1.6 TRANSMITTER PRINCIPLES OF OPERATION
The mechanical system consists of a gaged diaphragm. One side of the diaphragm is in direct contact
with the fluid media (gas or liquid) while a strain gage element in the configuration of a Wheatstone
bridge is bonded to the backside.
The deflection of the diaphragm causes a change in the resistance of the strain gage and hence a change
in the balance of the bridge. The amount of imbalance is directly proportional to the applied pressure.
This completes the translation of pressure applied to the diaphragm into a usable electrical signal.
The low level output signal from the bridge is amplified via an instrumentation amp circuit. The
amplified signal then goes to the input of the analog-to-digital (A/D) converter.
Once the microprocessor has the converted voltage input from the A/D converter, the digital signal is
sent to a digital-to-analog (D/A) converter which modulates the current of the unit’s power supply
between 4 and 20 mA for an output current proportional to the applied pressure.

2 NOTES ON SAFETY
he operator or owner of the larger overall system is responsible for following the safety and accident
T
prevention regulations that apply to the specific application.
DYNISCO will not be held liable for any injury, loss or damage resulting from failure to follow the
instructions in this manual.
Warnings
The SPX is an ESD sensitive component. Electrostatic discharge may damage the SPX. Take ESD
precautions.
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.
Mounting and electrical connection of the PT must be done by specialists with EMC training, following
all applicable regulations, and in pressure-less, voltage-free, intrinsically safe condition with the
machine switched off. The machine must be secured against being switched back on!
EMC/CE Compliant Connection
Earth the machine section with the process connections for the SPX in accordance with regulations. The
SPX must be connected to earth via the process connection.
Connect the shield of the connecting cable on both sides, making sure it conducts with full and
continuous contact.
When introducing the connecting cable into an EMC compliant switch cabinet, for example, connect the
shield correctly (cable gland, conducting, full contact, and continuous) to the conductive housing or
route it via a built-in cable connector that is also connected to the conductive housing. Connect unused
cable cores or free cable ends correctly to the cable shield on both sides.

-12-
Temperature
The SPX can be used in me
dia temperatures up to +85°C (based on configuration). If the pressure
transmitter is used in other applications, the safety and accident prevention regulations specific to that
application must be followed. Ambient temperature for the electronics housing is +85°C maximum in
areas that are not classified as hazardous.
Higher temperatures can result in damage and malfunction. Do not install the pressure transmitter in
places where these temperatures are exceeded.
Use in Hazardous Classified Areas
Se
veral configurations of the SPX are designed and approved for use in hazardous classified areas. Units
intended for installation in these areas must bear the applicable approval agency label.
The SPX is specially designed for measuring pressure in explosive gas atmospheres for Zone 0 under
safety class II 1 G Ex ia IIC T6/T4 (T6, Ta = -20 to + 50°C; T4, Ta = -20 to + 85°C). The SPX is also approved
for hazardous gas area Zone 1 under safety class II 2 G Ex ia IIC T6/T4 (T6, Ta = -20 to + 60°C; T4, Ta = -20
to + 85°C).
The maximum T
(medium temperature) for temperature class T6 is +60°C and for T4 is +85°C. The
med
medium temperature for the SPX is defined as the temperature of the pressure transmission fluid below
the measuring diaphragm (See Figure 1-1). This temperature can be verified by measuring the surface
temperature at the base of the electronics housing.
For category 1 (Zone 0) installations, care must be taken to avoid the danger of ignition due to
electrostatic discharges (ESD). The chance for static build up on the cable surface during normal
conditions of use, maintenance and cleaning must be eliminated. Install the cable in an appropriate
conduit or use some other cable reliable installation technique to avoid static electricity at the cable
surface.
The free length of the cable must be below 5 cm. If metallic conduits are used they need to be
g
rounded. If nonmetallic conduits are used they need to be antistatic (< 1G Ohm/cm
2
).
The housing shall be connected reliably to the local equipotential bonding system.
Those variants that include the material aluminum shall be installed in such a way that sparking as a
sult of impact or friction between aluminum and steel is excluded. Impact or friction between
re
aluminum and stainless steel is allowed if the existence of rust particles can be excluded.
For application as Category-1-E
conductive coating (R
surface < 10
quipment the connecting cable shall be equipped with a suitable
9
Ω) to avoid possible electrostatic charge.
After installation before operating the device the user must check that the complete
installation and wiring is intrinsically safe. Care must be taken that the power source is a
certified apparatus.

