Setup (continued)

Calibration Procedure (continued)

If several consecutive attempts at checking the calibration are unsuc-

cessful:

• Loosen or remove the Ocu-Film Tip Cover from the Tono-Pen XL

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 XL fails to yield a [Good] calibration, call Reichert

Technical Service.
