AT 030 7.2 Adjusting the swivel-mounted tonometer holder with square mounting
interface (version a)
34 / 60 319300-9120-000-GA-GB-240320
Lateral and vertical deviations of 1 mm do not impact the pressure
measurement precision.
In the case of greater deviations, first check the following:
Action 1. Is the tonometer positioned in front of the "correct" eyepiece?
2. Is the tonometer holder properly mounted?
3. Has the tonometer holder properly engaged in the operating
position?
If these checks do not yield satisfying results, align tonometer
holders which are mounted behind the stereomicroscope, as
described in section Adjusting the swivel-mounted tonometer
holder with square mounting interface (version a) [
}
34] and
Adjusting the swivel-mounted tonometer holder with round
mounting interface (version b) [
}
39]. It is not necessary to remove
the tonometer holder with the AT 030 mounted from the slit lamp.
NOTE! If, in case of the swivel-mounted tonometer holder
mounted on the stereomicroscope or Fundus VarioView and
in case of fixed tonometer holders, these checks do not yield
satisfying results, contact ZEISS Service.
Due to manufacturing tolerances (or wear) on the slit lamp it is
possible that, although the tonometer holder has been adjusted
accurately on one side, after shifting to the other side, the
adjustment is unsatisfactory. In this case, repeat adjustments alter-
nately on both sides until it is optimally adjusted in both positions.
NOTE! The adjustment steps can be carried out indepen-
dently of each other in any order. If adjustment according to
the above instructions is not successful, please contact
ZEISS Service.