Deviation of the supply voltage from the value given in the technical specifications, or reverse polarity,
can damage the pressure transmitter and cause malfunctions that can pose a risk of explosion. Operate
only with an intrinsically safe, EMC compliant power supply with the following specifications when
employing the pressure 4-20 mA output:
Supply Voltage max. Uo = 30 V
DC Current Output max. Io = 100 mA
Power max. Po = 0.750 W
The specified values of Lo and Co for the power supply need to be greater than Ci + Ccable and Li +
Lcable.
Internal Inductance Li < 40 µH
Internal Capacitance Ci < 4.5 nF
If the transmitter is installed in hazardous areas, only passive devices like switches or resistors may be
connected between the RCAL+ and RCAL- signals. Connection of any active electronic circuits or voltage
or current sources is not allowed.
Certain configurations of the SPX are also designed for use in hazardous areas as Explosion-proof and
Dust Ignition-proof by Factory Mutual for Class I, Division 1, Groups A, B, C & D, and Class II, III, Division
1, Groups E, F & G.
For SPX units that are explosion-proof approved for Class I, Division 1, Groups A, B, C & D the power
supply rating is 13-30 Vdc.
Additional Comments:
1) Do not remove the transmitter push-button seal screws in explosive environments when the circuit
is live.
2) Transmitter push-button seal screws must be fully engaged to meet Explosion-proof requirements.
3) Before connecting a HART handheld communicator in an explosive atmosphere, make sure the
instruments in the loop are installed in accordance with intrinsically safe or non-incendive field wiring
practices.

2.1 SAFETY integrity and performance level applications
User’s obligations
The operator or owner of the larger overall system, e.g. a machine, is responsible for following the
safety and accident prevention regulations that apply to the specific application.
Intended Use
See Certificate in section 9.4
Safety Function
See Certificate in section 9.4
For units with the optional monitoring channel (Guardian Series, Option Code = GCxxx):
Under normal operating conditions the relay contacts are closed. In the event that a failure is detected
the relay contacts open. Detectable failures include:
1) Loss of Power
2) Open Gage
3) Input over a predefined (customer selectable at time of order) threshold
The Guardian Series transducer has been designed to provide a protective measure. This has been done
by the avoidance and control of systematic and random failures.
This product will:
Measure the pressure and provide a safety relay output. Since this is being used to perform a protective
measure, this sensor should only be used for monitoring the pressure and not controlling the process.
Best practices declare that safety and control must be independent from each other.
The Guardian Series transducer detects many hardware failures including an open or short in the
measuring gage and if there is an overpressure condition. If any of these failures occur, the output relay
will open. It is the user’s responsibility to connect this relay to the system in such a way that when this
relay opens, it brings the system to a safe state.

This fault state is not latched. It is up to the user to latch this error if desired.
Recommended practices
This Guardian Series transducer must be installed in such a way that the opening of the
output relay will bring the system to a safe state. In this safe state the instrument that is
monitoring the pressure should be left operational.
This error indication is not latched. If it is necessary to latch the error until it is manually
reset, this is the user’s responsibility.
At startup and on a periodic basis the safety system should be tested to ensure proper
operation. This will require applying a pressure to the Guardian Series transducer that is
over the safe level but less than the maximum pressure. Verify that the protective measure
is initiated to take the machine to a safe operating condition.
Use of qualified personnel
The product may only be assembled, installed, configured, commissioned, operated and
maintained by persons with proven skills. Persons with proven skills are suitably
experienced to operate devices, systems, plant and machinery in accordance with the
general standards and guidelines for safety technology.
It is the user’s responsibility only to employ personnel who:
• Are familiar with the basic regulations concerning health and safety and accident prevention
• Have read and understood the safety guidelines given in this description
• Have a good knowledge of the generic and specialist s ta nd a rds applicable to the specific application

