OPERATOR SAFETY SUMMARY WARNING HIGH VOLTAGE is used in the operation of this equipment LETHAL VOLTAGE may be present on the terminals, observe all safety precautions! To avoid electrical shock hazard, the operator should not electrically contact the output hi or sense hi binding posts. During operation, lethal voltages of up to 1100V ac or dc may be present on these terminals. Whenever the nature of the operation permits, keep one hand away from equipment to reduce the hazard of current flowing

Introduction and Specifications Introduction 1 Introduction 1-1. The Fluke 5725A Amplifier enhances the 5700A Calibrator in the ac voltage, ac current, and dc current functions. The 5725A operates under complete control of the 5700A through an interface cable supplied with the 5725A. A diagram in the specifications tables at the end of this section illustrates the extended ac volt-hertz product achieved by using a 5725A. Increased ac voltage load limits allow using the 5700A Calibrator in system

5725A Instruction Manual Where to Go From Here 1-2. This manual is the operator and service manual for the 5725A. However, because the 5725A operates under the control of the 5700A Calibrator, most operating instructions for the 5725A are in the 5700A manuals. Topics such as selecting output values, connecting to a UUT (Unit Under Test), and self calibration are covered in the 5700A Operator Manual. The list below gives some specific pointers, and the text further on describes how to use all the
