(1054B pH only).
•
NEMA 4X (IP65) WEATHERPROOF CORROSION-RESISTANT ENCLOSURE.
•
NO BATTERY BACK-UP REQUIRED. Non-volatile EEPROM memory.
•
SPECIFIC PROCESS TEMPERATURE COMPENSATION for pH changes due to temperature (1054B pH only).
1.1 FEATURES AND APPLICATIONS
The Model 1054B Microprocessor Analyzers, with the
appropriate sensor, are designed to continuously measure and control pH, ORP, conductivity, percent concentration, ratio, resistivity, ozone, dissolved oxygen and total
free chlorine in industrial and municipal processes.
The Model 1054B is housed in a NEMA 4X (IP65)
weatherproof corrosion-resistant, flame retardant
enclosure suitable for panel, pipe or wall mounting.
All functions are accessed through the front panel
membrane keyboard which features tactile feedback.
Measurement data may be read at any time; however,
settings may be protected against accidental or
unauthorized changes by a user selectable security
code. The display indicates the measured value in
engineering units as well as temperature, alarm status, hold output and fault conditions.
The analyzer transmits an isolated current output which
is continuously expandable over the measurement
range for either direct or reverse action. A hold output
function is available for allowing manual control during
routine sensor maintenance. During hold mode the
output will be at a preset or last process value.
In the event of one of the following conditions, the
analyzer will drive the output to a preset value in addition to displaying a fault code. The Model 1054B pH’s
continuous self diagnostics alert the user to the following:
With automatic buffer recognition, the analyzer recognizes the buffers, then calculates the electrode slope
using stored pH-temperature curves for ten common
buffers.
Dual alarms are a standard feature on the Model
1054B and are programmable for either high or low
operation. Alarm 2 may be programmed to activate in
event of a failure detected by the continuous diagnostics. Both alarms feature independent setpoints,
adjustable hysteresis and time delay action. A dedicated interval timer with relay is also provided for chemical or ultrasonic cleaning.
The 1054B pH automatically compensates the pH
reading for process temperature changes. Automatic
or manual temperature compensation is keyboard
selectable. Additional process temperature compensation is available.
The Analyzer includes a 0.7 inch digital display available in LCD or LED format.
The Model 1054B can display the process temperature in °F or °C.

The Model 1054B pH Analyzer requires a preamplifier to con-
vert the high impedance pH glass electrode signal to a low
impedance signal. The preamplifier may be located in one of
three areas; in the pH sensor for best performance, in a remote
junction box when process temperatures exceed 80°C (176°F)
in submersion applications, or in the analyzer when the distance between the pH sensor and the analyzer is 4.5 meters
(15 ft) or less. The result is that the pH signal may then be reliably transmitted from the sensor to the analyzer using standard
shielded 4-wire instrument cable.
The Model 1054B pH measures over the full range of 0-14 pH.
The current output may be calibrated to represent any 1 to 14
pH span.
A two-point calibration is made by immersing the sensor in two
different buffer solutions and entering the pH values. When two
buffers are used, the microprocessor automatically calculates
the electrode slope which is used for self-diagnostics.This electrode slope can be read on the display and manually adjusted.
A one point process standardization is also easily accomplished
by entering the pH value of a grab sample.

SECTION 3.0
DESCRIPTION OF CONTROLS
3.1 KEYBOARD FUNCTIONS.
All functions of the 1054B are accessed through keyboard entry routines. The analyzer uses no switches or
potentiometers.
The four keys across the top row and the CAL (pH
only) and ENTER keys are dual function. One press of
the key will display the value of the function shown on
the lower portion of the key. A quick double press of
the key will display the value of the function shown on
the upper portion of the key. Each of these keys have
read functions that can be accessed without security
code entry. Each key also has a calibration or set function when used with the SELECT key. This function
requires entry of the security code when the security
feature is active. (Refer to Section 6.0 for keyboard
security.)
NOTE
When no key is pressed for a period of 60
seconds the analyzer will default to reading pH.

SECTION 4.0
CONFIGURATION
4.1 CONFIGURATION. This section details all of the
items available in the Set Mode to configure the
analyzer to a specific application.
4.1.1 Configuration Work Sheet. The configuration
work sheet for pH - Table 4-1 (or, in the case of ORP,
Table 4-2) should be filled out before proceeding with
the analyzer's configuration. This sheet gives a brief
parameter description, the factory setting, and a
space for user setting.
4.1.2 Set Mode. Display mnemonic SEt. Most of the
analyzer's configuration is done while in the Set
Mode. Please refer to Figure 4-1 for the layout of all
menu items for pH measurement. Refer to Figure 4-2
for the layout of all menu items for ORP measurement. All menu variables are written to the analyzer's
EEPROM (memory) when selected and remain there
until changed. As these variables remain in memory
even after the analyzer's power is removed, the
Model 1054B pH/ORP configuration may be performed prior to installing it.
1. Power up the analyzer. Only power input wiring is
required for analyzer configuration (Refer to
Section 2.4.1). The analyzer's display will begin
showing values and/or fault mnemonics. All fault
mnemonics will be suppressed while the analyzer is in Set Mode (the fault flag will continue to
blink).
2. Enter Set Mode. Pressing the ACCESS key twice
in rapid succession will place the analyzer in Set
Mode. The display will show SEt to confirm that it
is in Set Mode. It will then display the first item in
the Set Menu Ein. The analyzer is now ready for
user configuration.
NOTE
If LOC displays, the Keyboard Security
Code must be entered to access the Set
Mode. (Refer to Section 6.0.)
3. Analyzer variables can be entered in any order.
On initial configuration, however, it is recommended that the variables be entered in the
order shown on the work sheet (Table 4-1 - pH,
Table 4-2 - ORP). This will reduce the chance of
accidentally omitting a needed variable.

200 megohms, and as it ages the impedance increases because lithium ions (which carry current) in the
glass slowly get depleted by the process. If an electrode cracks, the impedance drops sharply, usually to
below 70% of the normal value.
The following are typical impedance values for new
Rosemount Analytical electrodes (Electrodes stored
over a period of time will have higher impedances).
Upon installation you can read impedance in megohms
under rES.
Sensor/Glass Megohms @
Type
30°C (86°F) when new
• General purpose, 30-100
HF, and high pH glass (GPLR)
• General Purpose
High Temp (GPHT) 50-90
• Ruggedized glass 200-300
For more information on these diagnostics and troubleshooting, refer to Section 8.0.
NOTE
Impedance diagnostic faults are not activated until the setpoint is continuously
exceeded for 30 seconds.
A. Calibration Warning. Display Mnemonic CAL.
Under this mnemonic you can select the percent
increase in impedance before a calibration warning
fault appears. For example, if the impedance is 400
megohms and the setpoint is 20% (factory setting), a
CAL warning will appear on the analyzer and it will go
into a fault mode when the electrode ages to 480
megohms. This diagnostic will reset after a buffer calibration. Configurable range: 20-200%. A setting of
zero disables this fault.
NOTE
The recommended process temperature
range for the CAL diagnostic is 15-90°C
(15-194°F.) (For low impedance glass it is
15-80°C (59-176°F). If ruggedized glass is
used and the preamp is not in the sensor,
the minimum recommended temperature
is 35°C (95°F).
If you want to use this feature as a warning yet not
upset your process, use Alarm 2 as a fault alarm (Refer
to Section 4.2) and set the default current output to non
(Refer to Section 4.8) to hold the output at the last
process value.
You may also get this fault if:
1. The electrode or junction becomes excessively
coated.
2. The electrode is not immersed in the process fluid.
If the electrode continues to remain out of solution
eventually the fault mnemonic OId will also appear
on the display. See part C.
