Important Information
1. Introduction
The 876PH Intelligent Transmitter converts pH, ORP, or ISE measurements to a 4 to 20 mA
output signal with a superimposed HART digital signal for remote configuration and monitoring.
A human/machine interface is integral to the device and provides simplified menu-driven
configuration, calibration, status, and diagnostic procedures.
Two electronic configuration options are available for the 876PH transmitter: 876PH-T and
876PH-S Model Code selections.
876PH-T Model Codes include HART communications and accept inputs from conventional
analog pH, ORP, ISE, or pre-amplified analog pH or ORP sensors.
876PH-S Model Codes include HART communications, but are dedicated for use with Foxboro
“Smart” pH sensors, specifically the Foxboro PH10-*S Model Code sensors and Foxboro PH12****S Model Code sensors (collectively referred to as Foxboro smart pH sensors in the remainder
of this document). The Foxboro smart pH sensors contain integral, digital electronics and
communicate digitally with the 876PH-S transmitter. Non-volatile memory in the Foxboro smart
pH sensors stores calibration parameters, date of manufacture, serial number, sales order number,
model code, slope, asymmetry, aging, remaining lifetime (-S only), and response time of the
sensor. Thus, a sensor calibrated on an 876PH-S transmitter or computer in a lab or instrument
shop can be transferred to an 876PH-S in a plant or field location without requiring re-calibration
at the point of use. A real-time clock enriches the history log of the 876PH-S transmitter.
876PH transmitters support remote configuration with a HART hand-held communicator or
PC-based configurator. The LCD indicator can display one, two, or three measurement variables.
Two levels of configurable passcode protection are standard. Two configuration programs can be
stored in the 876PH-T version and restored at any time to facilitate a quick and easy change to a
presaved configuration.
NOTE
Unless otherwise noted, information in this document pertains to all 876PH models.

2. Quick Start
Your 876PH Transmitter is a 2-wire transmitter. As such, it transmits output over the same two
wires through which it receives power. Connect this power/output signal to the power terminals at
the left of the printed wiring board inside the faceplate of your transmitter and the signal from
your measurement sensor to the corresponding numbered terminals at the top of the terminal
board. See Figure 1 and Figure 2
To access these terminals, remove the four screws in the corners of the bezel/keypad and open the
hinged bezel/keypad downward.
NOTICE
HAZARD OF EQUIPMENT DAMAGE
The bezel/keypad does not open a full 180°. Do not press on it while wiring.

Checking Transmitter Configuration
Enter the Configuration mode by pressing the Function key and then the Config key. At the
prompt, enter the passcode and press ENTER.
NOTE
The factory default passcode for both the Administrator and User is 0800.
Using the arrow keys, you can step through the current product configuration. Configuration
Structure Diagrams for 876PH-S and 876PH-T can be found in Appendix A and Appendix B,
respectively. The factory default values are listed in Appendix C. The values in your transmitter as
delivered will differ from these if a non-default configuration was specified in your order. A User
Configuration column is provided in the table in Appendix C where you can make any notations
you wish about your specific configuration.
When viewing these values, check that the Buffer Set parameter configured in your transmitter
matches the buffer(s) you intend to use in calibrating your device.
Calibration
After wiring your transmitter and checking/changing the configuration, perform a 2-Point
calibration. The calibration procedures for 876PH-S and 876PH-T are listed below.
Calibration Procedure for 876PH-S
When a Foxboro smart pH sensor is connected to the 876PH-S, its most recent calibration data is
uploaded to the transmitter. That calibration data may have come from performing a calibration
using an 876PH-S transmitter, as described below, or by performing a calibration using the
Foxboro smart pH sensor PC interface and DTM, as described in the PH10 or PH12 instructions
(see Table 1, page 16).
To enter the Calibration mode, press the FUNCTION key and then the CAL key. Enter your
password if prompted and press ENTER. The Calibrate menu option displays. Press ENTER to
view and edit the calibration parameters listed below (mA Cal, etc.), or press the Down arrow key
once to access the Calibrated By menu to enter the name of the person doing the calibration and
the calibration day, month, and year.
Calibration Procedure for 876PH-T
To enter the Calibration mode, press the Function key and then the Cal key. At the prompt,
enter the passcode and press ENTER. Next, enter the calibrator’s name. In the 876PH-T
transmitter, also enter calibration day, month, and year, pressing ENTER after each. Select Manual
or Smart. Then select Measurement from the Calibrate screen and follow the prompts for a 2point calibration to calibrate your transmitter. At the end of a successful calibration, no alerts will
be present in the transmitter.
19
MI 611-262 – July 2017
2. Quick Start
Calibration Incomplete
If a calibration is performed incorrectly, the entered value changes to black on the 876PH local
display and the Help key indicates what went wrong, for instance Calibration Incomplete.
Basic Operation in Measure Mode
Measure is the normal operating mode of your transmitter. One, two, or three measurements can
be displayed depending on the configuration. When the display is configured for single line
measurements, the value and unit are usually displayed. Any measurement can be temporarily
scrolled onto the display by using the Up and Down arrow keys. The display returns to the
configured values when you press the Function key and then the Measure key or when the
configured timeout period expires. When the transmitter is in Hold state, a Hold indication
appears in the upper right of the title bar as shown in Figure 4. If there is an alert, a flashing alert
symbol is displayed. If in Measure, Status, or Diagnostic mode, the word ALERT also flashes in the
lower left of the display. When you press the Function key, the function indicator is displayed.

