The Fluke Model 5700A/5720A Series II Callibrator Analysis

As the temperature rise of the heater is converted into a voltage by means of the Seebeck effect which is also temperature-dependent, the mean output voltage will therefore differ when dc and low-frequency ac inputs are applied, thus leading to an ac–dc transfer difference.

3.2 MULTIFUNCTION CALIBRATOR
The Fluke Model 5700A/5720A Series II calibrators are precise instruments that calibrate a wide variety of electrical measuring instruments. These calibrators maintain high accuracy over a wide ambient temperature range, allowing them to test instruments in any environment, eliminating the restrictions to calibrate only in a temperature-controlled standards laboratory.
With a 5700A/5720A Series II, we can calibrate precision multimeters that
In addition to the dependability, simplified calibration, ease-of-use and worldwide support that has made the 5700A number one, the 5720A offers uncertainty specifications that rival anything available today. Customers can get all the performance they need to calibrate their most demanding workload of multimeters up to 8 1/2 digits quickly, easily and reliably. This improvement in performance results from factory testing to even tighter tolerances, and from a variety of hardware and firmware improvements.

5700A Multifunction Calibrator Series II: The world standard
In service since 1988, 5700A Multifunction Calibrator has undergone continuous improvements to become the 5700A Series II, one of the most tested and reliable high precision calibrators Fluke Calibration has ever produced. Considered the calibration standard worldwide, the 5700A delivers high value as well as accuracy covering 5 1/2 to 7 1/2 digit dmms. Plus it offers the same ease of use, low cost of ownership, rugged design, simplified support and confidence building features as the 5720A.
The calibrator takes over the manual metrology functions of establishing ratios and making comparisons, as well as controlling the measurement process.
To assure confidence, the 5700A and 5720A can check themselves against their own internal standards to assure everything is working as expected.
Thousands of 5700A calibrators in service around the world prove Artifact Calibration delivers fast, easy and inexpensive calibration along with the confidence that your instrument is performing as expected between calibrations.
