The TRIPLETT Model CM1000 True RMS Clampmeter can measure AC current up to 1000 Amp without breaking the circuit by clamping around a single conductor. This saves time and the circuit will not be damaged. True RMS provides better accuracy when measuring non-sinusoidal or noisy waveforms. Additional measurements include Resistance， Capacitance， Frequency， Temperature， Diode Test and Continuity. Measurements can read on the 6000-count backlit LCD. It has an Inrush current function that captures the instantaneous surge (inrush) current when power equipment is turned on. Features include: Lo Z (impedance) mode for identifying ghost voltages， Low Pass Filter (LPF) for filtering frequency and harmonic interference when measuring variable frequency drives， Peak voltage capture with minimum/maximum， NCV Detector with LED， Relative/DC zero function， Auto power off and a built-in flashlight. Data Hold freezes the display for easy viewing. CAT IV-600-Volt safety category. cETLus Listed. Includes 3 AAA batteries， test leads， Type K thermocouple probe and carrying case. 1-year warranty.
