Klein Tools CL390 Auto-Ranging AC/DC Digital Clamp Meter

The Klein Tools CL390 is an automatically ranging TRMS digital clamp meter that measures AC/DC current up to 400A via the clamp and AC/DC voltage up to 600V. For NCV test use NCV mode with sensing antenna red light and audible signals. The meter also measures resistance frequency DC microamps capacitance duty cycle tests diodes continuity with test leads plus temperature below 446F/ 230C via K-type thermocouple. It offers Range Max/Min Rel/Zero Hold/Brightness and Sel/NCV buttons reverse contrast 4000-count LCD display test lead holder on side of the clamp low battery indicator and auto-power off after 10 minutes of inactivity. The unit can withstand a 6.6-ft drop. It has CAT III 600V Class 2 Double insulation safety rating for use in electromagnetic environments.The CL390 includes the clamp meter test leads with CAT III/CAT IV safety caps thermocouple 3x AAA batteries instructions and carry case.
