Designed to accurately measure current, current leaks (parasitic draws down to 1mA) and electrical loads from 1mA to 100 amp AC/DC and voltages from 0 to 600 AC/DC. The small diameter (½ inch or 13mm) and narrow jaw makes it ideal for use in confined spaces and on small gauge wires. Other fea tures include resistance measurement functions, audible continuity test, display hold and peak detector. Large 4 digit LCD display. Clamp opens up to ½" (12.5 mm). Operates with one rotary switch. One touch auto zero. Test leads and batteries included. Includes soft shell carrying case
