Klein Tools CL490 Dual Display Clamp Meter is auto-ranging for precise measurements with a secondary display for easier viewing in tight spaces. The meter reads AC/DC current, voltage, resistance, continuity,frequency, and capacitance; all with True RMS accuracy. It features diode testing and temperature is taken, via thermocouple. There is NCV detection with audio-visual alerts for additional functional applications. To ensure visibility in any lighting, there is a backlit and hi-vis display.
Features
- Dual Display digital clamp meter allows users to see readings in tight space areas
- AC/DC clamp meter with True RMS provides accurate and reliable measurements across various applications
- Measures AC/DC current and NCVT via clamp; AC/DC voltage, resistance, continuity, frequency/duty cycle, DC microamps, diode test and capacitance via test leads; temperature via thermocouple
- Backlit reverse-contrast LCDs for clear data and best view-ability in all environments
- Withstands drops from 6.6 feet (2 m), and includes right-angle input test leads, thermocouple, storage pouch, instruction manual, and 2 x AA batteries
- Ergonomic design provides a comfortable grip, with easy dial adjustment using the thumb
- Non-contact voltage detection is integrated into the clamp jaw, with audible and visual indicators that intensify as the clamp moves closer to the voltage source
- Clamp body includes a side-mounted test lead holder and a back mount that accommodates an optional magnetic hanger (Cat. Nos. 69445 or 69417) for hands-free operation
