2.5. How to Set with 2 ∆ and 4 ∆
This calibration is for enhancing the measurement accuracy for the
peripheral area. We should use the 2
∆
and 4
∆
lenses. 4
∆
lens is not
included in the standard lens set. So, you can get it from the
manufacture or you can use one in the trial lens set. But it should be
around 4
∆
such as
–
3.8
∆
~ 4.2
∆
.
A. First, change the Prism Display as the P-B.
B. Press the ‘ MODE ’ ( ) button to go into the Basic Display II at
the Basic Display I.
C. Place the 4
∆
lens on the lens supporter.
D. Rotate it the Base value equal 1deg.
E. Then, press the ‘ D-SUN ’ ( ) button to store some information.
F. Rotate it to become the Base value increase by the 22 or 23 deg.
G. Then, press the ‘ D-SUN ’ ( ) button to store some information.
H. Repeat From Step F ~ to Step G to the Base value equal to 337
deg or 338 deg.
I. The all spots that should be marked are as the table at the next
page.
J. Repeat From Step D ~ to Step H with 2
∆
.
K. Press the ‘ EXIT ’ ( ) button to go back to the Basic display I.
L. Press the ‘ CLEAR ’ ( ) button for a while to go into the
Calibration Display.
M. Press the ‘ CHECK ’ button for a while and then Prism Compensation
Information Display appears.
N. Press the first button to calculate the appropriate coefficients.
O. Press the second button to calculate the ratio between 4
∆
and 2
∆
.
P. Finally the
‘
SAVE
’
button to save.
