400A, HVAC Digital Clamp Meter, AC Auto-Ranging. Clamp Meter measures AC 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. Non-contact voltage tester integrated into the clamp jaw. Backlit LCD for ease of viewing in low light. Automatically ranging True Root Mean Squared (TRMS) measurement technology for accuracy. Test lead holder on side of clamp and optional magnetic hanger for meter (Cat. Nos. 69445 or 69417) for hands free operation. Measures temperature with a K-Type thermocouple probe. Auto-Range, Data Hold, and Max/Min value. 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.
