Low Thermal Guarded Scanner
160B Opt. 5 & 320B Opt. 5
Data Proof’s Low Thermal Guarded Scanners are designed to improve accuracy in high resistance measurements. Unguarded, the Data Proof scanners have leakages of about 1.5 x 1012 Ω which can cause errors of a few tenths of a ppm when measuring 1 MΩ. Guarding reduces the errors allowing excellent accuracy up to the 1 GΩ level.

Quad Scanner
Model 164B
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 areswitched. All other devices are left floating.
