Cleaning Instructions

The Tono-Pen XL tonometer may have difficulty

taking measurements or display “Fail” after a

verification when its tip is dirty and requires

cleaning. When the Transducer Assembly of the

tonometer has dirt and contaminants in the tip,

cleaning of the tip is necessary. When the tip

contains contaminants, it cannot move freely and

the Tono-Pen XL may have erratic readings and

then show a “Fail” verification.

1. Remove Ocu-Film + tip cover from the tonometer, if one is installed.

2. Using canned air, place the tip of the Transducer Assembly against

the outlet of the canned air as shown in Figure 8.

3. Blow the canned air into the tip of the tonometer for approximately 3

seconds.

Note: It is necessary to blow canned air directly into the tip so that the

contaminants are pushed out.

4. After cleaning the tip with compressed air, the Transducer Assembly

will be cold. Allow the Transducer Assembly to warm to room

temperature.

5. Perform the tonometer verification as indicated in the Tono-Pen XL

Tonometer Verification section of this manual.

Note: If the tonometer does not “Pass” the verification procedure, then

repeat the above cleaning instructions. Do not clean more than

3 times in a row. If the tonometer still will not pass verification,

contact Reichert.

Note: Never use the Tono-Pen XL tonometer without an Ocu-Film + tip

cover installed.

Note: Ocu-Film + tip covers are the only manufacturer approved covers

for use with the Tono-Pen XL tonometer. Use of any other type of

branded tip cover may affect readings or may void your warranty.

Note: Always store the Tono-Pen XL tonometer with an Ocu-Film

+ tip cover installed to protect the tonometer tip from dirt and

contaminants. contaminants.
