CD771 Digital Multimeter: Precision, Safety, and Versatility for Every Task

The CD771 Digital Multimeter is engineered for both precision and ease of use, making it an indispensable tool for professionals and DIY enthusiasts alike. With a robust 0.5% accuracy and a clear, backlit 4000-count display, this multimeter ensures you get reliable readings in any environment.

Designed for Diverse Applications: Whether you're troubleshooting low-power circuits, working with small communication equipment, or handling home appliance repairs, the CD771 is built to perform. Its versatile capabilities cater to a wide range of electrical and electronic tasks.

Uncompromising Safety: Your safety is paramount. The CD771 is rated for CAT II (1000 Volts) and CAT III (600 Volts), adhering strictly to the IEC61010-1 safety standard. This means enhanced protection against transient overvoltages, providing peace of mind during high-energy measurements. Further safeguarding against accidents, the meter features a safety cap for current measurements and a high-capacity 30kA fuse.

Intuitive Features for Effortless Operation:

• 4000-Count Backlit LCD: A large, crisp display with backlight ensures measurements are easy to read, even in dimly lit conditions.
• Auto-Range Functionality: No more guessing! The CD771 automatically selects the optimal range for the parameter being measured, simplifying operation and preventing potential errors.
• Data Hold: Conveniently freeze your readings on the screen for easy recording or analysis.
• Relative Function: Store a reference reading and measure subsequent values relative to it, perfect for quickly assessing changes.
• 1.5V Battery Check: Quickly assess the health of common 1.5V batteries.
• Auto Power Save: Extends battery life by automatically powering down after approximately 30 minutes of inactivity.

Comprehensive Measurement Capabilities: The CD771 measures all essential electrical parameters with high accuracy:

• Voltage (DCV & ACV)
• Current (DCA & ACA)
• Resistance
• Frequency
• Capacitance
• Continuity: Features an audible buzzer and a red LED indicator for quick circuit checks.
• Diode Test

Built to Last: Durability is key. The CD771 boasts a rugged plastic body encased in a thermo-elastic elastomer outer shell. This double molding design provides superior protection against drops and impacts, making it ideal for tough work environments.
