2. Place the sponge wafer in the bottom of the calibration cup and saturate the sponge

wafer with approximately 10 mL clean water.

3. Gently dry the probe and sensing material with a paper towel. Ensure that the probe

and the sensing surface are free of water and fouling.

4. Place the instrument into the calibration cup.

5. Wait 5 to 10 minutes for temperature stabilization prior to calibration.

Note: Do not leave the instrument in the calibration cup for more
than 30 minutes. This can cause condensation to form on the
sensing material, providing false low readings after calibration.
