Fluke 5720A service manual Introduction, Calibration and Verification

Calibration and Verification 3

Introduction

3-1. Introduction

This chapter gives procedures for 5700A/5720A Series II calibration, verification, acceptance testing, and performance testing. Information here applies to testing the performance of and calibrating a normally operating 5700A/5720A Series II. In case of malfunction, refer to Chapter 5, Troubleshooting, which explains how to use self diagnostic tests to identify a faulty module. Calibration and Performance Testing is presented in the following three parts:

∙Calibration, which is to be done at the beginning of every calibration cycle. This is

the same procedure as in Chapter 7 of the 5700A/5720A Series II Operator Manual. It uses three external standards; 1Ω, 10 kΩ, and 10V dc. The procedure is repeated here for convenience. Also included in this part are procedures for doing Calibration Check and Range Calibration.

∙Full Performance Verification, which is the full verification procedure, recommended every two years. Part of this procedure is Wideband AC Module (Option 5700A-03) flatness calibration, also recommended only every two years.

Optional Tests, which are recommended following repair or for use in acceptance testing. These tests include such checks as load regulation, noise, and distortion. These tests are not required on a routine basis. They are not necessary after a Calibrator passes Full Performance Verification.
