OPERATING INSTRUCTIONS

DEFAULT SETTINGS:

• Temperature Units: °C (Temperature is displayed in Degrees Celsius)

• Solution Mode: Conductivity – KCl

MEASUREMENT SETUP: Before you take a reading, make sure the PS9 is

clean, calibrated, and if measuring COND or TDS, that the desired
solution mode has been selected (See Section II of Operating
Instructions, below). The sample solution must also be within the
specified range.

I. MEASUREMENT

1. Rinse and empty the appropriate sensor (conductivity or pH / ORP) 3 times
with sample to be measured.

2. Fill with test sample.

3. Press appropriate Measurement Key:

COND to measure CONDUCTIVITY
0-9999 MICROSIEMENS (µS/cm), 10-200 (mS)/cm

TDS: Measures TOTAL DISSOLVED SOLIDS
0-9999 parts per million (ppm), 10-200 (ppt)

MIN / SALT: Same as TDS but displays in
0 - 200 parts per thousand (ppt). displays as PPT of NaCl

ORP: Measures Oxidation Reduction Potential (REDOX) ± 999 mV

pH: Measures 0-14 pH

Press one of these to preform an Alkalinity or Hardness
measurement.

Press to calculate LSI. Uses stored or hypothetical Alkalinity and
Hardness data.

• For complete instructions on performing these measurements,
download the full PoolPro PS9 Operation Manual and watch our
YouTube videos (Search for: Ultrameter III 9P and 9PTK).

NOTES:

• When finished making Conductivity, TDS, MIN/SALT ALK or HARD
measurements, rinse the cell cup with clean water (preferably DI, RO, or
distilled).

• When finished measuring pH, ORP or FCE, rinse sensor well with clean
water (preferably DI, RO, or Distilled), refill it with Myron L Storage Solution
then reinstall protective cap.

II. Solution Mode Selection

1. Press , or , to select which parameter is having its solution

type changed.

2. Press and hold about 3 seconds or until "SEL" appears on the
display.

3. Use the or key to select type of solution desired. The

possible solution types are KCI, NaCl or 442™(a Myron L® Company
natural water).

4. Press to accept new solution type.

2. Refill cell cup with fresh, standard solution.

3. Press , or , then press , "CAL" will appear.

4. Press or until display agrees with standard solution.

5. Press to accept value.

NOTE: A deviation of more than 10% from standard solution value will

produce a "FAC" on the display. Press to accept factory calibration,
or clean the cell and recalibrate.

full PoolPro PS9 Operation Manual.

III. pH/ CALIBRATION

1. Rinse sensor well 3 times with 7.0 buffer solution.

2. Refill sensor well with 7.0 buffer solution.

3. Press , then , "CAL", "7" and "BUFFER" will appear on the

display.

4. Press or until display agrees with buffer value.

5. Press once to accept the value.

6. Rinse 3 times with either ACID (Acd) (pH 1- 6) or BASE (bAS) (pH 8-14)

buffer solution.

7. Refill and repeat steps 4 & 5.

8. Rinse 3 times with opposite buffer solution, refill and repeat steps

4 & 5 or press to exit.

9. When calibration is complete, refill sensor well with Myron L Storage
Solution or a high KCI solution and reinstall cap.

IV. ORP/ FCE CALIBRATION

• ORP electrodes rarely give false readings without problems in the reference

electrode.

• For this reason, and because calibration solutions for ORP are highly

reactive and potentially hazardous, your PoolPro has an electronic ORP
calibration.

• This causes the zero point on the reference electrode to be set whenever

pH 7 calibration is done.

MAINTENANCE

I. BATTERY REPLACEMENT (LOBATT)

1. Clean and dry Instrument THOROUGHLY.

WARNING: ONLY open PS9 in a clean, dry environment!

2. Remove the four (4) bottom screws.

3. Open instrument CAREFULLY.

4. Carefully detach battery from circuit board.

5. Replace with 9-volt alkaline battery.

6. Replace bottom, ensuring the sealing gasket is installed in the groove of

the top half of case.

7. Re-install the 4 screws, tightening them evenly and securely.

II. CAUTIONS

• Solutions in excess of 71°C/160°F should not be placed in the cell cup area;

this may cause damage.

• The pH sensor may fracture if the PS9 temperature is allowed to go below

0°C/32°F.

• The Conductivity cell cup should be kept as clean as possible. Flushing with

clean water following use will prevent buildup on electrodes. If very dirty
samples (particularly scaling types) are allowed to dry in the cell cup, a film
will form reducing accuracy.

• The pH sensor in your PS9 should not be allowed to dry out.

• Whenever the pH sensor is not in use make sure it is filled with

Myron L® Company Storage Solution and that the protective cap is in place.

III. CLEANING SENSORS

A. Conductivity, TDS, MIN/SALT, ALK, HARD, and LSI

• When there are visible films of oil, dirt, or scale in the cell cup or on the
electrodes or if readings are not as expected, use isopropyl alcohol or a
foaming non-abrasive household cleaner.

• Rinse out the cleaner, and your PS9 is ready for accurate calibration then
measurements.

B. pH: If the pH sensor dries out or becomes dirty, it may be cleaned and/or

reconditioned. For instructions on preforming these operations, download
the full PS9 Operation Manual from the Myron L® Company website.

IV. pH Sensor Replacement

Order model RPR. Be sure to include the model and serial number of your
instrument to ensure receipt of the proper type. NOTE: Complete installation
instructions are provided with each replacement sensor.
