Measurement Range
Voltage Detection: The tester is designed to detect the presence of electrical voltage within a wide range, generally cited as 50V AC up to 500V AC. Other sources specify a range of 90V AC to 500V AC or 60V AC to 500V AC., Mechanism: It uses a neon lamp indicator that glows when voltage is present, clearly identifying live lines., Safety and Use: The tool features a fully insulated, shockproof design for user safety and is suitable for general electrical troubleshooting and maintenance tasks.
