The Extech 380942 is a 30-amp tiny AC/DC clamp meter. The clamp meter boasts an impressive 0.1mA resolution (AC), extremely low-current sensitivity, and a small diameter jaw designed to reach into tight spaces. The 30 Amp range with 0.1mA (AC) and 1mA (DC) precision is ideal for detecting problems where typical clamp meters would miss very small current variations. This tiny clamp meter can be used to diagnose plant maintenance, electrical, HVAC, and telecom issues, as well as domestic electrical, fleet maintenance, marine, and motorbike repairs. This CAT III True RMS tiny clamp meter includes test leads, two AA batteries, a protective carrying bag, and a user manual.