NOTE
When a Foxboro smart pH sensor is connected to the 876PH-S transmitter with the
power already on, sensor data will be uploaded to the transmitter, which may take up
to one minute. If a sensor is already connected to the transmitter when it is powered
up, the transmitter will check to see if that sensor is the same one that was last
connected and if its data has not changed. If it is the same sensor with the same data,
the transmitter uses cached data for immediate operation.
NOTE
When changing from one Foxboro smart pH sensor to another, wait for the 876PH-S
transmitter to display a Sensor Disconnected message before connecting the new
sensor. Do not use a switchbox to change sensors as this will not allow adequate time
for the Sensor Disconnect message to appear on the transmitter.

4. Installation
Write Protection Jumper
Your transmitter has write protection capability which meets the security requirements of ISAS84.01-1986 for use in safety shutdown systems. This means that the local display and remote
electronics can be prohibited from writing to the electronics. Write protection is set by moving a
jumper that is located on the printed wiring board behind the front panel. To activate write
protection, open the front panel and place it in the ‘protect’ position. See Figure 9. In the ‘Not
Protected’ position, writing to certain functions can be limited by passcode protection.

Auto Scrolling Text on the Display (876PH-S only)
Some of the lines of text are too long to be fully shown on the display. These lines appear to be
truncated on the display. The Auto Scroll feature allows a subset of the lines to have the capability
to scroll, so that you can read all the text. In general, the header, footer and current selection
(which is surrounded by a box) can scroll as needed (see Figure 17).

The other lines do not scroll, even if the text is truncated.
Auto Scroll is enabled by default, but you can enable or disable it at any time. If enabled, any of
the scrolling lines that are too long to appear on the display begin to scroll from left to right after
a brief pause. All lines that scroll move at the same rate. As each line is fully scrolled, it snaps back
to its initial position on the display. Once all lines are fully scrolled and have snapped back to their
initial position, scrolling stops. If you want to see the lines scroll again, simply choose another
selection on the screen, and then choose your initial selection to start auto scrolling again.
Figure 19 shows two English screens. The screen on the left shows an Advanced Configure screen.
The Header line needs to be scrolled to be fully displayed (see red arrow). The screen on the right

Auto Scroll stops immediately when you make a selection using any of the controls.
See “Auto Scroll (876PH-S only)” on page 70 for information on how to enable/disable this
feature.
Passcode Access
Two levels of protection are available. Administrator (Admin Code) access permits changing the
parameters in Configuration as well as specifying the parameters that are accessible to users with
User Code access. User (User Code) access permits changing and viewing those areas specified by
the administrator. Both the Admin Code and User Code are 4-digit passcodes. The passcodes may
or may not be the same. They are set as part of configuring the instrument.
Upon entering the Configuration, Calibration, or Hold mode, you may be prompted to enter a
passcode. To exit, select another mode.
NOTE
Every passcode entry is added to the history log.
If entering Calibration or Configuration mode and you enter the correct passcode, the transmitter
responds in one of three ways depending on how Automatic Hold is configured. If Automatic
Hold is configured Off, the display indicates that the transmitter is not in Hold mode. Press
ENTER to continue. If Automatic Hold is configured Present, the display indicates that hold is
engaged, but that outputs are held at the present level. It then unlocks the mode. If Automatic
Hold is configured Manual, the display briefly displays Hold Engaged and then unlocks the
mode.
The initial factory default value for both Administrator and User passcodes is 0800.
To bypass the passcode, the administrator must configure a passcode of 0000.

