shown in the diagram, removing or interchanging any of the am­ Asplifiers or other instruments is simply a matter of sliding the unit in or out of the mounting rack where contact is made automatically hy plug-in connectors. Screws at the four corners of the panel hold the instrument in place. Other features of this system which add to Sanborn VERSATILITY are the choice of eight paper speeds — 50, 25, 10, 5, 2.5, 1.0, 0.5 and 0.25 m m / s e c , and the use of either 4-, 2-, or 1-channel recording paper. And, of course there are these popular Sanborn advantages: a high torque movement (200,000 dyne cms per cm deflection), direct inkl'ss recording in true rectangular coordinates, and provision for code and time markings. Sanborn Recording Systems may be used to record any one or more of a wide variety of phenomena whose characteristics range from static to 100 cycles per second. If your record­ ing problem is not one which can be solved by standard Sanborn equipment, our engineers will be glad to suggest ways in which modifications of it may suit your requirements.
