Changing The Probe Tip - Welch Allyn 9020 Manual

Welch Allyn 9020 Infrared Tympanic Thermometer

CHANGING THE PROBE TIP

A damaged probe tip can tear the ultra-thin film in the probe covers. A
temperature taken with a torn probe cover may result in a measurement
that is higher than the actual temperature.
Periodically inspect the plastic probe tip for nicks or other damage, and
replace if necessary.
MATERIALS NEEDED
1. Advance the slide to extend the probe tip.
2. Manually remove the probe cover to expose the probe tip.
3. Remove the probe tip by turning it counterclockwise (Figure E).
Discard the damaged probe tip.
4. Install the new probe tip by turning it clockwise, then hand-tightening
(5 inch-lbs.) until it is positioned snugly against the base of the probe.
Do not over-tighten the tip.
5. As a precaution, clean the sensor lens to remove any dust or debris
that may have adhered to the exposed lens during replacement of the
probe tip.
Follow the steps for "Cleaning the Probe Sensor Lens – Method 2"
described earlier in this section of the manual.
