The Sanwa CD770 is a sophisticated digital multimeter with a 0.5% accuracy that is intended to measure low-voltage circuits.
The CD770 digital multimeter is designed for basic low-voltage circuit troubleshooting or measuring electric home appliances and has a comprehensive feature set. When measuring in DC mode, this multimeter’s accuracy is 0.5%; when measuring in AC mode, it is 1.2%.
The gadget has a big LCD screen with a 4000 count, as well as an auto-range feature that can also be manually configured via the dial. The multimeter can measure voltage, current, resistance, frequency, and capacitance, and conduct a continuity test with a buzzer alarm, among other fundamental duties.
This multimeter has an all-plastic build, and the outer case is made using a thermoplastic elastomer for protection against drop shocks. The test leads can be attached to the back of the multimeter. It also has a fuse with a breaking capacity of 30 KA to further improve safety.
The meter includes one set of test leads and an instruction manual.
