Commissioning Prepare the electrode for measuring as follows:

 Remove the watering cap from the electrode tip. Possible salt deposits in

the area of the watering cap do not affect the measuring characteristics

and can easily be removed with deionized water.

Note

Please keep the watering cap. It is required for the electrode to be stored.

Always keep the watering cap clean.

 Remove any gas bubbles behind the pH membrane by shaking.

 Connect the electrode to the meter.

 Calibrate the electrode according to the operating manual of the meter

and observe the following rules while doing so:
