AC/DC Digital Clamp Meter - 400A Auto-RangingKlein Tools CL380 is an automatically ranging true root mean squared (TRMS) digital clamp meter that measures AC/DC current via the clamp, AC/DC voltage, DC microamps, resistance, continuity, frequency, capacitance, and diodes via test leads, and temperature via a thermocouple probe. It includes a non-contact voltage tester integrated into the clamp, and features a high visibility, reverse contrast LCD display that optimizes viewability both in dark or bright ambient lighting. Features:Measures both AC/DC current via the clampNon-contact voltage tester integrated into the clamp jawHigh-visibility reverse contrast LCD display for improved viewability in all ambient lighting conditionsAutomatically ranging True Root Mean Squared (TRMS) measurement technology for accuracyMeasures AC/DC voltage, DC micro-Amp current, resistance, continuity, frequency, duty-cycle, capacitance and tests diodes via the test leadsMeasures temperature with a K-Type thermocouple probeMax/min, Rel/zero and data hold capabilityAuto power off after five minutes to conserve battery lifeLow battery indicator and easily accessible battery compartmentBuilt to withstand a 6.6 foot (2m) dropIncludes a carrying case, test leads, thermocouple probe, instruction manual and 3 x AAA batteriesCAT III 600V, Class 2, Double insulation safety ratingMeets requirements for use in basic and controlled electromagnetic environments like residential, office and light-industrial locationsWARNING: This product can expose you to chemicals which are known to the State of California to cause cancer, birth defects or other reproductive harm.
