to measure the RIGHT eye.

operator defined measurement bias while in
Mapping Measurement Mode. (See sections

shown in the upper left-hand corner).
12.3.11 Gently position the probe tip on the cornea as described in section 4.4. The Pachmate 2
will automatically take a single measurement when the probe is properly applanated.
• For each successful measurement taken the device will emit a quick ‘beep’.
• If the device is not able to obtain a
measurement within 3 seconds, the device will
emit a long beep and the ‘Poor Applanation’
message will be displayed.
• If the ‘Poor Applanation’ message is displayed, attempt to reposition the probe tip for
proper applanation. Once the probe tip is in proper alignment, the device will
continue measurement.
