CALIBRATION PROCEDURE

• Remove the protective cap from the electrode. :

• Immerse the electrode tip into a new sachet of pH 7

calibration solution and allow the reading to stabilize.

• Adjust the pH7 calibration trimmer (on the front) to

display "7.0 pH".

• Open a new sachet of pH 4 calibration solution and

use a small quantity to rinse the electrode.

• Immerse the electrode tip into the pH 4 sachet and

allow the reading to stabilize.

• Adjust the pH4/10 calibration trimmer (on the front) to

display "4.0 pH".

• The calibration is now complete and the meter is

ready to take measurements.

• It is suggested to recalibrate the meter at least

once a month, after a prolonged stocking time

and after pH-electrode replacement.