B. Cracked Glass Diagnostic. Display Mnemonic SHt.
One way to tell that you have a broken or cracked glass
electrode is that the analyzer will read a constant value
(usually between 5.0-7.0 pH) in any process or buffer.
The other way is to note the impedance value. When a
crack occurs the mnemonic SHt will appear on the analyzer to indicate that the circuit is shorted, and the analyzer will go into a fault mode. Directions for SHt value
determination:
SHt ~ 70% of normal rES
Configurable range: 5-600 megohms. A setting of
zero disables this fault. Factory setting: 20 megohms.
NOTE
For low impedance glass, a broken electrode may not be detectable above 7075°C (158-167°F).
C. Worn Out Electrode. Display Mnemonic OId. This
mnemonic is used for programming the high impedance limit of the electrode. For example, if the setpoint
is 1000 megohms (factory setting), and the impedance rises above this value, the mnemonic OId will
appear on the analyzer and it will go into a fault mode.
The electrode is either worn out, severely coated, or
not immersed in the process fluid. Configurable
range: 200-1999 megohms. A setting of zero disables
this fault.
Recommended setpoints:
1. 1000 megohms for all glass except ruggedized
2. 1300 meghoms for ruggedized glass

6. Use the SCROLL (é) and SHIFT (ç) keys to
change the value, if desired.
7. ENTER the value into memory.
8. Press ENTER to return to the main Set Menu.
4.7 SOLUTION TEMPERATURE COMPENSATION
AND ISOPOTENTIAL POINT (Model 1054B pH
only). Display Mnemonic iSO. Used for applications
where the process' isopotential point (iPH) and temperature coefficient (tCO) are not standard. For normal
pH measurements these values should be: rPH = 7.00
(normal process pH), iPH = 7.00 pH, tCO = 0.00
pH/°C.
These values should only be changed for spe-
cial applications
.
Solution temperature compensation is designed to
correct for changes in the actual pH of a solution
caused by changes in dissociation with temperature.
During standardization (Section 5.4), if the sample pH
is greater than about 6.5 and the lab test is run at a
substantially different temperature than the process,
determine a value for tCO in pH/°C and enter that
value. The tCO should be determined over as narrow a
temperature operating range as possible.
The isopotential point is the pH value at which temperature changes do not affect the pH reading.
The analyzer method requires the user to enter the
normal process pH (rPH) and the temperature coefficient (tCO), then the isopotential point (iPH) will be calculated. Conversely, entering the normal process pH
and the isopotential point causes the temperature
coefficient to be calculated.
4.7.1 pH Measurement in High Purity Water with
Ammonia Present. The special characteristics of this
measurement require changing isopotential pH value
and temperature coefficient used by the Model 1054B
pH. The reference pH (rPH) is the user’s normal
process pH. The isopotential pH value (iPH) of high
purity water with ammonia is 16.84 pH. The temperature coefficient tCO is – 0.033 pH/°C.

Display Mnemonic AbF. Software selectable on or oFF.
Factory setting is on. With the oFF setting, calibration
is performed according to Section 5.3.2, without auto-
matic recognition and temperature compensation of
the buffers.
The automatic buffer calibration feature (on setting)
provides automatic recognition of up to three of the
buffers listed below (selectable in Section 5.3.1
). In
addition, each buffer selection incorporates a temperature curve from 0-50°C so that the user does not
need to determine the correct buffer pH which corresponds to the buffer temperature (for best accuracy
in extreme temperature environments).
The stored buffer-temperature curves were generated
from reference data according to NBS (National
Bureau of Standards - U.S.), DIN 19266 (Germany),
BSM (British Standards Method), and JIS 8802
(Japan) standards. The buffers are supplied by a wide
variety of vendors.
NOTE
If any buffers other than those listed here

SECTION 5.0
START-UP AND CALIBRATION
5.1 START-UP AND CALIBRATION. Calibration and
operation of the Model 1054B should begin only after
completion of configuration of the analyzer. The sensor must be wired to the Model 1054B for calibration.