process connections that satisfy the requirements below. A process connection that does not satisfy
these requirements can damage the transmitter.
Insure the process connection is clear of any debris and is machined to the proper dimensions. In
applications involving high temperature operation and/or repeated thermal cycling a good high quality
anti-seize compound should be applied to the threaded surfaces.
Install unit into the process connection (Do NOT torque transmitter into the hole at this time!). Allow
time for the transmitter snout temperature to equalize to the process temperature. This will help
eliminate thread galling and ease removal later. There should be NO pressure applied at this time.
Always use a torque wrench applied to the designated wrench flats while screwing the transmitter in
and out. Do not apply the tool to the housing or housing/sensor connection.
After temperatures have equalized tighten transmitter into process connection.
When removing the SPX, carefully clean the diaphragm of the transmitter with a soft cloth while the
medium is still malleable.
Always remove the SPX prior to cleaning the machine with abrasives or steel wire brushes. Also, do not
clean the SPX with hard objects, such as a screwdriver, a wire brush, etc. This will possibly damage the
transmitter.
Burn Hazard! The SPX can be very hot when removed. WEAR PROTECTIVE GLOVES!
Careful attention should be paid to correctly machine the mounting port. Failure to use
the recommended mounting port may result in erroneous pressure measurement, difficult transducer
removal, premature sensor failure, process fluid leaks, and personnel hazard.
5.2 ELECTRICAL CONNECTION
Connect power to the transmitter. For conduit output configuration, Red wire is Sig+/Exc +, Black wire is
Sig-/Exc-, Green wire is Ground. For a 6 pin connector version, Pin A is Sig+/Exc+ and pin B is Sig-/Exc-.
Insure proper loop supply voltage is applied to transmitter.

6 COMMISSIONING
ere are two ways of commissioning the SPX transmitters. This can be done by utilizing the ZERO and
Th
SPAN actuators or by HART Communications via a communicator connected to the pressure loop.
If the SPX is equipped with the optional HART Communications, it is not necessary to access the
zero/span actuators on the sensor.
If the transmitter is not equipped with HART then the zero/span actuators must be utilized. However,
Sections 6.3 through 6.8 and 6.11 may be skipped.
6.1 WHY A TRANSMITTER MUST BE REZEROED
The transmitter output must be nulled at zero pressure after installation when the machine has
stabilized at operating temperature. This is easy to understand why when considering the mechanical
properties of the sensor.
Depending on the orientation of the sensor, the weight of the diaphragm will have an effect on the
sensing diaphragm. The weight of the diaphragm will either increase or decrease deflection of the
diaphragm, creating a shift in the strain gage output that can appear as a positive or negative pressure.
There are some other effects that may affect the zero as well, such as torque, side loading, etc. For
more information contact Dynisco.

ATTENTION
ATTENTION
providing a window into the process
All of these effects can be compensated for by setting the transmitter zero after the machine has
stabilized at operating temperature.
6.2 UTILIZING THE ZERO AND SPAN ACTUATORS
When the transmitter output needs to be corrected due to mounting location and temperature shift the
zero actuator can be used (if a HART Communicator is not available.) Please wait until the process has
been brought to operating temperature before zeroing. The zero procedure is only recommended after
the process temperature has stabilized and the SPX electronics housing has been permanently installed.
When the actuator is depressed in a certain sequence, the output will be corrected to reflect 4 mA. This
is done by the transmitter electronics automatically by adjusting the LRV and URV settings
simultaneously to the offset required to obtain 4 mA. Normally a Zero calibration is all that is required
after installation since the Transmitter span has been calibrated at the factory. In the event the Full
Scale output is not correct when checked against a calibrated pressure source or dead weight tester, the
transmitter span can be adjusted via the Span actuator. This is performed by applying a known
calibrated full scale pressure to the transmitter and depressing the Span actuator in a certain sequence.
When complete, the transmitter electronics will have adjusted the URV to correct to output to equal 20
mA.
The span actuator should never be used to set the URV without zeroing the PT with the zero actuator
first.
If for some reason the calibration is incorrect and the user wishes to revert back to the Factory
Calibration, a procedure can be performed to revert the calibration back to factory state. Refer to
“Resetting to Factory Default Settings” in this Chapter.
6.2.1 ZERO AND SPAN PROCEDURE
1. Connect Power Supply to SPX signal leads with 250 Ohm load and milliamp meter in series with
loop.
2. If commissioning on the bench with a dead weight tester or calibrated pressure source, ensure
pressure connection is free of leaks.
3. Apply power to the SPX transmitter and observe loop current with zero pressure applied. It
should be 4 mA. If other than 4 mA proceed to step 4.
4. Perform Zero Function.
i. Do not remove seal screw when the circuit is live in a hazardous area.
ii. Remove zero pushbutton seal screw.
iii. Using a 2mm or smaller Allen key, depress the pushbutton for a ½ second.
iv. Release pushbutton for a ½ second.
v. Depress the pushbutton again for a ½ second and release.

