10.1 CHECK PROCEDURE WITH THE MEASUREMENT DRUM SET TO 0
Calibration Position – 0.05:
Rotate the measurement drum zero calibration downward
by the width of one calibration mark (see Figure 3). When
the sensor arm is in the free movement zone, it should
move against the stop in the examiner’s direction.
Calibration Po 0.05:
Rotate the measurement drum zero calibration upward
by the width of one calibration mark (see figure 4). When
the sensor arm is in the free movement zone, it should
move against the stop in the patient’s direction.
10.2 CHECK PROCEDURE WITH MEASUREMENT
DRUM SET TO 2
This is the most important check procedure, since
measurement of intraocular pressure in this area is highly
significant. We recommend running this check daily.
This check is made using the calibration arm (Figure
5). The arm is engraved with 5 circles. The Centre circle
corresponds to drum position 0, the two immediately
to the left and right to position 2, and the outermost
two to position 6. The arm is only marked on both sides
of 0 to maintain symmetry in order to calibrate.
Slide the bar in the support until one of the position 2
marks on the weight is located exactly at the reference
mark of the weight support (figure 5). With the weight
of the bar towards the examiner the 2 check can be
made.
When the drum position is 1.95 and/or 2.05, the
sensor arm should move from the free movement area
to the corresponding stop.
