F. Camera Adjustments (correcting out-of-spec test results)
This section describes adjustments which can be made to correct readings which are
out-of-specification on the Star Tester #12650-2.
Refer to the Specification Chart to determine acceptable readings for each of the
tests listed below.

1. Flash Timing

a. Remove the Front Plate/Lens Panel from the apron (Fig. 8).
b. Using tweezers, grasp the end of the opening blade spring.
c. Move the opening blade spring up in the rack to increase the reading or down in the
rack to decrease the reading (Fig. 9).
d. Reassemble and retest the camera. Readjust the opening blade spring if necessary. If
the adjustment cannot bring the reading into specification, replace the opening blade
spring and repeat step 3.
e. If the reading is still out-of-specification, disassemble the camera to the shutter level.
Examine the shutter area for loose or misplaced parts, binding blades, etc. Correct
any problems found and reassemble and retest the camera. Readjust the opening
blade spring if necessary.
