5. Follow on-screen prompts to confirm the buffer value.
6. Repetiu per a les solucions tampó següents.

5.2.2. Redox Calibration

Redox electrodes typically do not require calibration in the same way as pH electrodes. However, their functionality can be checked using a known Redox test solution.

5.3. Prendre Mides

1. Ensure the device is calibrated.
2. Rinse the probe(s) with distilled water and blot dry.
3. Immerse the probe(s) into the sample solution. Ensure the sensing part of the probe is fully submerged.
