Prn(P0.0) PRINTER TRANSMISSION

If you have purchased the optional printer, you can transmit saved data

via infa-red signal to begin printing. Make sure you switch on the

printer and point the infa-red emitter to the printer’s receiver.

1. Press OK and display will show Prn (P0.1)flashing, indicating that

transmission is in progress.

2. When transmission is completed, display will stop flashing and

return to Prn P0.0.

3. Press f>to go to next parameter.

CLr(P1.0) CLEAR MEMORY

This setting will clear all the saved memory in the unit.

1. Press OK and display will show P1.1 with n(No) flashing.

2. Press f>once to select between Y(yes) or n(No). If you select Y

(yes) and press OK, all memory will be cleared. Otherwise select n

(No) then press OK, display will return to CLr (P1.0).

3. Press f>to go to next parameter.

Unt(P2.0) UNIT OF MEASUREMENT

This setting allow you to set the unit of measurement for temperature or

DO.

1. Press OK and display will show Unt (P2.1)with °C flashing.

2. Press f>to change between °F or °C.

3. Press OK to confirm setting.

4. Do (P2.2) will be displayed and ppm flashing.

5. Press f>to change between mg/l or ppm

6. Press OK to confirm setting, display will return to Unt (P2.0).

4. Press f>to go to next parameter.

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.

1. If you are making measurement at sea level and in fresh water, you

can skip this section. Press f>to go to next parameter.

2. To change, while in COF (P3.0), press OK to begin setting and

display will show 760mmHg (P3.1)for altitude setting.

3. Press f>or <eto change the value. The pressure should be the

same altitude where you are making the measurement. Below is a

chart to correlate altitude against pressure:

ALTITUDE

1,829 6,000 609

4. Press OK to confirm the setting, 101.3 kPA (P3.2)will be displayed

for setting pressure in kPA. Change this value if you have an

accurate pressure meter as a reference.

5. Press f>or <eto change this value.

6. Press OK to confirm changes and display will show 0.0ppt (P3.3).

Here you can change the salinity value to that of the water you are

about to measure.

7. Press f>or <eto change this value.

9. Press f>to go to next parameter.

Rdy(P4.0) ENDPOINT INDICATOR

This setting allow you to switch ON or OFF the endpoint indicator.

When a measurement is still in progress, the READY sign will flash.

When the READY sign will stop flashing, it indicates that a stable

endpoint reading has reached. This will be helpful to eliminate

guesswork. In some special case, especially where the reading is

exceptionally slow in response, switch OFF the indicator for

indepandent user’s judgement.

1. Press OK and display will show rdy P4.1 with OF (off) flashing.

2. Press f>to change to on or OF.

2. Press f>or <eto change to 20, 30, 40, 60, 90 or 120 minutes

shutoff.

3. Press OK to confirm setting, display will return to Aut (P5.0)

4. Press f>to go to next parameter.

2. Press f>once to select between Y(yes) or n(No). If you select Y

(yes) and press OK, all setting will be cleared and reset to factory

default. Otherwise select n(No) then press OK, display will return

to rSt (P9.0).

3. Press f>to return to beginning.

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.
