True RMS: The RMS/DC transform ensures accurate measurements by minimizing the impact of voltage waveform distortion and features a self-calibrating chip. NCV Test (V~Alert): Non-contact voltage detection allows users to detect voltage without direct contact with wires for added safety. Temperature Measurement: Built-in temperature measurement function suitable for HVAC system inspections with Celsius/Fahrenheit selection. Automatic Backlight: Auto-illuminating display enables operation in low-light or dark environments. Functions: AC/DC voltage, AC/DC current, resistance, diode test, continuity, NCV, True RMS, temperature, frequency/duty cycle, capacitance, auto power off, data hold, backlight, and more.
