The CL900 Electrical Tester is an auto-ranging, true root mean square (TRMS) digital clamp meter. It measures AC/DC current via the clamp and measures AC/DC voltage, resistance, continuity, frequency, duty-cycle, capacitance, and tests diodes via test-leads. It features a Low Impedance (LoZ) mode for identifying and eliminating ghost or stray voltages, and has a dedicated mode for capturing Inrush Current. Features: Digital Clamp Meter measures 2000A AC/DC, 1000V AC/DC, 60 Milliohm; Rugged Klein \"TOUGH METER\" industrial design stands up to jobsite demands; built to withstand a 6.6-foot (2m) drop; Automatically ranging True Root Mean Squared (TRMS) measurement technology for accuracy; CAT IV 600V, CAT III 1000V, Class 2, double insulation safety rating; Backlit display for clear visibility in environments with low ambient lighting; Dedicated mode for capturing Inrush Current; Non-contact voltage tester integrated into the clamp; Low impedance (LoZ) mode for identifying and eliminating ghost or stray voltages; Audible continuity, capacitance, diode test, frequency and duty cycle, min/max feature, data hold capability; Test leads measure AC/DC voltage, resistance, continuity, frequency, duty-cycle, capacitance and diodes; Clamp measures AC and DC current; Powers off automatically after 30 minutes of non-use to conserve battery life; Low battery indicator and easily accessible battery compartment; Includes carrying case (instruction manual), straight input test leads, and 2 x AAA batteries; Can be used with Magnetic Hanger Cat.
