XR 3000 Adjustment Features
A. Introduction
The XR 3000 is fitted with an XRTV Zoom X-Ray camera. The zoom camera
magnification can be varied from 7x to 40x. The memory button can be used
to store a magnification setting and to quickly return to that setting.
The XRTV Zoom X-Ray camera utilizes the latest servo -control and
microprocessor technologies to produce sharp, high resolution images at any
magnification. The camera automatically monitors and adjusts the focus and
exposure parameters.
B. Camera Operation
The camera is controlled through the button and two switches mounted on the
XR 3000 control panel. See Figure 3.

When the power is turned on, the camera automatically sets itself to 14X
magnification. This is the magnification setting that is stored in memory when
the unit leaves the factory.
The camera operates in either the ZOOM control mode or the GAIN control
mode; set by the rocker switch on the control box panel. See Figure 3. To
adjust the image magnification, place the control switch in the ZOOM setting.
The camera magnification is controlled by the +/- rocker switch. Press the
rocker in the + direction to increase the magnification. Press the rocker in the
- direction to decrease the magnification.
