30º = 40.0 diopters / 30º and 6.5mm / 120º = 52 diopters / 120º, the 30° prism value will be
aligned with the 43° “A” mark.
In other words, align the axial position of the major radius (that is, the axis of a negative
cylinder) with the prism value at the “A” mark on the prism support.
11. ROUTINE INSTRUMENT MAINTENANCE
Keeler recommends this routine maintenance be carried out by the user
frequently to ensure safe and accurate measurement. In the event of
the device being outside of the calibration tolerances, it is important to
send the device back to Keeler Ltd. or your local dealer for repair and
re-calibration.
11.1 CHECK PROCEDURE WITH TEST ARM SET TO 20
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 Test arm (Figure 5). The arm is engraved with 5 rings. The centre
ring corresponds to 0 mmHg, the immediate left and right rings correspond to 20 mmHg and
the outer rings correspond to 60 mmHg.
Slide the bar along the holder until the 20 mmHg reference mark aligns perfectly to the index
line on the holder. Ensure that the shorter portion of the test arm faces the examiner.
