4 Installaon
4.1 Main Module Baery Installaon
The main module of the SP-710B is powered by four AA alkaline baeries. Typical baery life is 10,000 mea-
surements or 6 months. When the baery capacity is crically low, the SP-710B displays a ”LOW BATTERY”
warning for ve seconds and then automacally turns o.
The SP-710B does not turn itself on automacally aer the new baery installaon. To turn on the SP-
710B aer new baery installaon, press the OK key momentarily and release.
The SP-710B has a calendar mer. To prevent the calendar from being reset to the default date and me
(01/01/1970, 00:00:00), install the four new baeries within four minutes aer the old baeries are re-
moved from the baery compartment. The SP-710B date and me is synchronized automacally when
connected with uPyxis® Mobile or Desktop App.
The SP-710B baery compartment, shown in Figure 1, is on the back side of the instrument. Baeries
are held in place by a cover secured with two Phillips-head screws.
SP-710B User Manual [email protected] | [phone]

Figure 1. The SP-710B baery compartment
Use the following procedure to install new baeries:
1. Remove the baery compartment cover by loosening the two screws.
2. Remove the old baeries and dispose of them properly.
3. Following the posive and negave terminal signs in the compartment boom, snap four new AA
alkaline baeries rmly into the baery holder.
4. Replace the baery compartment cover and ensure that the sealing O-ring is lying at on the baery
holder.
5. Fasten the two screws.
*NOTE*Failure to properly seat the O-ring may result in water damage to the SP-710B.
4.2 pH/ORP Module Baery Installaon
The new pH/ORP module has a lithium thionyl chloride baery (3.7V-ER14250) installed. When the bat-
tery capacity is crically low and the main module displays a LOW BATTERY warning, replace the ER14250
baery. Use the following procedure to install a new baery:
1. Unsnap the pH/ORP module from the top of the main module.
2. Remove the baery compartment cover by using a coin or at-head screwdriver to turn the cover
counterclockwise.
3. Remove the old baery and dispose of it properly.
4. Following the orientaon of the baery as shown in Figure 2, put a new ER14250 baery into the
compartment.
5. Fasten the compartment cover by turning it clockwise.
6. Snap the pH/ORP module back atop the main module.

5.1 pH/ORP Cell Dual-Funcon Seal
The SP-710B pH/ORP rubber seal serves two purposes:
1. The seal contains a magnet which when opened to ush posion will power on the pH/ORP module.
2. When the SP-710B is in storage, the seal maintains a moist environment for the electrodes.
For vigorous eld use, it is recommended to ulize a rubber-band to secure the pH/ORP Cell Dual-Funcon
Seal to prevent loss of pH/ORP Storage Soluon. The sponge soaked with the pH/ORP Storage Soluon in
the pH/ORP Cell Dual-Funcon Seal helps prolong the life of the pH/ORP module. It may be discarded if
desired, but pH/ORP Storage Soluon must be maintained in the unit cell at all mes during non-use. Please
ll the pH/ORP cell with 1 mL of Pyxis pH/ORP Storage Soluon (P/N: 63900) at all mes when not using
the pH/ORP cell.
Figure 4. pH/ORP Cell Dual-Funcon Seal in the open posion
5.2 Control Keys
The SP-710B has three control keys, as shown in Figure 3. The le ( ), right ( ), and ok ( ) keys
are used to launch acons indicated on the LCD display directly above the keys. The labels above the keys
indicate the funcon associated with each key and funcons can be changed in dierent operaon modes.
*NOTE*The LCD display is not a touch-enabled device.
5.3 Main Module On/O
To turn on the SP-710B: Press momentarily and release.
To turn o the SP-710B: Press and hold for about three seconds. Release when the LCD display
turns o. The SP-710B turns itself o aer 30 seconds without user interacon detected. This is done to
conserve baery life.
*NOTE*This auto-me o seng may be customized by the user as desired through the
uPyxis® Mobile or Desktop App.
5.4 pH/ORP Module On/O
The module is turned on by rotang the pH/ORP cell seal to touch the front face of the module as seen in
Figure 5. A sealed magnet within the rubber seal will trigger the module power circuit. The pH/ORP module
SP-710B User Manual [email protected] | [phone]