Steps past this point are not part of a normal bench setup and should only be performed by qualified
individuals, as the SPX is highly stable and has been factory calibrated with highly accurate pressure
generators. This function should only be performed on such equipment.
5. Apply Full Scale pressure and verify output is 20 mA. If output is other than 20 mA, perform
Local Span adjustment:
i. Do not remove seal screw when the circuit is live in a hazardous area.
ii. Remove span pushbutton seal screw.
iii. Using a 2mm or smaller Allen key, depress the pushbutton for a ½ second.
iv. Release pushbutton for a ½ second.
v. Depress the pushbutton again for a ½ second and release.
The available pressure is now adopted as the new upper range value.
6.3 UTILIZING THE HART COMMUNICATIONS
The zero procedure is only recommended after the process temperature has stabilized and the SPX
electronics housing has been permanently installed. When the zero trim function is selected (HART
Quick key 1,2,5,1,3,1) the output will be corrected to reflect zero pressure. This is done by the
transmitter electronics automatically by adjusting digital PV to zero and analog output will be 4 mA.
Normally a Zero Trim is all that is required after installation since the Transmitter span has been
calibrated at the factory
In the event the Full Scale output is not correct when checked against a calibrated pressure source or
dead weight tester, the Transmitter span can be adjusted by performing the Sensor Trim function. This is
performed by first applying Zero Pressure and selecting Lower Sensor Trim (HART Quick Key 1, 2, 5, 1, 3,
2) and following the prompts on the HART Communicator. When complete, apply a known calibrated
full scale pressure to the Transmitter and selecting Upper Sensor Trim (HART Quick Key 1, 2, 5, 1, 3, 3)
and follow the prompts on the HART Communicator. When complete, the transmitter electronics will
have adjusted the digital PV to correct to full scale output.
Never perform upper sensor trim without performing lower sensor trim first.

6.3.2 CONNECTING THE HART HANDHELD COMMUNICATOR
In hazardous areas, refer to the handheld communicator instruction manual for instructions for HART
Communicator to function properly.
A minimum of 250 Ohms resistance must be present in the loop.
The HART Communicator does not measure loop current directly.
The HART Communicator can interface with the SPX anywhere along the 4 - 20 mA cable as shown in the
following figure.

3. Apply power to the SPX transmitter and turn on the HART Communicator by pressing the
ON/OFF key. The LCD display should show [SPX-T or SPX depending on model] in the upper left
corner. If this is not present, consult the Troubleshooting section of this manual.
4. Set PV Units (Fast Key 1,3,2) to appropriate pressure unit. (e.g. psi, Bar, kgf/cm2, MPa)
5. Set Tag (Fast Key 1,3,1).
6. If transmitter output needs to be re-ranged, set the appropriate LRV (Fast Key 4,1) and URV
(Fast Key 4,2)
• Note: URV cannot be turned down below the PV Minimum span (Fast Key 1,4,1,5)
7. Set Lower Trim (Fast Key 1,2,5,1,3,1)
8. Verify SPX transmitter output. Zero pressure output should read 4 mA.
Steps past this point are not part of a normal bench setup and should only be performed by qualified
individuals, as the SPX is highly stable and has been factory calibrated with highly accurate pressure
generators. This function should only be performed on such equipment.
9. Next, using calibrated pressure source, apply pressure equal to value set in URV in step 6.
Output should equal 20 mA. If output does not equal 20 mA proceed to step 10.
10. To calibrate full scale output, first apply pressure equal to full scale pressure of unit. Next
perform Upper Sensor Trim (Fast Key 1,2,5,1,3,2). Output should now equal full scale pressure.
11. If Transmitter Output Damping is required, set PV Damping (Fast Key 1,3,5) to the appropriate
value.
12. Press the left arrow key until the HART Communicator is off-line then turn the power off.
The SPX pressure transmitter is now ready to be installed in the process.
6.4 SPX ANALOG OUTPUT
The SPX has a 4-20 mA output proportional to pressure for normal operating conditions. However,
unlike a traditional sensor, the SPX performs self-diagnostic routines continually during operation. If a
special condition is detected, the transmitter drives its analog output outside the normal saturation
values to indicate that investigation is necessary (this condition is called fail-safe mode alarm). The
conditions detected by the self-diagnostic routines (and the corresponding effect on the analog output)
are listed later in this section.
When a special condition is detected, the SPX goes into fail-safe mode and the transmitter output goes
high, by default. However, using a HART communicator, the transmitter can also be configured to drive
its output low or to freeze the output where it was just before the fail-safe was detected. The actual
analog output levels are indicated below.
A low alarm (3.6 mA) is possible but not recommended because HART communications are not
guaranteed until the cause of the alarm is removed.
Using the HART communicator, the specific condition that triggered the fail-safe mode alarm can be
read for diagnostic purposes (see Status in the HART menu tree).

