Chauvin Arnoux CA6543 – 1 kV High-Performance Insulation & Continuity Tester

Overview

The Chauvin Arnoux CA6543 is a highly capable, industrial-grade insulation and continuity tester designed for engineers, maintenance teams, and procurement professionals who need reliable, accurate and versatile electrical insulation diagnostics. Operating over test voltages from 50 V to 1,000 V DC, it handles insulation resistance up to 4 TΩ, providing rich measurement features, advanced safety protections, and rugged construction suited for field use. With built-in memory, programmable alarms, remote communication capability, and automatic computation of key insulation quality metrics (DAR, PI), it stands as a benchmark for serious insulation testing.

Key Features

• Wide range of insulation test voltages: 50, 100, 250, 500, 1,000 V DC

• Insulation resistance up to 4 TΩ over five ranges

• Automatic computation of DAR (Dielectric Absorption Ratio) & PI (Polarization Index), for assessing insulation quality and ageing

• Programmable test durations; ability to plot R(t) curve (resistance vs. time)

• Automatic voltage indication before/after measurement; protection if object under test has voltage >25V

• Continuity measurement: 0.01 Ω to 40 Ω with audible beep and lead (cable) compensation

• Resistance mode: 0.01 Ω to 400 kΩ

• Automatic capacitance measurement after each insulation test: 0.005 – 4.999 µF

• Large backlit LCD screen with digital readout and bar-graph display for clear visualization

• “SMOOTH” function: smoothing of displayed values for stable readings

• Programmable alarms and ability to lock test voltage setting

• RS-232 bidirectional interface; PC communication (e.g. with DataView® software) for remote control & data download

• Rechargeable NiMH battery with internal charger; long battery life in field conditions

• Meets safety standards: IEC 61010 CAT III 600 V and IEC 61557

Applications

• Preventive maintenance of electrical installations, motors, generators, windings, transformers

• Asset condition monitoring to detect insulation degradation over time (using DAR/PI)

• Insulation testing of cables, switchgear, HV connectors, outdoor equipment

• Safety inspections in industrial facilities, utility networks, substations

• Research & development laboratories where high range insulation/resistance testing is required

• Field service where rugged, battery-powered, portable instrument is needed
