Klein Tools CL445 Clamp Meter is an advanced HVAC clamp meter with automatically ranging true root mean square (TRMS) for maximum accuracy. The meter measures AC current, inrush current, AC/DC voltage, DC microamps, resistance, continuity, frequency, capacitance, temperature, diodes, and more. This Digital Clamp Meter can simultaneously measure current and voltage, has a built-in worklight and comes with right-angle input test leads, push-on alligator clips, K-Type thermocouple, storage pouch, instructional manual, and 3 x AAA batteries.

• Never use the meter on a circuit with voltages that exceed the category based rating of this meter.
• Read, understand and follow all instructions, cautions and warnings attached to and /or packed with all test and measurement devices before each use.
• 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.
• Before each use verify meter operation by measuring a known voltage or current.
• Always adhere to local and national safety codes. Use personal protective equipment to prevent shock and arc blast injury where hazardous live conductors are exposed.
