Klein Tools CL600 Electrical Tester is an automatically ranging true mean squared (TRMS) digital clamp meter measures AC current via the clamp, and measures AC/DC voltage, resistance, continuity, and tests diodes via test-leads. Exclusively designed from the ground up by electricians for electricians. Years of field research, combined with extensive input from electricians across America, inspired the development of meters loaded with innovative, time-saving features.Features Built to withstand a 6.6-foot (2 m) drop Operating altitude to 6,562-Foot (2,000 m) CAT IV 600V, CAT III 1000V, Class 2, Double insulation safety rating Test leads measure AC/DC voltage, resistance, continuity and tests diodes Meets requirements for use in basic and controlled electromagnetic environments like residential, office and light-industrial locations Features Low Battery Indicator Clamp Meter with automatically ranging true mean squared (TRMS) technology for increased accuracy Includes carrying pouch, test leads and batteries Low battery indicator and easily accessible battery compartment Amp Clamp measures AC current 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. 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.
