• Relative Mode for making comparisons

•

to a stored reference value

Auto power off with disable

• Built-in flashlight

• Includes test leads, Type K thermocouple bead

•

probe, 3 AAA batteries and carrying case

1-year warranty

Model CM400:

• Measures 400A True RMS AC Current

Model CM450:

• Measures 400A True RMS AC and DC Current

• DC Zero function

Applications:

Typically when using a multimeter to measure current, you would have to “break the circuit” and place the meter in series with it, so that voltage and current would pass through it. A clamp meter allows you to easily measure current without breaking the circuit by clamping around a single conductor. This saves time and the circuit will not be damaged.
