Setup (continued)
Calibration Procedure (continued)
If several consecutive attempts at checking the calibration are unsuccess-
ful:
• Loosen or remove the Ocu-Film Tip Cover from the Tono-Pen VET
probe tip and repeat the calibration check.
• Spray the probe tip with compressed gas, and repeat the calibration
check.
• Replace the batteries and repeat the calibration check.
Note: If [CAL] appears followed by a row of four dashes [- - - -], the unit
did not go into calibration mode. To correct this, depress the but-
ton quicker two times or slower two times.
Note: Do not take measurements with the instrument if two consecutive
[good] calibration checks cannot be obtained. The instrument
will not take a measurement when the prior calibration check was
[bAd].
Note: If the Tono-Pen VET fails to yield a [Good] calibration, call Reichert
Technical Service.
