1.3. Cautions
zDon’t put anything on the lens supporter while it is turning on.
zHandle lens supporters carefully not to make some scratch on them.
zDon’t press the touch screen with a heavy pressure. Then it might be misaligned.
zDon’t execute the reading function when a frame or a pattern aren’t set.
1.4. Version Information
If you press “MENU > USER MENU > SYSTEM INFO” items, you can see some
system information and some versions.
zSoftware version : Software Main OS version
zResource version : Resource versions such as fonts and images.
zEEPROM Version : Permanent memory’s data version
zManufacting ID : The identical number of manufacturer
zFrame reader : The version of a tracer module

1.5. Optical System
The optical system in our blocker consists of aa Image channel and a refractive
channel. The image channel provides an observation image, the refractive channel
measures the center and the refractive powers of a lens. The refractive channel
moves forward and backward while it measures a lens.

1.6 Measurement Principle
Basic Principle of refractive channel
When there is no lens (0D state), parallel light that has transmitted the collimator lens
passes the 4 pinhole and makes image on CCD. In case of convex lens (lens with
plus diopter), parallel light that has transmitted the collimator lens converges through
the measuring lens, passes the 4 pinhole and then makes image on CCD. On the
other hand, in case of concave lens (lens with minus diopter), parallel light that has
transmitted the collimator lens diverges through the measuring lens and then passes
the 4 pinhole and at last makes image on CCD.
Basic Principle of refractive channel
While a refractive channel is on the home position, an Image channel gets
consecutive images. The images are shown at a screen or are tranfered to an image
processing engine to execute several jobs.

•LIVE IMAGE
-Shows the live image which is captured by the lensmeter camera.
•LIVE IMAGE
-Shows the live image which is captured by the lensmeter camera.
•LM MODE
-Calculate SPH, CYL, AXIS and PRISM continuously using the 4 signal points.
-You can identify the powers of the test lens.
•SETUP DIOPT
-Calculate some factors to execute the calibration using the lens on the table.
-Press the diopter box after finishing calculating.
-Set the lens diopter and then press ‘ENTER’ to save the specified diopter.
•SETUP POLY
-Press this button after you finish the calibration of standard lens set.
-That recalculates the polynomial coefficients of a setup data.
-And then save them.

3. Maintenance
•Don’t put anything on the lens supporter while the machine is starting up.
Otherwise, it might be malfunctioned.
3.1 “It is needed to setup prism” message
Follow the following procedures if you see “It is needed to setup prism” message at start-up.
Step 1. Go into the Lensmeter Calibration Display by press MENU >> CALIBRATION >> LENSMETER
Step 2. Press ‘D’ button at the left upper side to move the lensmeter block.
Step 3. Press 3 buttons for Lensmeter functions sequentially which are “LIVE IMAGE”, “SHOW INFO” and “LM
MODE”.
Step 4. Press “SETUP DIOPTER” button to calculate the information of 0 diopter.
Step 5. The white box’ at the top will show you 0.00. Press it.
Step 6. Press “ENTER” button at the numeric pad to save.
Step 7. Press “SETUP POLY” to reconstruct the diopter polynomial.
Step 8. Press the return button twice at the left upper side to go back the Main Display.

3.2 “Remove the object on the table and then turn off/on” message
Even though there is nothing on a lens supporter, if you see “Remove the object on the table and then turn off/on”
message at start-up, be in contact with your local distributor or the Huvitz service department.

3.3 Blocking Position calibration
Although the cross marker of a optic center is correct at the display, if the blocked position is incorrect for lenses
marked with 3 dots, progressive lenses or bi-focal lenses, it is needed for you to calibrate the blocking position.
Step 1. Put an adaptor at the adaptor holder.
Step 2. Put the lens supporter for the Digital Scanning on the normal lens supporter.
Step 3. Click “BLK CENTER” button at “MENU > CALIBRATION > BLOCKER” page.
Step 4. If the red cross marker and a center hole of the adaptor aren’t coincided as you see in the above picture,
move the cross marker to locate the center of the hole using 4 arrow buttons at the bottom.
Step 5. If you moved the cross marker, press the save button at a top area to apply your calibration.
Step 6. If you repeat from Step 1 to Step 4, you can identify whether your calibration is done correctly or not.
