1. Remove the storage cap from the top of the

calibration chamber and replace it with the vented

calibration cap.

2. Place the sponge wafer in the bottom of the

calibration chamber and saturate with approximately

10 mL water.

3. Gently dry the instrument and sensing material with a

paper towel, making sure there is no water or debris

on the instrument or on the sensing surface.

4. Place the instrument into the calibration chamber

about 2.5 cm (1 in.) above the water-saturated

sponge.

5. Allow 5 to 10 minutes for temperature stabilization

prior to starting the calibration procedure. Do not

leave the instrument in the calibration chamber for

more than 30 minutes. This can allow condensation to

form on the sensing material, which will produce false

low readings after calibration. If condensation does

occur, remove the instrument, dry the sensing

material, place the instrument in the chamber, and

calibrate.