5.2 TEMPERATURE CALIBRATION. For accurate
temperature correction, the temperature reading may
need adjusting. The following steps should be performed with the sensor in a grab sample or in the
process. For the best accuracy, the standardization
should be performed at or near the process temperature.
1. Observe the analyzer temperature reading by
pressing the TEMP key. Allow the reading to stabilize to insure that the sensor has acclimated to
the process temperature.
2. Compare the reading to a calibrated temperature
reading device. If the reading requires adjusting,
proceed to Step 3.
3. Press the TEMP key then the SELECT key to
correct the temperature display. The analyzer
will display AdJ briefly, then the Numeric Display
will show with digit flashing.
4. SCROLL (é) and SHIFT (ç) to key in the correct value and ENTER it into memory. Proceed to
Section 5.3.
5.3 BUFFER CALIBRATION (1054B pH only). The
two buffer calibration will calculate the slope (efficiency) of the pH sensor and standardize the reading on
the second buffer (computed slope limits: 47.3 to 59.9
mV/pH). The analyzer has been set at the factory for
automatic calibration. If the software setting has been
changed to disable this feature in Section 4.9 proceed
to Section 5.3.2. Otherwise, proceed to Section 5.3.1.
5.3.1 Automatic Calibration
1. Press the HOLD key twice to place the analyzer in
hold.
2. Obtain two buffer solutions with values at least
two pH units apart. Unopened buffers have a
shelf life of about a year and once opened should
generally not be reused because of possible contamination.
3. Shake the sensor down to remove entrapped air
bubbles from the glass electrode tip.
4. Place the sensing portion of the pH sensor into a
beaker containing the first buffer solution. Allow
the pH reading to stabilize. This may take several
minutes, as the pH sensor may need to cool down
to the buffer temperature. If you don't wait long
enough you may get a slope error.
5. Press the CAL key. Ab1 will flash briefly, followed
by a flashing pH buffer value at 25°C (If Ab2
appears, press the CAL key again for Ab1).
6. If the value displayed is not the value of your
buffer at 25°C (see Section 4.9) press the
SCROLL (é) key until your choice appears.
ENTER the value.
7. Remove the sensor from the buffer, then rinse and
dry it. Place it in the second buffer. Allow the pH
reading to stabilize. This may take several minutes, as the pH sensor may need to cool down to
the buffer temperature. If you don't wait long
enough you may get a slope error.
8. Press the CAL key again. Ab2 will display briefly,
followed by a flashing pH buffer value at 25°C. (If
Ab1 appears, press the CAL key again for Ab2).
9. If the value displayed is not the value of your
buffer @ 25°C, press the SCROLL (é) key until
your choice appears. ENTER the value.
10. Press the HOLD key twice again to remove the
analyzer from hold.
11. In the future the selected buffers will be recognized by the analyzer and can be used for either
Ab1 or Ab2.
12. For maximum accuracy, perform a process
standardization after a buffer calibration (see
Section 5.4). Also, you can track your electrode
slope value after a buffer calibration to see how
the electrode is aging (see Section 5.5).

are located on the label of most buffer bottles.
6. Press the CAL key once. bF1 will display briefly,
followed by the Numeric Display with digit flashing. If bF2 displays, press the CAL key again.
7. SCROLL (é) and SHIFT (ç) to key in the buffer
solution value, then ENTER it into memory.
8. Remove the sensor from the buffer, rinse and dry it.
9. Place the sensing portion of the pH sensor into a
beaker containing the second buffer solution.
10. Allow the pH reading to stabilize. See note in
step 5.
11. Press the CAL key once. bF2 will display briefly,
followed by the Numeric Display with digit flashing. If bF1 displays, press the CAL key again.
12. SCROLL (é) and SHIFT (ç) to key in the buffer
solution value, then ENTER it into memory.
