Star Tester Model 12650-3 Description
This Star Tester is an upgrade of the Model 12650-2 (for 600 Series and other
cameras). The 12650-3 permits testing Spectra System Cameras for seven different
exposure-and timing-related operating characteristics, as well as 600-Series and other
cameras.
Except for a new Horn (P/N 13146) for holding Spectra System Cameras and a few
name changes of Selector Switch positions, the 12650-3 Tester is outwardly identical to
the earlier Model 12650-2 Star Tester.
Model 12650-3 Controls and Indicators
Listed below are the Star Tester 12650 - 3 controls and indicators shown in Figure 3-7.
The integrating light sphere and electronics required to compute and display exposure,
timing and functional characteristics of the camera under test are all housed within the
Tester cabinet.
