Set the sample target pH (analyzer without cationic pump)
Note: This task only applies to analyzers without the optional cationic pump. Refer to Product overview in the
installation manual to identify the cationic pump.
Before the measurement, the analyzer increases the pH of the sample to between 10.7 and 11.4 with
a conditioning solution to prevent ion interference. The analyzer automatically adjusts the quantity of
the conditioning solution that is added to the sample to keep the sample pH constant.
Set the target sample pH as follows:

TARGET.
2. Set the target pH (10.7 to 11.4). The recommended setting is pH 11.2 (default).
Set the sample target pH (analyzer with cationic pump)
Note: This task only applies to analyzers with the optional cationic pump. Refer to Product overview in the
installation manual to identify the cationic pump.
Before the measurement, the analyzer increases the pH of the sample to between 11.2 and 11.4 with
a conditioning solution to prevent ion interference. Set the ratio of the conditioning solution, which is
added as a gas, and the sample for each channel (Tgas/Twater). The Tgas/Twater ratio is based on
the pH of the unconditioned sample.
Item to collect: Calibrated pH sensor to put into the middle chamber of the measurement cell (or a
pH test strip)
Set the Tgas/Twater ratio for each channel as follows:
1. Identify the pH of the sample for each channel before it goes into the analyzer.
2. Push menu, then select SETUP SYSTEM > CONFIGURE ANALYZER > MEASUREMENT >
TGAS/TWATER.
3. Select the channels one at a time (e.g., TGAS/TWATER1 = Channel 1). Enter the applicable
Tgas/Twater value from Table 3 (default: 20%).
4. Push home.
5. Let the analyzer operate for 1 hour to stabilize.
6. Identify if the conditioned sample pH is between 11.2 and 11.4 as follows:
a. Remove the sodium electrode from the middle chamber of the measurement cell. Put the
sodium electrode in deionized water to keep the electrode wet.
b. Put a calibrated pH sensor in the middle chamber of the measurement cell.
English

c. For each channel, record the pH of the sample while the measurement status bar shows on
the display.
d. If the pH of a sample(s) is not between 11.2 and 11.4, set the Tgas/Twater setting for the
channel to a higher (or lower) percentage as necessary. Then, after 1 hour of operation, do
step c again.
e. If the pH of a sample(s) is not between 11.2 and 11.4 when the Tgas/Twater is set to the
maximum value, refer to "PH TOO LOW" in the troubleshooting table of the maintenance
manual to identify the problem.
7. When the conditioned sample pH of each channel is between 11.2 and 11.4, install the sodium
electrode back in the middle chamber of the measurement cell.

OptionDescription
SEARCH
STABILITY
Between channel measurements, the analyzer rinses the measurement cell with sample
from the next channel to be measured for a set time interval (or until the measurement is
stable).
NO (default)—Sets search stability to off. The analyzer rinses the measurement cell for a set
time interval. As a result, the measurement logging interval is constant.
When SEARCH STABILITY is set to NO, the settings to configure are CYCLE TIME and ON
LINE MEASURE time.
Measurement logging interval = CYCLE TIME
CYCLE TIME = ON LINE MEASURE time + Rinsing time (set value)
YES—Sets search stability to on. The analyzer rinses the measurement cell only until the
measurement is stable, which minimizes the rinsing time. As a result, the measurement
logging interval is variable.
When SEARCH STABILITY is set to YES, the settings to configure are MAX CYCLE TIME
(maximum measurement logging interval) and ON LINE MEASURE time.
Measurement logging interval = ON LINE MEASURE time + Rinsing time (variable)

Set the reactivation schedule
With time, the sensitivity of the sodium electrode decreases because of the very low levels of sodium
in the sample water. Auto reactivation adds a small quantity of reactivation solution to the
measurement cell at regular intervals (e.g., 24 hours) to increase the sensitivity of the sodium
electrode. Auto reactivation increases the accuracy of the analyzer measurements.

