Soft Contact Lenses (contact lens zig is optional)
We have to prepare the mechanical jig for measuring a soft contact lens. The
procedures to measure a soft contact lens are as followings.
Step 1
Select the ‘SOFT CONTACT’ after choosing the ‘LENS’ item in the setup
screen.
Step 2
Remove the lens support and prepare the contact lens jig. Rotate two
jogs for the body to go to the middle of the structure.
Step 3
Clear the moisture on contact with lens toil. And then wait about in 10sec
to make its shape rounded.
Step 4
Take out the soft contact lens with a tweezers and place the soft contact
lens on the cap of the mechanical jig.
Step 5
Place the mechanical jig on the pin hole housing. Rotate two jogs for the
cross marker to go to the center of the display.
Step 6
Be sure that the heights of all score bars are higher than the criteria line.
Otherwise wait a little bit more, or move the soft lens a little bit so that the
height of score bars become equal or more than the criteria line.
Step 7
Press the ‘START RECORD’ button(
) to trigger the continuous
measurement. After a few second, Press the ‘STOP RECORD’
button(
).
You can specify the measurement duration at the User Setup Page. And
then if you turn on the ‘AUTO REC’ function, it is unnecessary for you to
press ‘STOP RECORD’ button(
) to stop the continuous
measurement. It stops automatically after the specified seconds.
