Example:
Let's say our 500 unit exposure gave us 600 mj. That
means we got 1.2 mj per unit or a 1.2:1 ratio. The objective is to
get a 1:1 ratio. To get that we would multiply our current
calibration number of 500 by 1.2, 500 x 1.2 = 600.
•
Since we are working with the Upper Tray Top Surface or
[Ut]
, we have
to change the preset 500 to 600.
•
Change to 600 as described earlier in Calibration Procedures Section.
Remember:
The lower the CAL number, the longer the exposure and
the higher the mj reading.
•
Now make a 500.0 unit exposure with the UV meter and record the
resulting mj reading. It should be 500 ±3%. Perform this procedure on
the remaining three surfaces.
[_SEL]
Press
1, 2, 3 t 4
on the numerical keypad. The Vacuum window
will read
[_SEL]
. This places you in select mode.
•
Press the
V
key once and press the
0
key to clear, then
V
key, then
the
0
key to activate the vacuum after being turned off earlier in this
procedure.
Changing the Calibration Number
•
Press the
m
key on the integrator. The Memory window will read
[Ut]
,
the Exposure window will show the existing calibration number for the
top surface of the upper frame at the selected intensity.
•
Press the
Y
key to select frame surface (
[Ut]
,
[Ub]
,
[Lt]
,
[Lb]
).
Remember:
For top frame calibration use
[Ut]
and
[Ub]
and for bottom
frame calibration use
[Lb]
and
[Lt]
. Also, the larger the calibration
number the faster that surface will count and the less accumulated
energy will result on the frame.
•
Enter the new calibration number on the desired surface by pressing
e
key to open the program, then use numerical keypad.
Example:
To change
[Ut]
from 500 to 650 simply press
6,5,0,0
.
•
Press the
e
key to close the program.
•
Press the
0
key twice to return to the operating mode.
