TECHNICAL PRINCIPLES OF OPERATION.
3-3.1.
General.
a.
The light integrating exposure control instrument is a precision integrated process control unit. The multicolor
phototube provides calibrated time (seconds) reference to the instrument for setting exposure times.
b.
The exposure control instrument automatically computes copy range exposure time for highlight densities within
the range of .00 through .30. The instrument provides electrical power to the flash, shutter, and lamps circuits at required
times.
c.
The exposure control instrument can be operated remotely with the addition of the remote control station.
