Setup And Pre-Test Checks - Polaroid ProCam Repair Manual

Setup and Pre-test Checks

1. Install the Tester on a level surface with clear area around the Tester to
allow sufficient air flow for cooling.
2. Locate the Tester (Figure 2-2) on a bench or table so that when the
ProCam on its Horn is placed on the top of the Tester, the ProCam lens
will be exactly 4.5 feet (135 cm) from a graywall target. Also, be sure that
the front of the ProCam is parallel to the graywall (or the long axis of the
ProCam, front to back, is at right angles to the graywall).
3. Be sure that the area between the ProCam and the graywall, for a width of
approximately four (4) feet (or what can be seen in the ProCam
viewfinder), is clear of any objects. This will prevent erroneous readings
caused by reflections from the sonar side lobes of the ProCam.
