Klein Tools CL700 Electrical Tester is an automatically ranging true root mean squared (TRMS) digital clamp meter that measures AC current via the clamp, and measures AC/DC voltage, resistance, continuity, frequency, capacitance, and tests diodes via test-leads, and temperature via a thermocouple probe. It also features a Low Impedance (LoZ) mode for identifying and eliminating ghost or stray voltages. Klein Tools' Test and Measurement product line was 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.Warnings Before each use verify meter operation by measuring a known voltage or current. Do not attempt to measure resistance or continuity on live circuits. 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. Read, understand and follow all instructions, cautions and warnings attached to and /or packed with all test and measurement devices before each use.