n a fail-safe condition the PV is not affected and can still be read using the handheld HART
I
communicator. For process related fail-safe conditions, the transmitter will remain in the alarm state
until the source of error disappears. If certain electronics errors are detected, the fail-safe condition will
latch until a reset is performed by either cycling the power or through a software command.

6.7 SPX TRANSMITTER FUNCTIONS VIA HART
Zero Trim (1,2,5,1,3,1)
Digital Correction to zero which affects the digital output. This differs from Lower
Sensor Trim in that zero trim is ONLY performed at zero pressure.
Lower Sensor Trim (1,2,5,1,3,2)
Digital Correction to zero which affects the digital output. This differs from Zero Trim in that Lower
Sensor Trim can be performed at pressures above zero.
Note: This must be performed before Upper Sensor Trim. Only perform this function with a known
calibrated pressure source.
Upper Sensor Trim (1,2,5,1,3,3)
Digital correction to Full Scale which affect digital output.
Note: Lower Sensor Trim must be performed before Upper Sensor Trim. Only perform this function with
a known calibrated pressure source.
Digital to Analog trim (1,2,5,1,2)
This is used to match the digital representation of the analog output with its actual analog loop current.
Note: This should only be performed with a known Calibrated Current (mA) meter.
Reranging
The SPX allows for the 4 mA and 20 mA points (LRV and URV respectively) to be adjusted so that output
resolution can be improved. A Re-range or “Turndown” ratio of 6:1 is possible. Accuracy specifications
remain dependent upon the Full Sensor Range without any turndown applied. Three methods of Reranging the SPX Transmitter are outlined below.
Note: If pressure applied to the transmitter is not in the range of the 6:1 turndown ratio, the transmitter
will reject the Span attempt. This will be indicated by the output not adjusting to 20 mA after a few
attempts using the Span Actuator.
Reranging via Zero/Span Actuators
When HART Communication is not used, LRV and URV values are entered by applying zero pressure to
the SPX-T and “Rezeroing” by:
i. Do not remove seal screw when the circuit is live in a hazardous area.
ii. Remove zero pushbutton seal screw.
iii. Using a 2mm or smaller Allen key, depress the pushbutton for a ½ second.
iv. Release pushbutton for a ½ second.
v. Depress the pushbutton again for a ½ second and release.
The LRV and URV have now been adjusted to zero the device without affecting the span.
After Rezeroing, it is possible to set the span by adjusting the URV with the span actuator. The span
actuator should never be used to adjust the URV without using the zero actuator to set the LRV first.

