Matching Exposure Surfaces
•
Do a test exposure in the frame being calibrated to the reference frame.
•
Determine the correction necessary to make each surface the same at the
reference surface. If this is done with a step scale the correction is as
follows.

Press
1, 2, 3 t 4
on the numerical keypad. The Vacuum window
will read
[_SEL]
. This places you in select mode.
•
Then press the
m
key and the exposure window will show previous
calibration number. There is a separate number for each intensity. Select
the intensity to be adjusted with the
I
key.
•
Read the current calibration number and multiply it times the correction.
For example if you double the calibration number, the integrator will
count twice as fast consequently the exposure energy will be cut in half.

Then press the
m
key and the exposure window will show previous
calibration number. (for example
[1063.]
).
•
Press the
e
key, the memory window will dim and you will be able to
enter the new calibration number by pressing the new number into the
key pad.
