fail due to excess correction. If ordered,
a digital zero trim can be performed by utilizing external configuration buttons located
underneath the top tag of the transmitter, see Figure 5-1 on page 55 for DZ button
location.

1. Loosen the top tag of the transmitter to expose buttons.

2. Press and hold the digital zero button for at least two seconds, then release to perform a
digital zero trim.