Timeout
If there are no key presses within the configured timeout period, the transmitter discards all
changes and reverts to Measure mode. You can also return to Measure mode by pressing the
FUNCTION key and then the MEASURE key. If in Configuration or Calibration mode and the
automatic hold feature was employed, the output becomes live when the transmitter times out.
The timeout feature can be turned off in Configuration mode.
Viewing and Changing Data
In the Configuration, Calibration, Hold, and Diagnostic modes, you need to move through a
structure of parameters (using the Arrow keys and ENTER key) to view and/or change the value of
a particular parameter. Structure diagrams, located in Appendix A, will aid you in doing this.
NOTE
1. The Up and Down arrow keys scroll through a menu in either direction.
2. Using the Function key with the Up and Down arrow keys takes you to the top
and bottom of a menu respectively.
3. If a menu selection is invalid, you will see a selection in inverted text (white letters
on black background). This choice is not selectable. It will disappear after you
make your choice. To keep the selection, use the FUNCTION then Back keys.
The following example will show you how to use the controls to move through the menu
structure for the 876PH-S. The keystrokes are similar for 876PH-T (see the Configuration menu
structure in Figure 59 for details.) The example shows how to configure temperature features. For

Measure Mode
Measure is the normal operating mode of your transmitter. Depending on your configuration, the
display can show 1, 2, or 3 measured values. In Configure mode, you can also configure what to
display on each line. The choices are the (pH, ORP, or ISE) measurement, the absolute value of
the measurement in millivolts, the temperature, and the analog output (4 to 20 mA). The units
are shown with the measured values.
Any measured values can be temporarily scrolled onto the display by using the Up and Down
arrow keys. See Figure 22. The display returns to the configured values when you press the
FUNCTION key and then the MEASURE key or when the timeout period expires. When the
transmitter is in Hold, a hold indication appears in the upper right of the display. If there is an
alert, an alert symbol is displayed in the title bar and, if in Measure, Status, or Diagnostic mode,
the word ALERT flashes in the lower left of the display. See Figure 4.

5. Operation Via Local Display
Up to five calibration selections are available; mA Cal, Measurement, Temperature, ORP, and
ORP Restore. See Figure 26 for 876PH-S and Figure 27 for 876PH-T.
For 876PH-S only:
When a Foxboro smart pH sensor is connected to the 876PH-S, its most recent calibration data is
uploaded to the transmitter. That calibration data may have come from performing a calibration
using an 876PH-S transmitter, as described below, or by performing a calibration using the
Foxboro smart pH sensor PC interface and DTM, as described in the PH10 or PH12 instructions
(see Table 1, page 16).
To enter the Calibration mode, press the FUNCTION key and then the CAL key. Enter your
password if prompted and press ENTER. The Calibrate menu option displays. Press ENTER to

Measurement Calibration
Measurement Calibration is used for pH, ISE, or ORP as your Measurement.
NOTE
To achieve a multipoint calibration that helps ensure a specified accuracy throughout
the entire range capability of the instrument, it is recommended that calibration
points be at least 2 pH units apart.
To perform a measurement calibration, select Measurement and press ENTER.
1. At the prompt, enter the number of calibration points from 1 to 5.
2. At the next prompt, select the standard as Manual, Smart, or Process.
Manual presumes no knowledge by the transmitter of the calibration solution being
used. You must enter the exact known value at the calibration temperature. No
temperature compensation is applied in the firmware.
Smart presumes use of the configured calibration standards. Solutions are recognized
automatically so there is no need for you to enter a known value. The temperature
response for the recognized solution is used in the calibration. If none of the solutions
provide a unique match (±0.5 pH of nominal buffer value), the calibration reverts to a
Manual calibration.
Process presumes a grab sample of the process. You must enter a known value at the
reference temperature (usually 25°C) from laboratory measurements. The configured
application temperature compensation is applied.
NOTE
Process only appears in the menu if you selected Ammonia or Custom as your type of
temperature compensation (See “Temperature Compensation” on page 62).
3. At the prompt, put the sensor in the solution and press ENTER.
NOTE
If the Foxboro smart pH sensor and 876PH-S transmitter are in use and this step is
being carried out in the second buffer solution, this step will be used to measure
sensor Calibration Response time. Therefore, it is important to press ENTER as soon as
possible after placing the sensor in the buffer.
4. If you selected Manual in Step 2:
a. Measurement/Temperature is temporarily displayed while process is stabilizing.
b. At the prompt, enter the known measurement value at the current temperature
and press ENTER.
5. If you selected Smart in Step 2,
a. Measurement/Temperature is temporarily displayed while process is stabilizing.
b. You do not need to enter the known pH values as you did in Manual.

