Press the G button twice. This will send the frame into the unit and
•
start the exposure.
After the exposure, retrieve your frame by holding down the S button
•
and press G button. When the frames start to move, release both
buttons.
•
Record the resulting mj reading from the meter.
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 [ U t] , 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.
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 the0 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 [ U t] ,
•
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 ( [ U t] , [ U b] , [ L t] , [ L b] ) .
•
Remember: For top frame calibration use [ U t] and [ U b] and for bottom
frame calibration use [ L b] and [ L t] . 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 [ U t] 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.
