Tono-Pen AVIA Vet Tonometer Tones
The Tono-Pen AVIA Vet tonometer generates two different tones.
A “BEEP” will sound when:
• Power Up Mode fails
• Verification Mode fails
• Applanation Mode starts
• IOP testing is completed
• IOP values are out of range (>99)
• At various points during the verification test.
A “CHIRP” will sound when:
• A valid IOP measurement has been taken during applanation.
