Description
The Digital Insulation Tester is designed for accurate insulation resistance testing in industrial and electrical applications. It features a high-resolution LCD with 50-segment analog bargraph, making it easy to read at a glance. The tester supports auto-ranging for megaohm measurements, ensuring fast and precise readings up to 4000MΩ.
Equipped with over-range and low battery indicators, the device maintains user safety during tests. It generates a 200mA short-circuit continuity current and auto-discharges for safety after insulation tests. The tester can interface with PCs via RS-232, allowing users to log up to 16,000 measurements. Its robust CAT II 1000V / CAT III 600V rating ensures compliance with international safety standards (IEC 61557), making it suitable for use in industrial, commercial, and maintenance environments.
