The General Resistance D A S is a versatile laboratory Instrument that provides high precision and stability In a compact portable unit. It Is so designed and constructed as to be essentially Independent of ambient temperature and loading within the instrument ratings. The DAS has the following basic functional modules? 1 * A chopper-stabilized operational Amplifier. 2. A highly stable reference source. 3. A Kelvin-Varley potential divider. The D A S is contained in a package whose envelope Is: Series 40 & 50: 6-7/16" h x 6 " w x 7" d Series 60, 70 & 80? 7" h x 8" w x 10-5/16" d The D A S 50 and 80 have built-in constant-current operation while the DAS 40, 60, and 70 can be used with an inexpensive adaptor to provide constant-current operation. Remote sensing terminals are provided to furnish the calibrated voltage at locations distant from the Dial-A-Source output terminals. The remote sensing capability automatically compensates for the voltage drop in the connecting cables.
