COF(P3.0) SENSOR CORRECTION (ALTITUDE & SALINITY)
Atmospheric pressure and salinity has an effect on to sensor. If you
make measurement at different altitude, a correction is necessary to
compensate for the pressure effect. Similarly, different salinity in water
will also affect measurements and require compensation. This meter
will automatically compensate these errors and give accurate
measurements if they are carefully set.

7. CALIBRATION:
7.1 Ensure you are in an environment, which is open with good air
circulation and not crowded. If you in a higher altitude above sea level,
setup the altitude compensation (see Page 6 on COF – P3.0) before
you continue.
7.2 Hold the probe in air with the sensor facing downwards and switch on
the unit. Wait at least 10 minutes for the sensor to get stabilized. Set
the auto-shutoff timing to 30 minutes or longer to prevent auto-shutoff
(see Page 7 on Aut - P5.0).
7.3 After sensor is polarized, press the CAL button to activate calibration.
The display will show reading in %while the Ready sign flashes.
7.4 When the Ready sign stops flashing, press the OK button.
7.5 Display will show 100% reading and calibration is completed.
7.6 Press the %-ppm button to switch to ppm or mg/l reading and proceed
to take a measurement in water.
CALIBRATIOIN FAILURE:
7.7 If the unit is not able to calibrate or gives a very low reading, it is
possible that there are air pocket between the membrane and the
probe tip. Carefully study section 9 to understand the probe assembly.
7.8 Place the probe horizontally on the table and tap the probe head on the
table lightly several times to allow any air pocket to be filled with
electrolyte. Recalibrate again.
7.9 If calibration still fails, remove the probe guard, loosen the LockRing
Assembly and repeat step 7.8, replace the Probe Guard and
recalibrate.
7.10 If calibration still fails, it could be that the membrane is damaged or the
electrolyte is expired.
7.11 Perform a full membrane change as in section 9.

8. MAKING MEASUREMENT:
8.1 Always calibrate the meter before a series of tests.
8.2 Avoide switching off the unit if a series of tests are to be made, this is
to save time so you do not have to polarize the sensor everytime the
unit is switched on.
8.3 Dip the sensor into the water and the required depth.
8.4 This meter utilizes a polarographic electrode, which consumes oxygen
on the membrane surface. A constant stirring or jiggling of the
sensor probe is required during measurement.
8.5 When the Ready sign stops flashing, it indicates a stabilized endpoint
reading has reached. You can now take the measurement.
8.6 Press the HOLD button to freeze the display as desired. HLD will
appear on the top left of display. Press again to release it for another
measurement.
BACKLIGHT FUNCTION
8.7 Under dim or dark environment, the display can be illuminated with a
backlight. Press both the HOLD and OK buttons and backlight will be
switched on for 10 seconds.
SAVING DATA TO MEMORY
8.8 To save the displayed data into the meter’s memory, press the SAVE
button.
8.9 The digit 01 will appear on the right side of the display, indicating that
the last reading is stored in data number 1.
8.10 99 data can be saved together with date and time of measurement.
8.11 To recall the saved data, press and hold down the RECALL button until
REC appear flashing on the left side of the display.
8.12 Follow the blue key function in Page 4 under RECALL MEMORY
FUNCTIONS, to recall the desired data.
8.13 Press EXIT to return to measuring mode.
8.14 To clear all data, follow the instructions under SETUP on page 5 of CLr
(P1.0)

9. DO PROBE ASSEMBLY & MAINTENANCE:
9.1 The DO probe is one of the main components in the measuring system.
Keeping the sensor in good conditions will ensure prolong of operation.
9.2 The Probe consist of several parts and it is important to understand the
construction:
9.3 The membrane will allow oxygen to permeate onto the Cathode and
Anode to make measurement. It can be damaged or punctured.
9.4 To replace the membrane, unscrew the Probe Guard and remove
item X& Yas above. You may need a knife assist in separating
item Y.
9.5 Unscrew the Electroyte Refill Port and drain away the electrolyte.
9.6 Clean and rinse the probe tip with distilled water, use a tissue paper to
polish the probe tip if required. DO NOT USE sand paper.
9.7 To re-assemble the probe, place the new O Ring on the probe tip X.
9.8 Push in place the Membrane Cap onto the probe tip Y.
9.9 Place the probe horizontally with the Refill Port facing up.
9.10 Extract the fresh electrolyte with the syringe and gradually fill the
Electrolyte container till half filled.
9.11 Tap on the table to allow electrolyte to filled to the probe tip. If air is
trap between the probe tip and membrane, it will cause calibration and
measuring problem (E01, e03). Unscrew Probe Guard, slightly
loosen Membrane Cap then replace Probe Guard.
9.12 Replace the Probe Guard and screw tight Z.
9.13 Then fully fill the container; replace the Oring, Washer and tighten the
Screw onto the Electroyte Refill Port.

Electrolyte Refilling:
9.14 From time to time, electrolyte may evaporate and dry out.
9.15 Unscrew the Electrolyte Refill Port and refill with elelctroyte.
9.16 The electrolyte may also degrade after prolong usage. When bubbles
are seen in the electroyte container or the sensitivity of the meter
becomes low, or error messages of inaccurate reading, the electrolyte
should be replace completely.
9.17 Change the membrane and replace electrolyte as in 9.4 to 9.13
Probe Maintenance:
9.18 After about 50hours of continuous use, the Probe-Tip anode or
cathode may get tarnished due to polarization.
9.19 Disassemble the probe and drain the electrolyte. Rinse probe tip with
distilled water and polished it with diamond power paste. Rinse and
re-assemble with new membrane and electrolyte as 9.8 to 9.13
10. TROUBLESHOOTING & ERROR CODES
