NOTES:
•
When finished making Conductivity, Resistivity, TDS, Alkalinity or Hardness
measurements, rinse the cell cup with clean water (preferably DI, RO, or
distilled).
•
When finished measuring pH, ORP or FC
E
, rinse sensor well with clean water
(preferably DI, RO, or Distilled), refill it with Myron L
®
pH/ORP Sensor Storage
Solution then reinstall the 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 Natural Water™ Standard.
4. Press to accept new solution type.
NOTE: The solution mode selection determines the salt solution characteristic
used to model temperature compensation for conductivity, resistivity and TDS.

ORP calibration is electronic and based on pH Cal Results
Resistivity is the reciprocal of Conductivity. To calibrate resistivity, calibrate conductivity
for the solution type you wish to measure
I. CONDUCTIVITY OR TDS CALIBRATION
1. Rinse cell cup 3 times with proper standard solution.
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.
II. ALKALINITY and HARDNESS CALIBRATION
•
For complete instructions on performing these calibrations, download the full
Ultrameter III 9P Operation Manual.
III. pH CALIBRATION
1. Rinse sensor well and cell cup 3 times with 7.0 buffer solution.
2. Refill sensor well and cell cup 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 pH 4.0 or pH 10.0 buffer solution.
7. Refill and repeat steps 4 & 5.
8. Rinse 3 times with opposite buffer solution, refill and repeat steps 4 & 5 for a
3-point calibration, or press to exit.
9. When calibration is complete, rinse the sensor well then fill it with Myron L
®
pH/ORP Sensor Storage Solution and reinstall the protective cap.
IV. ORP/ FC
E
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 Ultrameter III 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 the instrument THOROUGHLY.
WARNING:
ONLY
open the 9P in a clean and dry environment!
2.
Remove the four (4) bottom screws.
3.
Open the instrument CAREFULLY.
4.
Carefully detach the battery from the circuit board.
5.
Replace with a new 9-volt alkaline battery.
6.
Replace bottom, ensuring the sealing gasket is installed in the groove of the
top half of case.
7.
Reinstall 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/ORP sensor may fracture if the 9P temperature is allowed to go below
0°C/32°F.
•
The Conductivity cell cup should be kept clean. 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/ORP sensor in your 9P
should not be allowed to dry out.
•
Whenever the pH/ORP sensor is not in use make sure it is filled with
Myron L
®
Company pH/ORP Sensor Storage Solution and that the
protective cap is in place.
III. CLEANING SENSORS
A. Conductivity, TDS, Resistivity, Alkalinity, Hardness, 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, clean cell using isopropyl
alcohol or a foaming non-abrasive household cleaner.
•
Rinse out the cleaner, and your 9P is ready for accurate calibration then
measurements.
B. pH/ORP
: If the pH/ORP sensor dries out or becomes dirty, it may be
cleaned and/or reconditioned. For instructions on performing these
operations, download the full 9P Operation Manual from the
Myron L
®
Company website.
IV. pH/ORP 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.
