CM-3

Digital Clamp Meter with True RMS,
Peak Hold and Min/Max

Measures DC/AC Voltage, DC/AC Current, Energy, Resistance

Our compact, low cost Model CM-3 Digital Clamp Meter is ideal for general electrical
testing and troubleshooting. A few applications include HVAC, automotive, electrical/power,
and environmental monitoring uses. The CM-3 measures DC and AC voltage to 600 V, AC
current to 400 A, and resistance to 2000 Ω. The digital clamp meter features data/range
hold and auto range buttons to prevent the screen from updating when gathering values,
as well as a zero function. Additional features include single and three phase energy
measurement, MIN/MAX and average. The 3-3/4 digit backlit LCD features automatic
polarity, overload, low batter y indication and a bar graph. The Model CM-3 is furnished
with red and black test leads, batteries and a carrying case with belt loop.