Configuration Mode
NOTE
1. Configuration mode may be protected. See “Passcode Access” on page 39.
2. If using the Automatic Hold feature, the outputs are held at the present level or a
predetermined level. Returning to Measure mode releases the hold.
3. The details of the Configuration menu structure are provided in Appendix A for
the 876PH-S and in Appendix B for the 876PH-T. Each section below references
the appropriate figure in the Appendix A or B to illustrate the menu structure for
your product.
Configuration is the process of establishing functional capability in the transmitter firmware for
your application. This section helps you to systematically determine and configure the value or
status of each parameter required for your application. It is recommended that you make
configuration changes from the beginning of the menu structure forward. This is because menus
are forward referencing meaning that if you start at the beginning and work to the end, you
achieve a valid configuration. Also, the transmitter validates the configuration when attempting to
exit configuration and directs you to any invalid parameters.
To enter the Configuration mode, press the FUNCTION key and then the CONFIG key. After
gaining access to Configuration, the first category in the top level configuration structure (Temp
Units for 876PH-S and Sensor for 876PH-T) is displayed. To view or change another
configuration category, press the Up or Down arrow key. When you have located the desired
category, press the ENTER key. Each category of parameters is shown in subsequent structure
diagrams.
NOTE
If there are no key presses within the configured Timeout period, the transmitter
reverts to Measure mode and all changes are lost.
Temperature Units
Refer to Figure 39 for 876PH-S and Figure 62 for 876PH-T.
Temp Units has its own menu item for the 876PH-S. That same choice is located under the
Temp Conifg menu for 876PH-T.
Specify Temp Unit as degC or degF. References to temperature appear in the specified units
within the transmitter software.
Analog Out(PV)
Refer to Figure 40 for 876PH-S and Figure 64 for 876PH-T.
This section of the structure enables you to specify what measurement the analog output reflects
and the minimum and maximum range values for the output just specified. It also enables you to
specify the measurement for the HART secondary, tertiary, and quaternary measurements.
First, specify AO Source Measurement as Measurement, Temperature, ORP, Absolute,
Glass Resistance, Reference Res (reference junction resistance), or ATC Resistance.
56
5. Operation Via Local Display
MI 611-262 – July 2017
NOTE
AO Source Measurement selections are limited by your configuration of sensor and
diagnostics.
Next, in Lower Value enter the value of that measurement that produces an output of 4 mA and
in Upper Value, the value of the measurement that produces an output of 20 mA. The lower
and upper values must differ by a minimum amount. That minimum span amount is 0.5 pH for
pH measurement, 32 mV for ORP measurement, and the amount shown in Table 7 for ISE
measurement.

Then specify the measurements of HART SV, HART TV, and HART QV as Measurement,
Temperature, ORP, Absolute, Glass Resistance, Reference Res, or ATC Resistance.
The secondary measurement is frequently configured to temperature, the tertiary measurement to
Absolute, and the quaternary measurement to ATC Resistance.
Advanced Configuration
The Advanced Configuration section of the menu structure only applies to 876PH-S, but most of
the parameters in this section also apply to 876PH-T as noted in the text describing each
parameter.
Refer to Figure 41 for 876PH-S.
This section of the structure enables you to specify the following advanced configuration
parameters:
♦ Measurement Configuration
♦ Temperature Configuration
♦ Temperature Compensation
♦ Measurement Display
♦ AO Failsafe
♦ HART Digital
♦ Diagnostics
♦ Config Timeout
♦ Transmitter Tags
♦ Passcode Access

Refer to Figure 60 for 876PH-T.
This section of the configuration structure begins by asking you to specify your type of
measurement as pH, pH and ORP, ISE Concentration, or ORP.
NOTE
The 876PH-S transmitter does not have the Sensor configuration option. The
transmitter reads the type through the Smart sensor
NOTE
Whenever the Measurement type or Electrode is entered and saved, any user
calibration is erased and the transmitter reverts to an ideal sensor calibration. For each
Foxboro smart pH sensor, each one specifies its own measurement type and it is not
configurable.
pH (876PH-T Only)
If you selected pH, you must specify the electrode as Glass, Antimony, or Other. Glass sets the
isopotential point at 7 pH. Antimony sets it at 1 pH. Other allows the isopotential point to be set
manually from -2.0 through +16.0 pH. If you selected Other, you must also enter the Slope.
Next specify the temperature (RTD) type as 2-Wire Pt 100 Ω, 2-Wire Pt 1000 Ω, 3-Wire
Pt 100 Ω, 3-Wire Pt 1000 Ω, or Balco 3 kΩ.
For the Smart version, the RTD is 1000-Ω only and is not configurable.

pH and ORP (876PH-S)
Simultaneous pH and ORP measurements can be made with the 876PH-S using the
combination pH/ORP versions of the PH12, which are PH12-A**S, PH12-B**S, and
PH12-C**S.

