Fluke Calibration 5720A-03 Multifunction Calibrator

Overview

The Fluke Calibration 5720A-03 is a five-function electrical calibrator designed to address the full electrical calibration workload. It sources direct and alternating voltage and current, and resistance with specifications optimized for precision calibration of high-performance test equipment. The model 5720A-03 includes a wideband voltage option (03) that extends overall AC bandwidth to 10 Hz to 30 MHz, enabling calibration of RF voltmeters and high-frequency measurement equipment.

Key Features

• DC voltage to 1100 V
• AC voltage to 1100 V, output available from 10 Hz to 1.2 MHz (extended to 30 MHz with option 03)
• AC and DC current to 2.2 A, output available from 10 Hz to 10 kHz
• Resistance measurement and sourcing capabilities
• Internal environmentally-controlled references for stable performance over wide ambient temperature range
• Automatic meter error calculation with display of linearity, offset, and scale errors
• Programmable entry limits to restrict accessible output levels and prevent equipment damage
• Offset and scaling modes for simplified linearity testing of multimeters
• Variable phase reference signal output and phase-lock input
• Keys for multiplying and dividing output value by 10

Applications

• Calibration of RF voltmeters and high-frequency measurement equipment
• Precision calibration of digital multimeters and electrical test instruments
