Key Features:

• True RMS Measurements: Ensures accurate readings of AC voltage and current, even for distorted waveforms, in demanding applications like HVAC and industrial settings.
• Non-Contact Voltage Detection (NCV): Quickly and safely detects the presence of AC voltage without physical contact, enhancing user safety.
• Low Impedance Mode (LoZ): Eliminates false readings caused by "ghost voltages" in high-impedance circuits, providing accurate measurements in challenging environments.
• Low Pass Filter (LPF): Attenuates high-frequency noise for accurate readings in noisy electrical environments.
• Large, Backlit LCD Display: Ensures easy readability in various lighting conditions, improving user experience.
• Data Hold Function: Freezes readings on the display for easy recording and analysis.
• Auto Power Off: Conserves battery life by automatically shutting down the meter after a period of inactivity.
• Rugged and Durable Design: Built to withstand drops and impacts, making it suitable for demanding field use.
• Comprehensive Measurement Capabilities: Measures AC/DC voltage, AC/DC current, resistance, capacitance, frequency, duty cycle, and temperature.
