NF-5330A is a pocket type 3 5 / 6-digit pocket type real effective value intelligent scanning digital instrument; the series is triple display: main display, secondary display, analog bar. Except for the display frequency of AC voltage measurement sub display, other function sub display is normal temperature. In the process of using, users can operate continuously. There is no need to turn the dial to select the function. The meter will automatically recognize and measure based on the input AC or DC current/resistance. It has stable performance, high precision, high reliability, clear reading and overload protection. Driven by AAA 1.5V battery, the instrument adopts large screen LCD display and adopts boost power supply. Even at the edge of 2.3V low battery, it can ensure the high brightness of backlight and flashlight. The meter is easy to carry and is very popular among users. This series of instruments can manually switch and measure DC voltage and AC voltage, capacitance, NDV, diode, continuity test, live wire judgment and true RMS. It is a superior tool and an ideal tool for laboratories, factories, radio enthusiasts and families.
