Product Overview
(Overview of Core Selling Points)
The 790A series high-end digital multimeter integrates Auto-Select and Auto-Ranging technologies, making it an all-in-one professional diagnostic tool designed for engineers, electricians, and electronics enthusiasts. Equipped with advanced features such as a high-definition VA color display, Non-Contact Voltage Detection (NCV), Live wire detection, and Bluetooth data logging (optional model), it delivers a safe, accurate, and convenient measuring experience.
【Core Features】
? Fully Automatic Smart Mode: Powers on directly into "Auto" mode, automatically identifying and switching between DC/AC voltage, resistance, continuity, and other measurement functions—significantly improving工作效率.
? True RMS Measurement: Accurately measures AC voltage and current in non-sinusoidal or nonlinear loads for more reliable readings.
? HD VA Color Display: 6000-count large main display + secondary parameter display + analog bar graph + function icons—clear and intuitive reading.
? Non-Contact Voltage Detection (NCV): Safely detects AC voltage from 90V to 1000V without touching wires, with audible and visual alerts.
? Live Wire Detection: Accurately identifies live wires in sockets using test leads, preventing misoperation.
? Comprehensive Measurement Capabilities: Supports DC/AC voltage, DC/AC current, resistance, capacitance, frequency, duty cycle, temperature (K-type thermocouple), diode test, and continuity test.
? User-Friendly Design: Built-in flashlight, data hold (HOLD), relative value measurement (REL), max/min recording, and auto power-off (15 minutes).
