The Klein Tools CL800 electrical tester is an automatically ranging True RMS (TRMS) digital clamp meter that measures AC or 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.
Options include:
Klein CL600 – 2707987
Klein CL700 – 2707988
Klein CL800 – 2707989

True RMS - it accurately measures AC current even with distorted waveforms
Auto-ranging: It automatically selects the correct measurement range, simplifying operation.
Extensive measurements: It tackles all the basics from AC/DC voltage, resistance, and continuity to more advanced readings like frequency, capacitance, and diode testing.
