Cleaning Instructions
The Tono-Pen VET 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 VET 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 VET
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 VET 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 VET tonometer. Use of any other type of
branded tip cover may affect readings or may void your warranty.
Note: Always store the Tono-Pen VET tonometer with an Ocu-Film
+ tip cover installed to protect the tonometer tip from dirt and
contaminants. contaminants.