13. Press the HOLD key twice to remove the analyzer from hold.
14. For maximum accuracy, perform a process standardization after a buffer calibration (see Section
5.4). Also, you can track your electrode slope
value after a buffer calibration to see how the
electrode is aging (see Section 5.5).
5.4 pH STANDARDIZATION (1054B pH only). For
maximum accuracy, the sensor should be standardized on-line or in a process grab sample after a buffer
calibration to account for the sensor junction potential. Sensor standardization will not calculate the sensor’s slope.
1. Take a grab sample which is as close to the sensor as possible. Write down the value the analyzer is reading at this time.
2. Using a calibrated pH instrument with automatic
temperature compensation, determine the pH of
the process or grab sample. The calibration is
best performed at the process temperature. Write
down this value. (If the sample pH is greater than
about 6.5 and the lab sample is run at a substantially different temperature than the process, see
Section 4.7).
3. Before entering the standardized value, compare
the value the analyzer is reading now to the value
in Step 1. Add this change to the reference value
obtained in Step 2. This accounts for the change
while the grab sample is being measured.
4. Press the pH key once, then press the SELECT
key. Std will show followed by the Numeric
Display with digit flashing.
5. SCROLL (é) and SHIFT (ç) to key in the corrected reference pH value determined in Step 3
then ENTER it into memory.
5.5 pH GLASS SLOPE. The slope/efficiency of the
glass electrode can be displayed or entered directly
(if known) without buffer calibrating (A new electrode
has a slope of about 59 mV/pH. As electrode ages
the slope will decrease to about 47-49 mV/pH).
1. Press the CAL key twice, then the SELECT key
once.
2. SCROLL (é) and SHIFT (ç) to key in the correct value then ENTER it into memory.
5.6 SENSOR MAINTENANCE. Before performing
buffer checks or maintenance of the sensor, the analyzer should be placed in hold. This will place the current output and relays in the state set in the default
setup (Section 4-8). Press the HOLD key twice. The
hold flag will show to indicate the hold condition.
Always calibrate after cleaning or repair of the pH
sensor. (Refer to Section 5.3.1 and Section 5.3.2.)
After installing the sensor back in the process, press
the HOLD key twice again to remove the analyzer
from hold.
NOTE
To clean the electrode, rinse with distilled
water or diluted acid/base, then gently dry
with a clean tissue. The electrode should
not be rubbed or abraded because this
increases the electrostatic forces and thus
the response time of the electrode, and it
also rapidly ages the delicate electrode
gel layer. If possible, increase the stirring
or flow velocity past the electrode rather
than rubbing or brushing it.
For any additional instructions, please
refer to the appropriate sensor instruction
manual.

5.7. STANDARD ORP SOLUTION (1054B ORP only).
Procedures are given below for making (2) types of
standard ORP solutions with known oxidation reduction potentials. Either one will be used to calibrate the
ORP system following the steps at the end of the section.
CAUTION
The following recipes contain chemical
components that require protective measures and precautions- Wear protective eye
gear and clothing while working with these
solutions.
A. QUINHYDRONE SOLUTION. Saturated quinhydrone is a commonly used ORP standard solution. It is
made by adding a few crystals of quinhydrone to
either pH 4 or pH 7 buffer. Quinhydrone is only slightly soluble, so a few crystals are all that are needed.
The resulting solution will be yellow-colored. The millivolt potentials, measured with a clean platinum electrode, should be within ± 20 millivolts of the values
shown. Solution temperature must be noted to assure
accurate interpretation of results. The ORP value of
saturated quinhydrone solution is not stable over long
periods of time; therefore, these solutions should be
made up fresh each time they are used.
B. FERRIC-FERROUS AMMONIUM SULFATE
SOLUTION. This standard ORP solution is not as easy
as the quinhydrone solution to prepare, but is much
more stable and will maintain its millivolt value for
approximately one year when stored in a glass container.
