The Highlights

What impressed me most:

VERSATILE CLAMP METER: 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

NON-CONTACT VOLTAGE TESTING: Integrated into the clamp jaw for convenient electrical testing

REVERSE-CONTRAST DISPLAY: High-visibility reverse-contrast LCD ensures improved viewability in all lighting conditions

ACCURATE MEASUREMENTS: Auto-ranging and True Root Mean Squared (TRMS) technology provides precise and accurate measurements

CONVENIENT FEATURES: Test lead holder on the side of the clamp and optional magnetic hanger (Cat. Nos. 69445 or 69417) for hands-free operation

These aren’t just specs – they’re practical advantages that make a difference.
