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.
