SERVICE MANUAL


6-1-1 Field “ZERO”and Position of Marker #1The default value of this field is “0” and is given by the manufacturer of thebiometry probe. This value can be different with another manufacturer and itdepends 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 (withthe “Position of marker #1 in contact” of the general setup page as0.00mm).

The test block has been developed as a standard in contact technique tocalibrate the measurement of the eye and adjust the correspondingparameters. 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 the General Setup button,- click on the “Position of marker #1 in contact” field (Biometry or ProBeam probe).- press the Biometry Test (or ProBeam Test) button and follow the instructions on the screen as below:

2. The mesured value X (displayed as “Best”) must be10.00 < 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 thevalue in the “Position of marker #1 in contact” field of the general setup page.

6-1-2 Field “RETINA SLOPE TEST”The default value of this field is “6”.It defines the sharpness of the retinal peaks in order to freeze the A-scan whenthe probe direction is in thevisual axis, reaching the macula area. This valuemeans that the slope is raised up by 6 digital points.

It appears that the retina slope test of “4” is perfect for physicians usingthe Prager shell in immersion technique. This shell holds the probe in itsaxisand helps to keep it perpendicular to the macula.

If the physician is not using the immpersion technique, but the contact one, andhas difficulties to find the visual axis, the Retina Slope Test should be set to “6”.Increasing this value will make freezing easier.

SERVICE MANUAL

6-2 TOUCH SCREEN CALIBRATIONThe position of the touch-screen-sensitive area can be calibrated.It can be necessary after a transport, a screen assembly changing, a softwareupgrade or other wich could change the touch screen calibration.

To use the calibration software, it is necessary to access the desk ofWindows®:

1- From the Home page, press the General Setup button.

2- Press the Windows Access button.

NOTE: To obtain a better result, it is recommended to press the screen with athin plastic stick, like a PDA pencil.

At the end, exit the TouchUtility software.

To calibrate the touch-screen, use the TouchUtility software. Click on theDevice tab then on the 9 point button .

Follow the procedure displayed on the screen.


6-1-3 Field “D2/LOW DYN”The recommended value for this field is “20”. The entry range is 15 to 25dB. Itcorresponds to the dynamic scale to avoid distorsion during acquisition. Thedynamic value is inversely proportional to the Gain value (as specified in thephysician setup).

6-1-4 Pachymetry activationPachymetry needs a keycode to activate it. Refer to the Keycode activationguide to know the right sequence.

28 Rev 12-2008

SERVICE MANUAL

6-3-3 B-probe (only for COMPACT TOUCH)


Calibrating the biometry probe consists in performing an acquisition on thebiometry test block (on the front panel) then enter the correct value of “ZERO”and “Position of Marker #1 in contact” in the hidden screen.

Follow carefully the procedure as detailed in chapter 5-2-1

Note: It is recommended to check the position of Marker #1 in contact when changingprobe. If the measurement is not correct, you have to perform a calibration of theprobe (see chapter 5-2-1). If the probe is not correctly calibrated, themeasurements of the patient eye will not be accurate and the values areincorrect.

This feature requires an activation keycode (see chapter 6-1-4).The pachymetry probe must be calibrated before use:

1. In the hidden page (see chapter 6-1), press the Pachy Calibration button.

2. The following screen is displayed:

3. Follow the instructions carefully and press Start .

4. Repeat the process 4 or 5 times and check that the displayed values xxx are stable (±10).

Note: It is recommended to perform a new calibration when changing probe, inorder to improve the accuracy of acquisition.

6-3 PROBE CALIBRATION6-3-1 Biometry probe

The different parameters for using the B-probe with the COMPACT TOUCHare including in the probe. So it is not necessary to calibrate the B-probe.
