Have questions? We're here to help!

Designed for in home repair and electrical testing applications, the AM-420 Digital Multimeter accurately measures voltage in receptacles, switches, extension cords and light fixtures. Use the continuity function to easily troubleshoot light bulbs and fuses. This compact tools is designed for in-home repair and electrical testing applications, including measuring presence of voltage in electrical sockets, extension cords, batteries and other electrical circuits up to 250 V. It is a must have tool for residential projects including installation, troubleshooting or repair of light fixtures, fans or appliances. DC ranges of voltage and current are included to help with automotive diagnostics of electrical systems. The battery test feature checks the amount of charge remaining in standard 1.5 V and 9 V batteries.

The AM-420 comes with test leads (installed), one (1) 9 V alkaline battery (installed) and a user's manual.
