Data Proof Product Information

160B and 320B Low Thermal Scanner

Data Proof Low Thermal Scanners with extremely low thermal offsets are ideal for automating precision measurements to sub-ppm accuracy. This versatile dual scanner has two pairs of output lines which makes it suitable for a wide variety of uses. It can be used for comparing voltage reference standards, as well as four-terminal measurements on resistance devices. Data Sheet.        Scanner.pdf

160B & 320B Option 3 Guarded Scanner

The 160B Opt.3 and 320B Opt.3 Low Thermal Guarded Scanners are designed to improve accuracy in high resistance measurements. Unguarded, the Data Proof scanners have leakages of about 1012 W which can cause errors of a few tenths of a ppm when measuring 1 MW. Guarding greatly reduces the errors allowing excellent accuracy up to the 1 0GW level. Data Sheet         Guarded.pdf

VoltRef - Voltage Software

VoltRef provides the power of automation for maintaining statistical control of the volt in your laboratory. This program controls a low thermal scanner and voltmeter to compare voltage standards using the process recommended by NIST and other national laboratories.  Data Sheet              VoltRef.pdf

OhmRef - Resistance Software

OhmRef provides the power of automation for 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 100mW to 10GW . Comparison accuracies are better than 1 ppm in the midranges. Data Sheet        OhmRef.pdf
