SECTION 1.0

DESCRIPTION AND SPECIFICATIONS

• pH ELECTRODE DIAGNOSTICS warn user of the need for calibration or electrode replace-

ment.

• AUTOMATIC BUFFER RECOGNITION with stored buffer-temperature curves

(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 tempera-

ture (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.

CONFIGURATION

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 on page 20 (or, in the case of ORP, the worksheet on page 22) 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 (page 20 - pH, page 22

- ORP). This will reduce the chance of accidentally omitting a needed variable.

MODEL 1054B pH/ORP SECTION 4.0

CONFIGURATION

4.6 pH ELECTRODE DIAGNOSTICS (1054B pH only). Display Mnemonic InP. Under this item are func-

tions associated with glass electrode diagnostics. These diagnostics are possible through a continuous, temperature compensated measurement of the sensor impedance (resistance), rES, made from the preamp. A soft-

ware selectable on setting will activate these diagnostics. If oFF is the setting (factory setting) these diagnostics will all be disabled.

A new electrode has an impedance of approximately 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 special 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.

START-UP AND CALIBRATION

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).

1. Press the HOLD key twice to place the analyzer in hold.

2. Obtain two pH buffer solutions with values at least two pH units apart. Unopened buffers have a shelf life of about a year and once opened they should generally not be reused because of possible contamination.

3. Shake the sensor down to remove entrapped air bubbles from the pH glass electrode tip.

4. Place the sensing portion of the pH sensor into a beaker containing the first buffer solution.

5. Allow the pH reading to stabilize. 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. Then note the temperature and find the buffer value at that temperature. Buffer values at various temperatures 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

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 Sections 5.1.2 and 5.1.3.) 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.

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.

5.8. ORP STANDARDIZATION (1054B ORP only).

For maximum accuracy, the sensor should be standardized in the ORP standard process or process grab sample.

Step 1: Ensure that the Model 1054B is in hold (Hold flag showing). If not, Press the HOLD key twice.

Step 2: Using a ORP standard, determine the ORP of the solution.

Step 3: Ensure that the sensor’s measurement portion is in the process or grab sample.

Step 4: Allow the reading to stabilize.

Step 5: Press the PV or CAL key once, then Press the SELECT key. Std will show followed by the Numeric

Display with digit flashing. Step 6: SCROLL (é) and SHIFT (ç) to display the proper ORP value then ENTER it into memory.

Step 7: Press the HOLD key twice to remove the Model 1054B from hold. The 1054B ORP is now ready for operation.

5.9. SENSOR MAINTENANCE. Before preforming maintenance or repair of the sensor, the Model 1054B should be placed in hold. This will place the current output and relays in the state set in the default setup. Press the HOLD key twice. The hold flag will show to indicate the hold condition. Always calibrate (Section

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

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. Table 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 explanation.

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 (Tables 8-1 and 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 display 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.
