About this Manual This manual provides complete information for installing the calibrator and operating it from the front panel keys and in remote.
Page 23: How To Use This Manual
1-6. Auxiliary Amplifier The Fluke Model 5725A Amplifier is available to extend the high voltage performance and current range of the calibrator: Interface connectors on the calibrator’s rear panel accept cables to directly operate a 5725A.
Page 24: 5725A Amplifier
It maintains full specified stability over a temperature span of 18 to 28 °C. The calibrator uses a 10 V reference standard such as the Fluke 732B in its semi- automated calibration procedure to establish external voltage traceability. Chapter 7...

2. You take a series of readings over a five-day period, and return the results to the Fluke Standards Laboratory. 3. The Fluke Standards Laboratory assigns a value to your 10 V standard relative to the NIST legal volt and sends you a report of calibration.
Page 26: The Components Of The 5700A/5720A Series Ii Calibrator
In the calibrator, one Fluke rms sensor serves as an AC/DC transfer standard to develop gain and flatness correction constants during calibration. The second Fluke rms sensor continuously monitors and corrects output voltage during operation.
Page 27 Figure 1-1 illustrates the time and money that can be saved by using the 5700A/5720A Series II calibration support plan recommended by Fluke. Depending on your policies, you may initially decide to perform calibration verification more often. The calibrator makes this unnecessary and offers you a practical way to collect data unavailable with a traditional calibrator design about performance between calibrations.
Page 28: The Calibration Process
Infrequent verification is done in the traditional way, by comparing selected ac voltage outputs with an external dc voltage standard through an external ac/dc transfer standard. Fluke recommends this is done every two years or as determined by the policy of your organization.
Page 29: Calibration Check
1-20. Developing a Performance History A Fluke specification is a set of performance limits that all products must meet. To maintain consistent quality, Fluke calibrators are specified with enough margin to include temperature, line, and load extremes, plus additional margin for production. This means that a typical 5700A/5720A Series II calibrator in a typical environment operates inside 50 % of specification limits.
Page 30: Specifications
5700A/5720A Series II Operators Manual 1-23. Specifications The 5700A/5720A Series II Calibrators are verified and calibrated at the factory prior to shipment to ensure they meet the accuracy standards required for all certified calibration laboratories. By calibrating to the specifications in this chapter, you can maintain the high performance level throughout the life of your calibrator.

5700A/5720A Series II Operators Manual 4-43. Introduction to Offset, Scale, and Linearity Errors The performance of a DMM or meter can be plotted as a graph of input stimulus and meter reading. For a perfect meter, the graph of the input stimulus would exactly match the graph of the reading.
Page 129: Scale Error
Front Panel Operation Introduction to Offset, Scale, and Linearity Errors 4-45. Scale Error Scale error, sometimes referred to as gain error, occurs when the slope of the meter's response curve deviates from one. A meter with only scale error (no offset or linearity error), will read 0V when 0V is applied, but will read something other than 10V when 10V is applied.
Page 130: Linearity Error
5700A/5720A Series II Operators Manual 4-46. Linearity Error Linearity error occurs when the response curve of a meter deviates from a straight line. This type of error is measured by fixing zero and near-full-scale endpoints on the response curve, drawing a line through the points, then measuring how far the meter response deviates from the straight line at various points.
Page 131: Programming An Offset
Front Panel Operation Programming an Offset 4-48. Programming an Offset You can use o when in the dc voltage or current function any time you want to offset the calibrator’s output by a fixed amount. After you establish an offset, it is subtracted from all later keyboard entries to compensate for a UUT's offset error.
Page 132: Programming A Scale Factor
5700A/5720A Series II Operators Manual 4-49. Programming a Scale Factor You can use the S key in ac and dc voltage and current functions to apply a scale factor to subsequent outputs.

Page 223: Rounding Numeric Entries
Remote Operation 5200A Emulation The voltage range boundaries in the 5700A/5720A Series II are different than those in the 5200A; therefore any discontinuities that can occur at voltage range boundaries will now appear at a different voltage. If you compensate for these discontinuities in your programs, you may wish to determine the new boundaries so that you can modify your programs accordingly.

Each of these are defined in this glossary. flatness A measure of the variation of the actual output an ac voltage source at different frequency points when set to the same nominal output level.
Page 321 Appendices Glossary legal units The highest echelon in a system of units, for example the U.S. National Bureau of Standards volt. life-cycle cost The consideration of all elements contributing to the cost of an instrument throughout its useful life. This includes initial purchase cost, service and maintenance cost, and the cost of support equipment.
Page 322 5700A/5720A Series II Operators Manual minimum use specifications A compilation of specifications that satisfies the calibration requirements of a measurement system or device. The minimum use specifications are usually determined by maintaining a specified test uncertainty ratio between the calibration equipment and the unit under test.