To prepare the solution, dissolve 39.2 grams of
reagent grade ferrous ammonium sulfate
[Fe (NH4)2(SO4)2•6H2O]
and 48.2 grams or reagent ferrous ammonium sulfate
[FeNH4(SO4)2•12H2O]
in approximately 700 milliliters of water (distilled water
is preferred, but tap water is acceptable). Slowly and
carefully add 56.2 milliliters of concentrated sulfuric
acid. Add sufficient water to bring the total solution
volume up to 1000 milliliters.
This solution (ferric-ferrous ammonium sulfate) will
produce a nominal ORP of 476 ± 20 mV at 25°C when
used with a saturated KCl/AgCl reference electrode
and a platinum measuring electrode. Some variance
in mV values is to be expected due to the large liquid
reference junction potentials which can arise when
measuring this strongly acidic (and concentrated)
solution. However, if the measuring electrodes are
kept clean calibrations can be achieved.

7.1 THEORY OF OPERATION (pH). This section is a
general description of how the Model 1054B pH operates. This section is for those users who desire a
greater understanding of the analyzer's operation.
The measurement of the process’ pH is accomplished by the use of two electrodes within the sensor. The glass electrode is pH sensitive and
generates a high impedance millivolt potential directly
proportional to the process pH. The reference electrode is a second half cell that completes the circuit
via a liquid junction. The high impedance signal is
preamplified at the sensor to allow a stable noise-free
signal that can be transmitted up to 1,000 feet.
The Model 1054B pH also measures the process temperature via a platinum 100 ohm RTD imbedded in
the sensor. Advanced circuitry is used to eliminate
errors due to changes in cable resistance. The analyzer uses this temperature measurement to compensate for changes in the sensor millivolt output caused
by temperature change.
7.2 THEORY OF OPERATION (ORP). This section is
a general description of how the 1054B ORP operates. The selected sensor generates a voltage
dependent on the oxidation reduction potential (ORP)
measured in the process. This voltage signal is fed
into a high-impedance amplifier (preamp) prior to
transmission to the Model 1054A ORP. The high
impedance and low voltage of the sensor make a preamplifier necessary for a reliable ORP signal to reach
the transmitter.
The analog signal from the preamp is digitized by the
signal conditioning circuit, becoming a digital signal
(proportional to the ORP) that can be read by the
CPU. This digital signal is then used to calculate an
ORP value.
The CPU also contains an on board electrically erasable and programmable read-only memory
(EEPROM) which maintains memory during power
outages. The CPU is supported by read-only memory
(ROM) containing the operating instructions for the
CPU.
The CPU controls the operation of the liquid crystal
display, Alarm 1, Alarm 2 and also creates a pulse
width modulated (PWM) signal. The PWM signal is
converted by the isolated output circuit (located on
the power board) to a selectable current output (0 to
20mA or 4 to 20mA).
The keyboard is a matrix of on/off switch positions
that the CPU scans periodically to determine if a
button is depressed. The CPU reacts when a key is
depressed to display a different parameter or to modify its function in some manner. Even though the ORP
measurement is not temperature sensitive, process
temperature is accurately measured at the ORP sensor through the use of a PT-100 RTD and is displayed
by the 1054A ORP over the range of -15 to135°C. For
a more accurate temperature reading the analyzer
temperature indication may be standardized to the
process temperature by pressing the TEMP key and
adjusting the indicated value.

DIAGNOSTICS AND TROUBLESHOOTING
SECTION 8.0
DIAGNOSTICS AND TROUBLESHOOTING
8.1 DIAGNOSTICS. The Model 1054B has a diag-
nostic feature which automatically searches for fault
conditions that would cause an error in the measured
pH/ORP value. If such a condition occurs, the current
output and relays will act as configured in Section 4.8
and the fault flag and display will flash. A fault code
mnemonic will display at frequent intervals. If more
than one fault condition exists, the display will
sequence the faults at one second intervals. This will
continue until the cause of the fault has been corrected. Display of fault mnemonics is suppressed when in
Set Mode. Selecting the SHO item will display a history
of the two most recent fault conditions unless SHO was
cleared. Refer to Section 4.8C.
