Quad Scanner
Model 164B - Data Proof (dp)
Data Proof 164B Low Thermal Scanner is designed to allow direct comparisons of four-terminal resistance standards. With two four-terminal output lines and sixteen fourterminal channel inputs, this scanner is an ideal companion for your automatic direct-current-comparator resistance bridge or for a variety of other applications. Make fourterminal resistance comparisons simply by selecting one device on the A channel and another on the B channel. All four connections for both devices in the matrix are
switched. All other devices are left floating.
