Operation
The O-Ring
There is an O-Ring seated at the end of the threads on the probe. As a preventative maintenance
measure, and to ensure that the nose cone of the probe unscrews easily, do not clean or remove
the lubricant from the O-Ring. If the O-Ring appears to be void of any lubricant, or if the nose
cone itself was difficult to remove, apply a high-quality synthetic lubricant such as those
considered “food-grade.” Refer to Figure 2 and apply as described in the instructions that
follow.
Figure 2: O-Ring care.
A: Cotton swab.
B: Lubricant
C: O-Ring (enlarged for detail).
1. Place a small drop of lubricant at the front outer surface of the O-Ring.
2. Using your finger or a cotton swab, spread a thin layer of lubricant completely around the
front and outer surface of the O-Ring. Ensure that no lubricant spreads into the threaded
area of the nose cone. Only a thin layer of lubricant is necessary. Excessive application or
build-up may affect test results.