NOTE
If the analyzer is in hold and a fault
occurs, the mnemonic HLd will display
during the fault sequence.
8.1.1 Fault Mnemonics. Table 8-1 lists the fault
mnemonics and describes the meaning of each.
8.1.2 Temperature Compensation. T
able 8-2 is a
ready reference of RTD resistance values at various
temperatures. These are used for test and evaluation
of the sensor.
NOTE
Ohmic values are read across the RTD
element and are based on the manufacturer’s stated values (±1%). Allow
enough time for the RTD element to
stabilize to the surrounding temperature.

DIAGNOSTICS AND TROUBLESHOOTING
8.2 TROUBLESHOOTING. The Model 1054B
Analyzer is designed with state-of-the-art microprocessor circuitry, making troubleshooting simple
and direct. Subassembly replacement, i.e. printed
circuit board replacement, is all that is usually
required.
8.2.1 Installation Failure. If failure does occur, complete the following steps:
1. Check for a fault flag. If a fault condition exists,
refer to Table 8-1 for the fault mnemonic explana-
tion.
2. Check wiring connections for proper installation.
3. Refer to Troubleshooting Table 8-3 (pH) or
Table 8-4 (ORP). The table is arranged with the
most common problems listed first.
8.2.2 LCD/LED Display Test. Display Mnemonic dtS.
Selecting this option will activate all the display segments. This item is used if a faulty display is suspected. Refer to Figure 3-1.
1. Enter Set Mode by pressing ACCESS key twice.
2. SCROLL (é) until dtS appears on the display.
3. SELECT.
8.2.3 Software Version. Display Mnemonic UEr.
Selection of this item will display the software revision
level of the CPU. This number may be requested by
factory service personnel if troubleshooting is
required.
1. Enter Set Mode by pressing ACCESS key twice.
2. SCROLL (é) until UEr appears on the display.
3. SELECT. (i.e., 2.0.6 displayed.)
8.2.4 Sensor Troubleshooting. In addition to the
fault mnemonics that relate to a possible sensor
problem (Table 8-1 and Table 8-3), the 1054B pH can
display the input in millivolts generated from the sensor. See Table 8-5 for how the millivolt input relates to
pH. If the analyzer values do not agree within about
40 to 60 mV of those in the table, the analyzer has
been incorrectly standardized for pH, the reference
may be significantly poisoned, or some other significant problem exists. To read the millivolt input, go to
Section 8.2.5.
For an additional diagnostics tool you can look at the
rES impedance value as described in Section 4.6.
8.2.5 Electrode Input (1054B pH). Display Mnemonic
Ein. When selected, the analyzer displays the millivolt
input from the sensor. The displayed value is not temperature corrected.
1. Press the ACCESS key twice. SEt will briefly dis-
play followed by Ein. Not required if already in
set menu.
2. SELECT this item to read the mV input.
3. Press the PV key to return to normal operation.
8.2.6 CPU Board Replacement. If there is a problem
with the CPU board resulting in its replacement, specific procedures (included with the order) for calibrating the new board must be followed exactly or the
microprocessor will be improperly programmed.
Should this occur, it will be necessary to return the
analyzer to the factory for reprogramming.
8.2.7 Power Board Replacement. If it becomes nec-
essary to replace the power board, the CPU board
will need to be recalibrated following specific procedures that are included with the power board. Failure
to follow these procedures exactly will cause the
microprocessor to be improperly programmed and
require the return of the analyzer to the factory for
reprogramming.
8.3 INSTRUMENT MAINTENANCE. To maintain the
appearance and extend the life of the enclosure, it
should be cleaned on a regular basis using a mild
soap and water solution followed by a clean water
rinse.
