Maintenance
Clean the probe
Keep the probe cap free of deposits for the best measurements.
Note: Do not touch the black colored substrate of the probe cap. Do not use alcohol or other
organic solvents to clean the black colored substrate of the probe cap. These solvents cause
damage to the probe cap.
1. Remove the shroud (refer to Remove the shroud on page 9).
2. Gently clean the probe cap with a mild detergent, water and a soft cloth or cotton
swab. Do not remove the black colored substrate from the probe cap. Do not scrub
the probe cap or lens.
3. If water is present between the probe cap and lens:
a. Remove the probe cap.
b. Blot dry the probe cap and lens with a soft dry cloth.
c. Install the probe cap.
4. Install the shroud (refer to Install the shroud on page 9).
