 At the end of the third calibration point, the instrument returns automatically to measure mode.
 To perform a one- or two-point calibration, press the key
Note: electrode calibration is an essential operation for the quality and truthfulness of a
measurement. Therefore, make sure that the buffers used are new, unpolluted and at the same
temperature.
ATTENTION: Before proceeding with the calibration operations, carefully consult the safety data sheets
of the substances involved:
Calibration buffer solutions.

 Calibration with manual values
Example two-point calibration pH 6.79 e pH 4.65 (DIN19267)
:
 Access the Setup menu for pH and select in P1.1 Custom, press twice the key
measurement and position in pH mode
Press to enter the calibration mode.

 Rinse the electrode with distilled water and gently dab with paper towel. Dip the electrode in the first
pH buffer solution (e.g. pH 6.79).
