Test Procedure
1. Push the Reset button on the Tester, then depress the Shutter Button. Disregard the
meter reading (this sets up Tester circuitry).
2. Press the Shutter Button again and watch the Timing Meter carefully. Note the
reading that remains constant for two seconds. Compare this reading to the
Specification.
3. If the reading is not within spec, adjust the blade speed (page 3-30) and retest the
camera.
4. If the adjustment did not bring the Blade Speed within specification, repair or replace
the Shutter Assembly and retest.
5. If Blade Speed is now within specification but Strobe Exposure is still out of spec,
replace the Exposure Flex and retest.