MI 611-262 – July 2017
5. Operation Via Local Display
pH and ORP (876PH-T)
This allows simultaneous measurement of both pH and ORP using a single reference electrode.
Ideally, this would use a single sensor having all three required electrodes, but could use two
distinct sensors. Connect the pH electrode to terminal 3, the ORP electrode to terminal 4, and
one reference electrode to terminal 5.
When using this configuration, the ±2000 mV range applies independently to both terminals 3
and 5 relative to terminal 4. In other words, pH mV – ORP mV must remain within the
±2000 mV range.
If you selected pH and ORP, you must specify the pH electrode as Glass, Antimony, or Other.
Glass sets the isopotential point at 7 pH. Antimony sets it at 1 pH. Other allows the
isopotential point to be set manually from -2.0 through +16.0 pH. If you selected Other, you
must also enter the Slope.
Next specify the temperature (RTD) type as Balco 3 kΩ, 2-Wire Pt 100 Ω, 2-Wire Pt 1000
Ω, 3-Wire Pt 100 Ω, or 3-Wire Pt 1000 Ω. See Table 8.
NOTE
When using non-Foxboro sensors for pH and ORP measurement, see the note on the
wiring diagram (Figure 9).
ISE Concentration (876PH-T Only)
If you selected ISE Concentration, you must configure the following:
1. Specify the ion polarity (Electrode) as Positive or Negative. A positive ion
selective mV value becomes more positive as the concentration increases (for example,
Na+, K+). A negative ion selective mV value becomes more negative as the
concentration increases (for example, F–, S–2). For fluoride measurements, this
parameter must be set to negative.
2. Enter the Isopotential point from 0.0001 to 9999.9 in concentration units
selected in “ISE Concentration (876PH-T Only)” on page 61.
3. Specify the Valence as Monovalent (for example, F–) or Divalent (for example, S–
2).
4. Specify the temperature (RTD) type as 2-Wire Pt 100 Ω, 2-Wire Pt 1000 Ω, 3Wire Pt 100 Ω, 3-Wire Pt 1000 Ω, or Balco 3 k Ω. See Table 8.
ORP (876PH-S)
With the PH12-S ORP sensor, no temperature type need be selected.
ORP (876PH-T)
If you selected ORP, you only have to specify the temperature (RTD) type. The choices are Balco
3 kΩ, 2-Wire Pt 100 Ω, 2-Wire Pt 1000 Ω, 3-Wire Pt 100 Ω, or 3-Wire Pt 1000 Ω. See

