|New Models 160B and 320B
Your faithful old 160A and 320A scanners have worked hard over the past 10 to 20 years. Perhaps it's time to think about their retirement and replacing them with our new line of Data Proof Low Thermal Scanners. For a limited time, receive up to a 20% discount on the purchase of a new 160B or 320B Low Thermal Scanner with your trade in. (US customers only) TradeIn.PDF

|Driver for LabVIEW
A driver for for all Data Proof Scanners is now available for National Instrument's LabVIEW software. Customers download the following file for the driver and documentation. LabVIEW Driver.zip
|VoltRef Version 7 upgrade:
Upgrade to version 7 of VoltRef for Windowsâ to maintain statistical control of your volt. Version 7 expands the uncertainty analysis, enables saving and merging reports as text files, provides for 10 digit serial numbers and more. See the upgrade announcement for more details or ask for a product demo or a free 30 day trial.
VoltRef for Windows creates a test design, controls your Low Thermal Scanner and voltmeter and begins taking measurements with a few clicks of a mouse. When VoltRef completes the test, your report is displayed and the results are ready to be saved. With a few more clicks of your mouse youve created charts of your historical data for statistical analysis.
VoltRef continues to offer the popular features that made VRMP the industry standard for automating precision voltage measurements in the laboratory. VoltRef continues to offer the popular delayed start feature for setting measurement up to measurement up to run at a future time or to set up a measurement schedule. Slope correction for predicted drift of references and the capability to make 10-to-1 volt, or 1-to-10 volt comparisons are also available.
VoltRef is even easier to operate with additional prompts and help screens. Historical data can now be both imported and exported to spreadsheets as .csv files. A selection of measurement designs have been added including the favored-cell, ring and NIST recommended designs.
Order VoltRef-UPG6 for upgrades from version 6.x; and VoltRef-UPG to upgrade from all earlier versions.
|New High Ohm System for OhmRef:
A fourth method useful for high resistance measurements is now available in the OhmRef resistance software. By using a guarded scanner and two sources to form a guarded resistance bridge, measurements from 100KW to 10GW can be made with excellent accuracy.

|New Scanner Interface Board:
Scanners purchased prior to early 1997 with serial numbers below 700 may experience a timing problems when controlled by Pentium computers with processors above 70Mhz. This problem may appear like an intermittent problem where multiple commands are rapidly sent to the scanner only one of the commands will be received. (In some cases the scanner will fail to respond at all.)
This problem can be solved by purchasing a new later revision of the scanner interface board part number 320-007D. This new board is a direct replacement and you can be easily changed in your laboratory. To replace the board, simply removing the top cover and pull out the old 320-007A board and replace it with the new board. Contact Data Proof for current price and availability of the new board.
|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
