The CL220 measures AC current and NCVT via clamp and AC/DC voltage, resistance, and continuity via test-leads, and temperature with thermocouple. The meter features automatically ranging True Root Mean Squared (TRMS) measurement technology for accuracy. Additionally, a backlit LCD makes viewing in low light easy.Warnings Do not attempt to measure resistance or continuity on live circuits. Read, understand and follow all instructions, cautions and warnings attached to and /or packed with all test and measurement devices before each use. Before each use verify meter operation by measuring a known voltage or current. Usage of this meter in any way other than that specified by the manufacturer can impair safe operation, resulting in severe injury or death. Do not use the meter during electrical storms or in wet weather, and do not use the meter or test leads if they appear to be damaged. Features Backlit LCD for ease of viewing in low light Meets requirements for use in basic and controlled electromagnetic environments like residential, office and light-industrial locations Includes a carrying case, test leads with CAT III/CAT IV safety caps, thermocouple, instructions, and 3 x AAA batteries Auto-power off after 10 minutes to conserve battery life Clamp Meter measures AC current and NCVT via clamp and AC/DC voltage, resistance, and continuity via test-leads, and temperature with thermocouple Non-contact voltage tester integrated into the clamp jaw Auto-Range, Hold, Data Hold, and Max value Low battery indicator and easily accessible battery compartment Measures temperature with a K-Type thermocouple probe Automatically ranging True Root Mean Squared (TRMS) measurement technology for accuracy Built to withstand a 6.6-Foot (2 m) drop CAT III 600V, Class 2, Double insulation safety rating Test lead holder on side of clamp and optional magnetic hanger for meter (Cat.