Reset the overfeed timer for relays
The overfeed timer setting for the relays prevents a condition that keeps the measurement value
higher than the setpoint or deadband setting (e.g., damaged electrode or a process upset) from
keeping a relay switched on continuously. The overfeed timer limits how long the relays and their
connected control element stay on independent of the conditions.
When the select time interval for the overfeed timer expires, the relay status flashes on the top-right
corner of the measurement screen until the overfeed timer is reset. Push diag, then select
OVERFEED RESET to reset the overfeed timer.

Note: Only do this task if the analyzer has a calibration bottle. Refer to Product overview in the installation manual
to identify the calibration bottle.
The water level of the overflow vessel is important for accurate auto calibration. Before an auto
calibration is done, adjust the water level so that the water is between the top mark (+) and the
bottom mark (–). Make sure that the analyzer is level from front to back and side to side.
1. Wait until the overflow vessel is full of water.
2. If the water is higher than the top mark (+) or lower than the bottom mark (–) on the overflow
vessel, do the steps that follow:

Note: Do not use a standard solution that is less than 100 ppb because it can quickly

Starts a 2-point manual calibration. When prompted, add 200 mL of each calibration
standard to the overflow vessel. The recommended standards are 100 ppb and 1000 ppb.
Important: The difference in temperature of the two calibration standards must not be more
than ± 5 °C (± 9 °F). The second calibration standard must have a sodium concentration
that is 5 to 10 times more than the first calibration standard (e.g., 100 ppb and 1000 ppb). A
large difference between the sodium concentration of the calibration standards is necessary
to get an accurate calibration.
Note: Do not use a standard solution that is less than 100 ppb because it can quickly
become contaminated, which changes the concentration.
Prepare calibration standards
To prepare a 100-ppb Na standard and a 1000-ppb Na standard to do a manual calibration, do the
steps that follow. All volumes and quantities used to prepare the calibration standard must be
precise.
Items supplied by the user:
• Volumetric flask (4x), 500 mL, Class A
• NaCl, 1.272 g
• Ultra pure water, 500 mL
• 1–10 mL TenSette pipet and tips
1. Prepare 500 mL of 1-g/L Na calibration standard as follows:
a. Rinse the volumetric flask with ultra pure water three times.
b. Add 1.272 g NaCl to the volumetric flask.
c. Add 100 mL of ultra pure water to the volumetric flask.
d. Shake the volumetric flask until the powder is fully dissolved.
e. Add ultra pure water to the 500-mL mark.
f. Shake the volumetric flask to fully mix the solution.
2. Prepare 500 mL of 100-ppm Na calibration standard as follows:
a. Rinse the other volumetric flask with ultra pure water three times.
b. Use a pipet to add 5 mL of the 1-g/L Na standard to the volumetric flask. Put the pipet in the
flask to add the solution.
c. Add ultra pure water to the 500-mL mark.
d. Shake the volumetric flask to fully mix the solution.
3. Prepare 500 mL of 100-ppb Na calibration standard as follows:
a. Rinse the other volumetric flask with ultra pure water three times.
b. Use a pipet to add 5 mL of the 100-ppm Na standard to the volumetric flask. Put the pipet in
the flask to add the solution.
c. Add ultra pure water to the 500-mL mark.
d. Shake the volumetric flask to fully mix the solution.

4. Prepare 500 mL of 1000-ppb Na calibration standard as follows:
a. Rinse the other volumetric flask with ultra pure water three times.
b. Use a pipet to add 50 mL of the 100-ppm Na standard to the volumetric flask. Put the pipet in
the flask to add the solution.
c. Add ultra pure water to the 500-mL mark.
d. Shake the volumetric flask to fully mix the solution.
5. Keep the solutions that are not used in a clean plastic bottle. Rinse the bottle with ultra-pure

which changes the concentration.
Important: The temperature of the calibration standard must not be more than ± 5 °C (9 °F)
different than the calibration standard that was used to calibrate the analyzer.
5. When the calibration verification is completed, do a calibration immediately if "FAIL" shows. If
"PASS" shows, no action is necessary.
Do a temperature calibration
Make sure that the temperature reading is accurate as necessary.
1. Remove the sodium electrode from the middle chamber of the measurement cell.