Measurement Configuration
Refer to Figure 43 for 876PH-S and Figure 61 for 876PH-T.
The structure of Meas Config is dependent on the type of measurement being made.
pH (876PH-S and 876PH-T)
If your Measurement selection is pH, specify your pH Resolution as 0.1 pH or 0.01 pH.
Then enter the Damping response time (for 90% recovery from a step change). You can enter a
time up to 300 seconds expressed in seconds. To increase damping, use a higher response time.
Damping applies only to compensated measurement data, not to temperature or absolute data.
pH and ORP
If your Measurement selection was pH and ORP, specify your Resolution as 0.1 pH or 0.01
pH.
Then enter the Damping response time (for 90% recovery from a step change). You can enter a
time up to 300 seconds expressed in seconds. To increase damping, use a higher response time.
Damping applies only to compensated measurement data, not to temperature or absolute data.
ISE Concentration (876PH-T Only)
If your Measurement selection was ISE Concentration, specify the ISE Units as ppb, ppm, %, or
Custom.
Next, specify the ISE Scale as 0.9999, 9.999, 99.99, 999.9, or 9999.
If you selected Custom as your ISE Unit, you must name (text) that unit in Custom Units.
Then enter the Damping response time (for 90% recovery from a step change). You can enter a
time up to 300 seconds expressed in seconds. To increase damping, use a higher response time.
Damping applies only to compensated measurement data, not to temperature or absolute data.
Temperature Configuration
Temp Unit (876PH-T only)
NOTE
Temp Unit displays under the Temp Config selection for 876PH-T. Refer to
Figure 62 for 876PH-T.
Temp Unit has its own menu selection for 876PH-S. Refer to Figure 39 for
876PH-S.
Specify Temp Unit as degC or degF. References to temperature appear in the specified units
within the transmitter software.
Temp Mode
Refer to Figure 44 for 876PH-S and Figure 62 for 876PH-T.
Specify the Temp Mode as Auto or Manual.
61
MI 611-262 – July 2017
5. Operation Via Local Display
In Auto mode, the temperature follows the temperature input RTD and you can set a
temperature alert signal value (Alert Temp), in case the RTD alerts, at the temperature at which
you expect the process to be operating.
In Manual mode, the temperature can be set at a fixed temperature value (Manual Temp) and
resistance inputs on the temperature terminal are ignored.
Temperature Compensation
Refer to Figure 45 for 876PH-S and Figure 63 for 876PH-T.
This section of the structure asks you to specify the temperature compensation if you are
measuring pH or ISE.
NOTE
This section does not appear if you selected ORP as your Measurement.
If pH or pH and ORP was chosen as your Measurement, specify Standard, Ammonia, or
Custom. Standard assumes a glass or antimony electrode and applies the Nernst equation. The
nominal temperature compensation range is -30 to +200 ° C (-22 to +392 ° F). Ammonia
compensates for traces of ammonia in addition to the standard compensation. Custom allows you
to specify particular solution characteristics into the transmitter’s memory. When using Ammonia
or Custom compensation, all measurements are corrected back to a reference temperature
measurement value. Therefore, you are asked to specify a reference temperature. The reference
temperature (Reference Temp) can be set within the temperature compensation range. For
Custom, a number of points needs to be specified. The number of points (Points) can be
specified from 2 to 21 points. Each point specifies a value at a certain temperature. The
temperatures can be set from -30 through + 200°C (-22 through +392°F). The temperature units
were specified in the previous section. The values can be specified within the current scale.
NOTE
The temperature values must be entered in increasing or decreasing order. If an invalid
point is entered in the table, the value is highlighted in reverse text. Also, if a valid
point which creates an invalid slope is entered, the value is highlighted in reverse text.
In either case, no alert message is displayed, but you cannot continue until the value
in reverse text is replaced with a valid value.
If ISE Concentration was chosen as your Measurement, you must specify Standard or
Custom. Custom causes you to specify a reference temperature and a number of points to plot a
compensation curve. The procedure is described immediately above.

Refer to Figure 47 for 876PH-S and Figure 66 for 876PH-T.
NOTE
The AO Failsafe parameter is not available with multidrop communication.
A fail-safe output is delivered for those diagnostic alerts that have been configured On as well as
other alerts. The AO Failsafe section of the structure enables you to specify the analog output
under these alert conditions.
In AO Failsafe, select Fail Low to drive the analog output to 3.6 mA; select Fail High to drive
the analog output to 22 mA; select Off to omit this feature (continues to follow the
measurement). If Off is selected, you must continue to monitor alerts using the HART protocol.
NOTE
1. Configure AO Failsafe to protect your process in case of an alert.
2. A severe loss of operating capability that is detected by an 876PH-S transmitter
(for example, an Incomplete firmware load), will result in a fail-safe output of 22
mA. This protective feature is not configurable.

Diagnostics
Refer to Figure 49 for 876PH-S and Figure 68 for 876PH-T.
This section of the structure allows you to configure alert messages that can appear on your
display. In Diagnostics, you can elect to enable (On) or disable (Off) all of the diagnostics or
each of the following individually: Leakage, ATC Short, ATC Open, Comp Range, Meas Range,
Low Slope, Sensor Service Prediction, Preamp, Reference Coating, Broken Glass,
and Aging. Each of these is discussed below. A typical approach is to initially disable all of the
messages and to enable selected messages later when you find out that you require them. An alert
symbol is displayed if a particular diagnostic is enabled and the alert occurs. If the diagnostics
detects a alert, the analog output goes to the failsafe value if AO Failsafe was configured On (see
Figure 47).
Leakage
This diagnostic detects and reports a problem of severe liquid leakage into the sensor which causes
an ATC short to solution ground. The diagnostic can be enabled or disabled.
ATC Short, ATC Open
This diagnostic detects and reports a problem if the resistance of the temperature compensator is
greater or less than the expected resistance of the device configured. The diagnostic for each can
be enabled or disabled.
Comp Range
This diagnostic detects and reports that the measurement or temperature is outside the range
configured. The diagnostic can be enabled or disabled.
Meas Range
This diagnostic reports that the measurement is over or under the analog output range that is
configured. The diagnostic can be enabled or disabled.
Low Slope
This diagnostic detects and reports a problem usually associated with an aging glass electrode. It
appears after a multipoint calibration in buffer solutions when the Nernst slope of the sensor
becomes less than the user set limit. The limit can be set from 0 through 100 percent. It applies to
the slope between any two points. The diagnostic can be enabled or disabled.

