Klein Tools CL390 is an automatically ranging true root mean squared (TRMS) digital clamp meter. It measures AC/DC current and NCVT via the clamp, AC/DC voltage, DC microamps, resistance, continuity, frequency, capacitance, and diodes via test leads, and temperature via a thermocouple probe. It features a high visibility, reverse contrast LCD display that optimizes view ability both in dark or bright ambient lighting. Test lead holder on side of clamp and optional magnetic hanger for meter (Cat. Nos. 69445 or 69417) for hands free operation. Non-contact voltage tester integrated into the clamp jaw. High-visibility reverse contrast LCD display for improved view ability in all ambient lighting conditions. Automatically ranging True Root Mean Squared (TRMS) measurement technology for accuracy. Measures AC/DC current and NCVT via clamp and AC/DC voltage, resistance, frequency, DC microamps, capacitance, duty cycle, diode test, and continuity via test-leads, and temperature with thermocouple. Measures temperature with a K-Type thermocouple probe. Max/Min, Rel/Zero and Data Hold capability. Auto-power off after 10 minutes to conserve battery life. Includes a carrying case, test leads with CAT III/CAT IV safety caps, thermocouple, instructions, and 3 x AAA batteries. Low battery indicator and easily accessible battery compartment. Built to withstand a 6.6-Foot (2 m) drop. CAT III 600V, Class 2, Double insulation safety rating. Meets requirements for use in basic and controlled electromagnetic environments like residential, office and light-industrial locations.
