Full calibration of an 11302 requires the use of the [[TEKCATS]] software. | Full calibration of an 11302 requires the use of the [[TEKCATS]] software. | ||
The 11301 and 11302 make use of a [[Patent_US_4677340A|patented]] system for automatically calibrating all the way to the graticule | |||
(i.e., including CRT deflection sensitivity) by optically sensing the position of the beam with respect to the graticule | |||
and applying any necessary correction factors. This is discussed in the patent and also on page 9 of the Handshake article linked | |||
below which states: | |||
<blockquote> | |||
Optical sensors on the CRT bezel sense when the beam crosses the graticule lines to factor this information into the auto cal control signals. As a result, accuracy of the 11300-Series is controlled from the plug-in input connector to the CRT graticule without operator intervention. | |||
