Between 4 and 10 reference modules

Each Nanoscan system consists of one or more Model 7000 solid-state zener reference modules that plug into a mainframe chassis. The 10-Volt ouputs from these modules are routed via an analog signal backplane to the Nanoscan module where they are averaged to produce an ultra low-noise hardware Average 10 Volt output.

High sensitivity null detector

The Nanoscan module also contains a high-sensitivity (0.01ppm resolution) null detector that compares individual 10-Volt reference outputs with the Average output, enabling you to verify the stability of each reference to a very high confidence level. Individual references can also be switched in and out of the hardware average to evaluate their overall contribution.

Simple integration of external reference standards

In addition to intercomparing individual internalreferences to the system average, the null detector can also be used to measure external reference standard, providing an easy method of importing or exporting traceability from the Nanoscan system.

10-Volt Average, Buffered 10-Volt Average and Average 1.018-Volt Outputs

The Nanoscan module also generates a buffered 10V output to drive resistive loads such as Kelvin Varley dividers, and a 1.018V output for comparison with Weston cells.

Automatic intercomparison using 7050 volt maintenance software

Although the Nanoscan can be driven manually via its front panel controls, the full benefits of process automation is achieved when you use it with the 7050 Volt Maintenance Software. This software, which runs under WindowsTM95 or NT, enables you to initiate scan sequences and log all the results into an ExcelTM spreadsheet for later analysis.
