next Parameter.

MEASUREMENT

Rinse the electrode with distilled water or sample prior to start measurement.

Fill the measuring cap with sample, switch on the meter and immerse the Tester in sample and wait for stabi-

lity, when stability icon appears on display take the reading.

During measurement make sure that pH electrode membrane is free from air bubbles, and that there

is not any air bubble around or between conductivity sensor.

Calibration procedure

CONDUCTIVITY (COND1)

1. Power ON the meter by pressing the key.

2. Rinse the probe with distilled water.

3. Immerse the probe in the calibration solution (1413µS or 12.88 mS), wait for stability.

4. Press CAL key.

5. The meter will start calibration procedure and will recognise automatically the standard

used.

6. When calibration is stable press to conrm and complete the calibration.

7. The standard value will ash for 3 times and then the meter will go into the measure-

ment mode.

8. If the 2nd point calibration is required then rinse the probe with distilled water and im-

merse in the second standard solution (1413µS or 12.88 mS), wait for stability .

9. Repeat the points 4 to 7.

10. The calibration process is completed and the meter is ready to use.

Note: Anytime press key to abort and exit from calibration procedure.

• Reading based on theoretical cell value C=1

• Standard solution

TDS (COND 1)

When the meter is set to read TDS (see Paragraph “Setup Menu” at page 5), then the calibration is done on

TDS with 1 or 2 points.

The calibration procedure for TDS is the same as for conductivity.

PH (PH 1)

1. Power ON the meter by pressing the key.

2. Rinse the electrode with distilled water.

3. Immerse the electrode in the 1st bu󰀨er solution pH7.0 and wait for stability.

4. Press CAL key.

5. The meter will start calibration procedure and will recognise automatically the standard

used.

6. When calibration is stable press to conrm and complete the calibration.

7. The standard value will ash for 3 times and then the meter will ask for next point for calibration.

If only 1-point calibration is required then press to nish and exit.

8. If the 2nd point calibration is required then rinse the electrode with distilled water and immer-

se in pH4.0 or pH10.0, wait for stability.

9. Repeat the points 4 to 7.

10. The calibration process is completed and the meter is ready to use.

Note: Anytime press key to abort and exit from calibration procedure.

Note 2: When the rst point calibration is conrmed (point 7) if the sensor is not removed from the bu󰀨er

solution, the instrument may give wrong bu󰀨er error.

meter to be measured (green backlight during measurement). Immerse the Tester in sample and wait for

stability, when stability icon appears on display take the reading.

During measurement make sure that pH electrode is free from air bubbles, and that there isn’t any air

bubble around or between conductivity sensor.

4. Press to enable the value changing of the selected parameter.

merse in the 2nd Standard, wait for stability.

9. Repeat the points 4 to 7.

10. If the 3rd point calibration is required then rinse the electrode with distilled water and im-

merse in the 3rd Standard, wait for stability.

11. Repeat the points 4 to 7.

12. The calibration process is completed and the meter is ready to use.

2. Rinse the electrode with distilled water.

3. Immerse the electrode in the 1st bu󰀨er solution pH7.00 and wait for stability.

4. Press CAL key (blue backlight during calibration).

5. The meter will start calibration procedure and will recognise automatically the standard

used.

6. When calibration is stable, press to conrm and complete the calibration.

7. The standard value will ash for 3 times and then the meter will ask for next point for calibrat-

ion. If only 1-point calibration is required then press to nish and exist.

8. If the 2nd point calibration is required then rinse the electrode with distilled water and im-

merse in pH4.01 or pH10.01, wait for stability, otherwise press ESC to nish and exit.

9. Repeat the points 4 to 7.

10. If the 3rd point calibration is required then rinse the electrode with distilled water and im-

merse in the last bu󰀨er, wait for stability, otherwise press ESC to nish and exit.

11. Repeat the points 4 to 7.

12. The calibration process is completed and the meter is ready to use.

Note: Anytime press ESC key to abort and exit from calibration procedure.

Note 2: In case multipoint calibration is performed it is better to start from the lower value standard rst and

then go increasing.
