6 Calibration

Prerequisites for calibration

- Ideally, the electrode will produce 0 mV at pH 7.00

- The ideal ambient temperature is 25 °C

Required equipment for calibration

- pH Electrode

- 2 pH solutions (pH 7.00 and pH 4.00)

Calibration procedure pH 7

1) Rinse the electrode in distilled water completely.

2) Connect the pH electrode to the meter and immerse it into the relevant calibration solution.

3) Power on the instrument.

4) Press the "CAL" key. The desired calibration value pH 7 will appear.

The display will show:

7.00

CAL

5) Press the "ENTER" key to confirm.

Calibration procedure pH 4

1) Rinse the electrode in distilled water completely.

2) Connect the pH electrode to the meter and immerse it into the relevant calibration solution.

3) Power on the instrument.

4) Press the "CAL" key. The desired calibration value pH 7 will appear.

The display will show:

7.00

CAL

5) Press the ▼ (Down) key until the desired calibration value appears:

4.00

CAL

6) Press the "ENTER" key to confirm.

Calibration procedure pH 10

1) Rinse the electrode in distilled water completely.

2) Connect the pH electrode to the meter and immerse it into the relevant calibration solution.

3) Power on the instrument.

4) Press the "CAL" key. The desired calibration value pH 7 will appear.

The display will show:

7.00

CAL

5) Press the ▼ (Down) key until the desired calibration value appears:

10.00

CAL

6) Press the "ENTER" key to confirm.

7 Important information on the calibration

- Before and after immersing the electrode into a pH solution, rinse it with distilled water.

- Calibrate each pH solution twice, if possible.

- It is recommended to calibrate in two steps: pH 7 first, followed by pH 4, then calibrate pH 7

again and then pH 10.

- If the calibration solution deviates by 2 pH, “ERR”will appear in the display.

8 Clear calibration

1) Power on the instrument.

2) Press the "CAL" key.

The following will be shown in the display:

7.00

CAL

3. Press the ▼ (Down) key until the following appears:

CLr

CAL

4. Press the "ENTER" key to confirm.

When the calibration has been cleared, the display will show:

End

9 Measuring procedure

1) Power on the instrument.

2) Immerse the electrode into the desired solution.

3) The instrument will display the measured pH value.

4) Rinse the electrode with distilled water.

12 Disposal

For the disposal of batteries in the EU, the 2006/66/EC directive of the European Parliament

applies. Due to the contained pollutants, batteries must not be disposed of as household waste.

They must be given to collection points designed for that purpose.

In order to comply with the EU directive 2012/19/EU we take our devices back. We either re-use

them or give them to a recycling company which disposes of the devices in line with law.

For countries outside the EU, batteries and devices should be disposed of in accordance with

your local waste regulations.