MI 611-262 – July 2017
5. Operation Via Local Display
NOTE
1. This message does not appear for ORP measurement.
2. In Diagnostics, Low Slope applies to the slope between any two points. In Status
mode, the only slope shown is that closest to the isopotential point. Therefore it is
possible to show an alert in Diagnostics mode but not in Status mode.
Sensor Service Prediction (876PH-S Glass Electrode Only)
The 876PH-S Transmitter is capable of predicting the number of days remaining before a
Foxboro smart pH sensor will require service in the form of cleaning, recalibration,
reconditioning, or replacement (see MI 611-205 for PH10-*S or MI 611-214 for PH12-****S).
The prediction is based on analyzing the trend in slope values stored in the Sensor History Log
each time the sensor is calibrated, taking into account the temperature history of the sensor, and
estimating the number of days remaining before the slope drops below a user-selectable Prediction
Slope Limit. When the number of days remaining before the predicted slope will fall below the
limit is less than a user-settable Advance Notice period, a Service Now warning is displayed.
The Sensor Service Prediction feature has the following outputs:
Prediction Status Indication in
Status Menu
Definition
OK
Most recent calibration slope is greater than 90%.
Days Remaining Displayed
Most recent calibration slope is less than 90%. Predicted slope is greater
than the Prediction Slope Limit.
Days Remaining Displayed;
“Service Now” alert in
Diagnostics screen.
Number of days before the predicted slope will fall below the Prediction
Slope Limit is less than or equal to the Advanced Notice period.
Sensor Service Prediction is most effective when a sensor remains in a particular application or
measuring point throughout its service life. When a sensor with History Log entries from one
application is moved to a different application with different process composition and
temperature conditions, Sensor Service Prediction will require a period of time to collect historical
data in the new application before it will provide a reliable prediction.
NOTE
When a smart sensor is first connected to the transmitter, it may take up to one
minute for the Sensor Service Prediction diagnostic to update.
Preamp (876PH-T Only)
This diagnostic reports an alert on the preamplifier (in the sensor or junction box). It appears if
the preamplifier draws too much power. A shorted preamplifier causes the transmitter to cease
functioning.
NOTE
If the transmitter is unresponsive, disconnect terminal 6. If the transmitter begins to
function, it is a confirmation that the detected problem is in the preamplifier.

MI 611-262 – July 2017
Reference Coating
This diagnostic reports an increase in reference junction resistance possibly resulting from a fouled
reference junction. The diagnostics check the resistance against solution ground.The message
appears if the resistance is greater than the user set limit. The limit can be set from 0 through
200 kΩ. The diagnostic can be enabled or disabled.
Broken Glass
This diagnostic reports an alert in the resistance of a glass electrode in the sensor. Resistance of a
glass electrode is checked versus solution ground. An alert appears if the resistance is less than user
set limit. The Glass Lo Limit value may be entered between 0.10 and 1.10 MΩ. You can also
specify a Cutoff temperature above which this feature is disabled. Cutoff can be set between 30 and +200. The resistance of a glass bulb decreases (roughly is halved) for every 10°C increase
in temperature.
NOTE
The diagnostic is disabled unless the electrode is specifically pH glass.
Aging
This diagnostic reports an aging glass electrode. The message appears after a multipoint
calibration in pH buffer solutions when the Nernst slope of the sensor closest to the isopotential
point has decreased sequentially five times. The diagnostic can be enabled or disabled.
Auto Hold
Refer to Figure 50 for 876PH-S and Figure 69 for 876PH-T.
The Auto Hold section of the structure enables you to select automatic hold to automatically
activate the Hold feature each time you enter Calibration or Configuration mode. In Auto Hold,
select On Present to hold all output values at their current level; On Manual to set all output
values at desired levels; or Off to omit this feature.
NOTE
If you select On Manual, go to Hold mode to change the values.
Config Timeout
Refer to Figure 51 for 8786PH-S and Figure 70 for 876PH-T.
The Config Timeout section of the structure enables you to specify the time in which the
instrument brings you back to the Measure mode from another mode when no keyboard input
has occurred. In Measure mode, Timeout also controls the time to view a display other than that
configured in “Display Format” on page 63 that has been temporarily scrolled into view. Timeout
can be configured to Always Timeout, timeout in online modes only (Online Only) or Never
Timeout. The Always Timeout selection is recommended.
The timeout can be configured separately for front panel (Front Panel) and (HART
Communications) operation. The time can be specified from 30 through 999 seconds.

