Data Proof
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.

Model 164B -
Data Proof
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.

OhmRef -
Data Proof
OhmRef provides the power of automation for Standards maintaining statistical control of resistance values in your laboratory. This program controls a Low Thermal Scanner along with other equipment commonly available in Standards Laboratories to compare resistance standards over the range of 100µΩ to 10GΩ . Comparison accuracies arebetter than 1 ppm in the midranges.
