Preparation for use
Note: Do not touch the probe cap with a hand, fingers or any surface that can scratch the cap.
Prepare the probe for use before calibration or sample measurement.
1. Make sure that the probe cap and iButton are installed correctly. The iButton label
should be up.
2. Make sure that the probe cap and iButton have the same lot code.
3. If a rugged probe, make sure that the shroud is installed before field use (refer to
Install the shroud on page 9).
Note: Damage to the sensing elements can occur if the shroud is not installed during field use.
Damage under these conditions is not covered by the product warranty.
4. Rinse the probe cap with deionized water. Blot dry with a lint-free cloth.
5. If dissolved oxygen monitoring periods are longer than 6 hours, condition the probe
cap for 72 hours. Calibrate the probe once every 8 hours.
Note: After 72 hours, the probe cap will reach a fully hydrated state.
