Power Up Mode
Pressing the activation button initiates the battery life, LCD,
Transducer Assembly, and electronic self-test. A successful power-
up puts the device automatically into applanation mode.
Applanation Mode
The user will have 15 seconds after pressing the activation button to
obtain the first applanation. 2-6 applanations are needed to acquire
an IOP value. During applanation mode, the LCD will display the
IOP and number of applanations collected. After 6 applanations are
collected, the LCD will display the finaI OP along with a statistical
confidence indicator. After 25 seconds, the device will automatically
go into a sleep mode. If the activation button is pressed again
the data will be cleared and the unit will be ready to start another
measurement sequence.
Verification Mode
Pressing and holding the activation button for 5 seconds initiates
an electronic self test mode. See Tono-Pen AVIA Vet Tonometer
Verification section for details.
Sleep Mode
A power-saving mode automatically activates after 25 seconds of
non-use. Pressing the activation button will initiate a power-up
mode.