ATTENTION
providing a window into the process
URV or Full Scale Turndown is performed by applying any pressure, within the 6:1 ratio of the
transmitter that you want to be the 20 mA point. When the pressure is held steady:
i. Do not remove seal screw when the circuit is live in a hazardous area.
ii. Remove span pushbutton seal screw.
iii. Using a 2mm or smaller Allen key, depress the pushbutton for a ½ second.
iv. Release pushbutton for a ½ second.
v. Depress the pushbutton again for a ½ second and release.
The SPX has now adjusted the URV 20 mA point to match the pressure applied.
6.8 RERANGING VIA HART
Rerange LRV (4)
This is the pressure at which the transmitter will output 4 mA as entered directly by the user. Changing
the LRV affects the transmitter span so the is range is limited by the minimum span value found in Fast
Key (1,4,1,5)
Rerange URV (5)
This is the pressure at which the transmitter will output 20 mA as entered directly by the user. This
range is limited by the minimum span value found in Fast Key (1,4,1,5)
Rerange LRV By Applying Pressure (1,2,5,1,1,1,1)
This is done by applying a known pressure and initiating the procedure so that the transmitter adopts
the pressure as the 4 mA point.
Note: This should only be performed with a Calibrated Pressure Source.
Rerange URV By Applying Pressure (1,2,5,1,1,1,2)
This is done by applying a known pressure and initiating the procedure so that the transmitter adopts
the pressure as the 20 mA point.
Note: This should only be performed with a Calibrated Pressure Source.
Recall Factory Trim (1,2,5,3)
This is used to restore the Zero, Lower, and Upper Trim to the Values as set from the Factory.
R-Cal Set % (1,2,5,1,4,1)
This is used on versions with a Rcal. By activating R-Cal, the output will be set to the percentage of span
set by this function. Default is 80%. Setting Rcal to 0%, disables the Rcal function.
Damping (1,3,5)
The damping time constant affects the speed with which the primary output signal reacts to changes in
pressure as shown in the figure on the following page. Damping is off by default but values between 0
and 30 seconds can be set using the handheld communicator. The damping value must be entered in
integers. If non-integers are entered, the system rounds to the next integer.

Local Actuator Disable (1,4,3,6)
Local zero and span actuators can be disabled using the HART handheld communicator function
“Local Push-buttons.” When turned off, the software Lock Out prevents changes to transmitter range
points via the local zero and span actuators. With local Push-buttons disabled, changes to configuration
are still possible via HART.
Status (1,2,1,2)
Reads Device Status from SPX.
PV Unit (1,3,2)
The pressure unit defines the unit of measure that the pressure-specific parameters are transmitted in.
The SPX can be configured in the engineering units of psi, Bar, MPa, and kgf/cm² or as a percentage of
Full Scale (FS). After selecting a new pressure unit, all entries for pressure are recalculated to the new
unit, using the following conversion rules:
1 psi = 0.068947 Bar = 0.0068947 MPa = 0.070309 kgf/cm²
Tag (1,3,1)
An inventory “Tag” identification number may be stored in transmitter memory (8 characters
maximum). Software tag is a single question mark by default.
Descriptor (1,3,4,2)
A 16 character text can be entered for further description of transmitter e.g. location, function, position,
etc.
Message (1,3,4,3)
A 20 character message can be set and displayed on the HART Communicator.
SV Electronics Temperature (1,1,7)
Temperature measured on the Electronics Assembly is used for reference and factory diagnostics only.
Poll Address (1,4,3,3,3)
Use in Multidrop mode allows more than one transmitter (up to 15) on a single loop. If this value is
other than zero, the transmitter is in Multidrop mode. An example of Multidrop mode would be a

group of HART devices wired in parallel on a single powered loop and each device being assigned a
unique Poll address (1-15). The HART communicator would prompt for the individual address of the
transmitter to communicate with and would only poll that specific device. All others would remain
unchanged. Note: Analog output is set to 4mA when in multi-drop mode.
Burst Mode (1,4,2,3,1)
When the SPX-T is used in Burst Mode, the transmitter outputs one-way digital communications from
the transmitter to the Host. Communication rate is faster since the transmitter does not have to be
polled to send data. Information transmitted in Burst Mode includes Pressure Variable, Analog Output
value, Pressure in % of range. Access to other information can still be obtained through normal HART
Comms.
6.9 RESETTING TO FACTORY DEFAULT SETTINGS
The factory settings for the sensor (including zero and span) can be restored if they are changed
inadvertently using the Zero/Span Actuators or the HART communicator. The list of parameters
restored is shown below.
Make sure Control System is in Manual mode. Temporary loss of Loop Output during
Electronics Re-boot may occur.
To reset the sensor using the actuators, use the following procedure:
i. Do not remove seal screw when the circuit is live in a hazardous area.
ii. Remove zero and span pushbutton seal screws.
iii. Using a 2mm or smaller Allen key, depress the pushbuttons for a ½ second.
iv. Release pushbuttons for a ½ second.
v. Depress the pushbuttons again for a ½ second and release.
At this point, the LRV and URV will be set to factory defaults.