Restore Configuration
Refer to Figure 58 for 876PH-S and Figure 74 for 876PH-T.
Configuring your transmitter involves the setting of many parameters specific for the application.
In some cases, you may wish to employ the transmitter for more than one application (at different
times). Rather than having to change several parameters, the 876PH allows you to save up to two
unique and complete configuration profiles. The 876PH-T version also includes the calibrations
associated with each profile. The 876PH-S version uses only the calibration stored in the sensor,
and this is unaffected by the profiles. Either of these two profiles can be restored at any time to
facilitate a quick and easy change of the transmitter to a presaved configuration. In addition to the
two user profiles, the transmitter also includes a “factory default” configuration which allows you
to return the transmitter to its original factory configuration at any time. Refer to Appendix C,
“Configuration Table” for the factory configuration.
In Restore Config, select Restore User 1, Restore User 2, or Restore Factory and at
the question Restore User 1 Configuration?, Restore User 2 Configuration?, or
Restore Factory Configuration?, answer Yes or No.

History Log
History Log contains a set of logs of events for the transmitter. See Table 12. For a set of logs of
sensor events, see Sensor History below. Select History Log and press ENTER to view or erase the
transmitter history logs. Use the Up and Down arrow keys to select All History Logs, Calibration
Log, Alert Log, Operation Log. You can also select Clear History. however clearing the history log
requires entering your passcode.
All sensor-independent parameters in the 876PH-S transmitter can be configured without an
attached sensor. When the transmitter detects that a sensor has been connected, it automatically
uploads the most recent set of calibration and configuration data from the sensor. If a power cycle
occurs, the 876PH-S transmitter uploads the most recent complete set of calibration and
configuration data from a connected sensor.

Sensor History
Information pertaining to a specific Foxboro smart pH sensor is contained in its history log called
“Sensor History.” The 876PH-S transmitter is used for calibration and sensor configuration, the
history of which is appended to the Sensor History log (see Table 13).
The Foxboro smart pH sensors store data such as date of manufacture, serial number, sales order
number, model code, slope, asymmetry, aging and response time.

Suspend Alerts and Resume Alerts
Select Suspend Alerts to suspend the present alerts for one hour. The display asks for your
passcode. An incorrect passcode returns you to the start of the Diagnostic menu. A correct
passcode causes the prompt Suspend Alert? to be displayed. If you answer Yes, the message
Alerts Suspended is displayed. After either a Yes or No reply, the Diagnostic menu is
displayed. Each suspended alert is inhibited from reoccurring for one hour from the time the
Diagnostic mode is entered.
Select Resume Alerts to resume all suspended alerts.
Save User Configuration
Configuring your transmitter involves the setting of many parameters specific for the application.
In some cases, you may wish to employ the transmitter for more than one application (at different
times). Rather than having to change several parameters, the 876PH-T and 876PH-S versions
allow you to save up to two unique and complete configuration profiles. The 876PH-T also
allows you to save the profiles with the calibrations associated with each profile.
Either of these two profiles can be restored at any time to facilitate a quick and easy change of the
transmitter to a presaved configuration. See “Restore Configuration” on page 71.
Select Save Config 1 or Save Config 2 to save your configuration. The display asks for your
passcode. An incorrect passcode returns you to the start of the Diagnostic menu. A correct
passcode causes the prompt Save Config #? to be displayed. If you answer Yes, the message
Configuration Saved is displayed. If you answer No, the message displayed is Action
Cancelled.

6. Operation Via HART
Communicator
The DD menus for the 876PH-S and the 876PH-T are different. This chapter provides the
HART Online menus for both products.
NOTE
1. For HART communications, a 250 Ω load resistor must be present in the power
supply loop.
2. For proper communication with a HART Communicator, the communicator
must contain the proper DD for the 876PH Transmitter. This DD is available on
our website or any other authorized HART Foundation source.
3. The 876PH-T is device ID 1405 and the 876PH-S is device ID 140B.
4. If the DD shows “access restricted”, start over and re-enter the passcode.
Entering Modes
From the home menu, select the mode to be entered. If Save to Xmtr appears, it must be
handled before entering a different mode. If a passcode is required, select Enter Passcode
before accessing a new mode.
Saving Changes
Changes must be saved before going to another mode.
If the Send soft key appears on the screen, it must be pressed before saving changes.
Press Home, select Save to Xmtr. Answer the Save changes? question by selecting Yes or No,
and pressing ENTER. If invalid information was entered, the Fix Invalid Changes? question
appears. No discards all changes; Yes provides the title of the first parameter with invalid
information which must then be resolved.
NOTE
The Save soft key refers to a local communicator copy of the parameters, not the
transmitter's Save changes.
