A digital multimeter with a 4000-count display and 0.5% accuracy is the CD771.
Small communication devices, home appliances, and low-power circuit analysis are all intended applications for the CD771 digital multimeter. The device complies with the IEC61010-1 safety standard and is rated for CAT II (1000 Volts) and CAT III (600 Volts) ranges.
The 4000-count large-size LCD display on this digital multimeter offers a backlighting feature. Users can utilize the relative function button to save a specific reading for later use and the data hold button to halt or hold the measurement on the screen. The device also features an Auto-range feature that makes it incredibly easy to use by automatically setting the range of the parameter being monitored.
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.
