Applanation
1. Press and release the activation button once to initiate the
applanation mode.
2. A brief display of
[88
888]
will flash on the LCD, a double row
of dashes
[===]
will be displayed, the green LED will turn on,
and a “beep” tone will sound, indicating the Tono-Pen AVIA Vet
tonometer is ready to measure intraocular pressure.
3. Tap very lightly and briefly on the corneal surface. The device
will chirp and the IOP measurement will be displayed in the
mmHg field on the LCD, and the DATA field will increment for
each valid IOP reading obtained.
4. When another beep tone is heard, indicating 6 applanations
have been read, the green LED will turn OFF, and the averaged
IOP measurement will appear above the mmHg field, and the
statistical confidence indicator will appear above the DATA field
on the LCD.
Note:
If at least 2 applanations were read, the avergae IOP will be
displayed after a 4 second delay, along with the statistical
confidence indicator.
Note:
After pressing the Activation button, do not shake the
Tono-Pen AVIA Vet tonometer as it may register a reading.
If this occurs simply re-press the Activation button and start
the measurement again.
The user will have 15 seconds after pressing the activation button to
obtain the first applanation before the Tono-Pen AVIA Vet tonometer
will initiate the Sleep Mode, indicated initially by the display of
a single row of dashes
[---]
, followed by a blank display. The
applanation mode may be initiated by pressing the activation button.
If any error codes appear on the LCD after the final beep, the
applanation procedure must be repeated.
