Klein® Tools CL380 | AC/DC Digital Clamp Meter, 400A Auto-Ranging

SKU: TO-KCL380 Categories: , ,

Klein 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.


  • Measures both AC/DC current via the clamp
  • Non-contact voltage tester integrated into the clamp jaw
  • High-visibility reverse contrast LCD display for improved viewability in all ambient lighting conditions
  • Automatically ranging True Root Mean Squared (TRMS) measurement technology for accuracy
  • Measures AC/DC voltage, DC micro-Amp current, resistance, continuity, frequency, duty-cycle, capacitance and tests diodes via the test leads
  • Measures temperature with a K-Type thermocouple probe
  • Max/min, Rel/zero and data hold capability
  • Auto power off after five minutes to conserve battery life
  • Low battery indicator and easily accessible battery compartment
  • Built to withstand a 6.6 foot (2m) drop
  • Includes a carrying case, test leads, thermocouple probe, instruction manual and 3 x AAA batteries
  • CAT III 600V, Class 2, Double insulation safety rating
  • Meets requirements for use in basic and controlled electromagnetic environments like residential, office and light-industrial locations
