SERVICE MANUAL
4 - SERVICE MODE 4-2-1 Field “ZERO” and Position of Marker #1 The default value of this field is “16” and is given by the manufacturer of the biometry probe. This value can be different with another manufacturer and it depends on the size of the probe tip. Adjusting “Zero” will impact the mesured values during acquisition as follows: - decreasing ZERO by 1 will increase the mesured value by 0.04mm (with the “Position of marker #1 in contact” of the general setup page as 0.00mm). The test block has been developed as a standard in contact technique to calibrate the measurement of the eye and adjust the corresponding parameters. Follow the steps below to enter the correct value in “Zero”. 1. Make a biometry acquisition on the test-block: - from the Main page, press F1 to go to the General Setup page, - move the cursor to “Position of marker #1 in contact” - press F1 and follow the instructions on the screen as below: Put the probe on the Test-Block With a drop of water. Press "F1" to Start and then to Stop the measurements. Note : the result is corrected by the position of the first marker : +0.00 mm
Best = 10.04 mm L = 10.08 mm
2. The mesured value X (displayed as “Best”) must be 10.00 < X < 10.11mm 3. If X is not within this interval, modify ZERO so that X will fit into these limits (knowing that 1 unit of ZERO corresponds to 0.04mm of X). Ex: X=9.96mm, ZERO can be adjusted to: 12 < ZERO =< 15 Note: Instead of modifying ZERO, this correction can also be done by entering the value in the “Position of marker #1 in contact” field of the general setup page.

The default value of this field is “6”. It defines the sharpness of the retinal peaks in order to freeze the A-scan when the probe direction is in the visual axis, reaching the macula area. This value means that the slope is raised up by 6 digital points. It appears that the retina slope test of “4” is perfect for physicians using the Prager shell in immersion technique. This shell holds the probe in its axis and helps to keep it perpendicular to the macula.
If the physician is not using the immpersion technique, but the contact one, and has difficulties to find the visual axis, the Retina Slope Test should be set to “6”. Increasing this value will make freezing easier.
4-2-3 Field “D2/LOW DYN” The recommended value for this field is “20”. The entry range is 15 to 25dB. It corresponds to the dynamic scale to avoid distorsion during acquisition. The dynamic value is inversely proportional to the Gain value (as specified in the user setup). The display is the same as above except that the highlighted zone is on “D2/Low Dyn”.

5 - PROBE CALIBRATION 5-1 BIOMETRY PROBE Calibrating the biometry probe consists in performing an acquisition on the biometry test block (on the front panel) then enter the correct value of “ZERO” and “Position of Marker #1 in contact” in the hidden page. Follow carefully. the procedure as detailed in chapter 4-2-1 Note: It is recommended to check the position of Marker #1 in contact when changing probe. If the measurement is not correct, you have to perform a calibration of the probe (see chapter 4-2-1). If the probe is not correctly calibrated, the measurements of the patient eye will not be accurate and the values are incorrect.
