The CD771 is a digital multimeter with an accuracy of 0.5%, and a 4000-count display.
The CD771 digital multimeter is designed for low power circuit analysis, small communication equipment, and home appliances. The device is rated for CAT II (1000 Volts) and CAT III (600 Volts) ranges and is compliant with the IEC61010-1 safety standard.
This digital multimeter has a 4000-count large-size LCD display with backlight functionality. Users can use the data hold button to pause or hold the measurement on the screen and can use the relative function button to store a particular reading for later use. The device also has an Auto-range feature that automatically sets the range of the parameter being measured and makes the device super simple to use.
Users can measure all the basic parameters such as voltage, current, resistance, frequency, capacitance, and continuity test which features a buzzer alarm along with an LED indicator. The device also features a 1.5 Volt battery-check function that allows the user to quickly check the drain of battery power.
The CD771 has a plastic body, with the outer case built with a thermo-elastic elastomer which provides protection against drop shock. To prevent accidents when measuring current, the meter is equipped with a safety cap. It also has a fuse with a breaking capacity of 30 KA to further improve safety.
Meter includes one set of test leads and instruction manual.
