Icare tonometer TA01i manual
To exit the old values search, press the measurement button. The display will now show the word
‘Old’. Press either selector button to access other functions (00=measurement, End=turning OFF).
TURNING THE TONOMETER OFF
(Figures 10-12)
Press either selector button until the display shows ‘End‘. Press the measurement button for two
seconds - the display will show ‘byE’ and the tonometer will switch off. The used probe will be
partially ejected. Use the used package to remove it from the tonometer. Ensure that you dispose
of the probe properly.
ERROR MESSAGES
To clear error messages, press the measurement button, after which the measurement can be
repeated. The following messages may appear:
MESSAGE STATE DESCRIPTION
bAtt The batteries are low. Replace the batteries.
E 01 The probe did not move
at all.
If this error message is repeated, turn the tonometer so
that the collar faces down for a short time. If the error
message is repeated, remove the probe base and replace it
with new ones (see figure 15).
E 02 The probe did not touch
the eye.
The measurement was taken from too far away.
E 03 The probe speed was
too low.
The measurement was taken from too far away or the
tonometer was tilted too far upwards.
E 04 The probe speed was
too high.
The tonometer was probably tilted downwards. Make sure
that the central groove is in the horizontal position.
E 05 The contact with the eye
was too “soft.”
The probe probably made contact with the eyelid.
E 06 The contact with the eye
was too “hard.”
The probe made contact with the opening eyelid or
calcification in the cornea.
E 07 The probe measurement
signal detected by the
tonometer was unusual.
The probe may have made contact with a peripheral part of
the cornea or the probe was twisted or otherwise inserted
incorrectly. If this error message repeats, remove and
replace the probe.
E 09 Bad data. An erroneous measurement for a reason other than those
described in E01−E07.
