NOTE : The foregoing tests assume that when the camera is operated, the viewing mirror (Fresnel carrier) reaches the correct attitude during the exposure cycle. If the lens has been correctly collimated, the only check possible of actual picture definition is to expose film.
3. Comprehensive Testers (Figure 3-6 and 3-7)
There are two models of Comprehansive Testers available for
interrelated units : the Comparalumen calibrated ligh source, the electronics module, and the mounting horn or holding fixture. The purpose of both tester models is to check the dynamic operating functions of the camera ( A detailed description of the later tester is available in a technical manual titled «Model B camea tester». This section will deal only with the operating instructions for the tester.)

Before testing the camera, perform the following
(1)Calibrate the tester daily. Record the calibration reading in a log. (If the test equipment is suspected of poor performance, calibrate more frequently and repair if necessary.)
(2)Remove the front cover from the camera