will turn itself o when either commanded by the main module or automacally based on the default or
customized idle me limit seng. The purpose for this design is to extend baery life.
If pH/ORP measurement is not needed, the module does not need to be turned on.
Figure 5.
6 Measurement
6.1 PTSA and Conducvity Measurement
6.1.1 Measurement Procedure
When powered on, the SP-710B will default to the PTSA and conducvity measurement mode. A water
sample should be transferred to the main module sample cell using a disposable pipee, or the cell can be
lled slowly from a sample bole.
*NOTE*Special care should be taken when pouring the sample into the cell to avoid air
bubble entrainment, which can interfere with reading accuracy.
Before beginning a measurement, use the sample water to rinse the main module cell at least three mes.
Allow 5–10 seconds for the SP-710B to stabilize. The values will be displayed in white with a blue background
if a stable value is reached (Figure 6). For a sample with conducvity in the range of 100 to 6000 µS/cm,
the measured value should be stabilized in the range of 98–102 to 5940–6060 µS/cm, respecvely. For a
sample containing 100 ppb PTSA, the measured PTSA should be stabilized within the range of 98–102 ppb.
*NOTE*The me required to reach a stable reading may be slightly longer if the water
sample temperature is signicantly dierent than the environmental temperature at which
the SP-710B had been equilibrated (stored).
SP-710B User Manual [email protected] | [phone]

Figure 6.
6.1.2 Temperature Compensaon
The displayed conducvity value is automacally compensated to the nominal value at the reference tem-
perature 25 °C using the sample temperature measured. The commonly used linear correcon equaon is
used:
Conductivity at 25 °C=Conductivity at Tmeasured
1+0.02(Tmeasured –25) (1)
where Tmeasured is the sample temperature in °C.
6.1.3 High Color and Turbidity Warning
The SP-710B has extra channels to measure sample turbidity and color to automacally compensate sam-
ple color and turbidity interference. If sample turbidity and color values determined are too high, a PTSA
measurement warning will be displayed. In such a case, the user should lter the sample for PTSA mea-
surement.
6.2 Fluorescein Measurement
Follow the steps below to measure Fluorescein:
1. Rinse the main module sample cell three mes with the sample. Fill the sample cell with the sample.
2. Power on the SP-710B by pressing . Allow 5–10 seconds for the SP-710B to stabilize.
3. Press Measure ( ) as needed to highlight Fluorescein in the selecon menu.
4. Press to launch the FLUORESCEIN MEASUREMENT screen (Figure 7).
SP-710B User Manual [email protected] | [phone]

Figure 7.
6.3 Temperature Measurement
The SP-710B has two planum RTDs located in the main module sample cell and the pH/ORP sample cell.
The temperature sensors are individually calibrated in the factory and do not need to be calibrated during
use. The temperature values measured are used in the conducvity temperature compensaon and in
converng the measured cell potenal to the pH value at the sample temperature.
6.4 pH/ORP Measurement
6.4.1 Measurement Procedure
Follow the steps below to measure pH and ORP:
1. Rotate the pH/ORP cell seal to touch the front face of the module as seen in Figure 5. This is to power
on the module. The indicator light of the module will be green and ashing when powered on. Aer
the module is turned on, the seal can be posioned anywhere desired.
*NOTE*If the module baery capacity is low, the indicator light will ash red .
2. Press Measure ( ) as needed to highlight pH/ORP in the selecon menu.
3. Press to launch the pH/ORP MEASUREMENT screen.
4. The main module of the SP-710B will automacally connect aer the pH/ORP module has been pow-
ered up.
5. Rinse the pH/ORP sample cell three mes with the sample to be tested. Fill the sample cell with the
sample.
6. The pH and ORP values will be updated every two seconds on the SP-710B main module display. The
values will be displayed in white with a blue background once a stable value is reached (Figure 8).
*NOTE*If the pH/ORP module powers o or was not powered on to begin with (see
step 1) an instrucon message will be promoted on the screen showing how to turn
on the pH/ORP module (Figure 9).
SP-710B User Manual [email protected] | [phone]

Figure 8. Figure 9.
6.4.2 Erroneous Values
An erroneous pH value could be obtained if the module has been stored dry without the protecon of
pH/ORP Storage Soluon for a long period of me. In this case, please ll the module cell with pH/ORP
Storage Soluon to wet the electrode and allow it to soak for 30 minutes before use. If the pH/ORP Storage
Soluon is not available, please use the sample water to hydrate the electrode for at least 30 minutes.
6.4.3 pH Measurement Principle
The SP-710B pH/ORP module uses the standard electrochemical cell for the pH measurement. The cell con-
sists of a glass electrode and an Ag/AgCl reference electrode. Potassium chloride (KCl) electrolyte lling gel
is sealed in the Ag/AgCl electrode. The amount of reference electrolyte in the pH/ORP module is signi-
cantly larger than that used in a common laboratory pH electrode. This reduces the chance of the lling
soluon being diluted or contaminated and increases the electrode life.
The pH value is calculated from the measured cell potenal (EMF in mV):
pH =EMF
S(T) + pHo
(2)
S(T) = 0.1986(T+ 273.15) (3)
S(T)in the above equaon is the calibraon slope, where Tis temperature in degrees Celsius. S(T)has
a theorecal value of 59.17 mV at 25 °C. pHois the calibraon intercept. The calibraon slope, S(T), at
the nominal temperature 25 °C and the intercept, pHo, are determined in the two-point or three-point
calibraon procedure. pHois determined as well in the singe-point pH 7.00 calibraon. The temperature
value measured by the pH/ORP module is used in the above equaon to calculate the pH value at the sample
temperature.
*NOTE*The temperature compensaon involved in the pH value calculaon is quite dif-
ferent from that in the conducvity measurement. The temperature-compensated conduc-
vity value is a would-be value at the reference temperature 25 °C, while the pH value
displayed by the SP-710B is the true pH value at the sample temperature.
SP-710B User Manual [email protected] | [phone]

6.4.4 ORP Measurement Principle
The SP-710B measures the sample ORP with the planum electrode and the Ag/AgCl reference electrode
in the pH/ORP cell. The pH measurement and the ORP measurement share the same reference electrode.
Reporng an ORP value without specifying the reference scale has no meaning. The value displayed by
the SP-710B depends on the ORP value of the ORP standard used in the calibraon. If the ORP value of the
standard is referenced to the Standard Hydrogen Electrode (SHE), the ORP value reported by the SP-710B
is SHE-based, i.e., in the unit of Eh. If the ORP value of the standard is referenced to the Ag/AgCl (3M KCl)
electrode, the ORP value reported by the SP-710B is referenced to the same, commonly noted as (Ag/AgCl,
3M KCl).
The ORP electrode is calibrated using the Zobell’s standard using the value of 221 mV at 25 °C before ship-
ping. The default ORP scale of the SP-710B before a user calibraon is the Ag/AgCl (3M KCl). If the SP-710B
is exposed to an extremely high (> +600 mV) or extremely low (< -200 mV) ORP sample, rinsing the pH/ORP
cell excessively when switching to measure a lower or higher redox buer capacity sample is necessary.
The dissolved oxygen in the sample can contribute to the ORP value measured. To measure a sample that
has not be equilibrated with the ambient air, a slow and small upward driing to more posive ORP value
is normal. For a typical cooling water sample treated with oxidizing biocides, a ±20 mV accuracy and ±10
mV precision can be expected.

7 Calibraon
7.1 PTSA Calibraon (Two-Point with Zero)
1. Rinse the main module sample cell three mes with DI water. Fill the sample cell with DI water.
*NOTE*In emergency, “non-PTSA” water, such as city water, may be used, but re-
calibrate using DI water for the zero step as soon as it is available.
2. Power on the SP-710B by pressing . Allow 5–10 seconds for the SP-710B to stabilize.
3. The unit is acvely reading and displaying both PTSA and Conducvity. The values will be very low if
DI water is used; conducvity value is not crical but PTSA value should be near zero. A low non-zero
value (e.g. 0.2 or 0.4, etc.) is not problemac.
4. Press Calib ( ) as needed to highlight PTSA in the selecon menu.
5. Press to launch the PTSA CALIBRATION screen (Figure 10).
6. Press Zero ( ) to start the zero (blank) calibraon.

7.2 Combined PTSA and Conducvity Calibraon
The following steps will calibrate both conducvity at 1000 µS/cm and PTSA at 100 ppb using Pyxis 100 ppb
PTSA + 1000 µS/cm (KCl) Combined Standard (P/N: 21004):
1. Rinse the main module sample cell three mes with the Combined Standard. Fill the sample cell with
the Combined Standard.
2. Power on the SP-710B by pressing . Allow 5–10 seconds for the SP-710B to stabilize.
3. Press Calib ( ) as needed to highlight Cond in the selecon menu.
