This pen type multimeter with stable performance, high precision, low power consumption. It can measure AC/DC voltage, AC/DC current, resistance, diode and continuity; with non-contract voltage detection function, timely remind users to pay attention to the operation safety and allow users to use more safely and assuredly. Features: Pen multimeter design auto range and manual range. Can measure DC voltage, AC voltage, DC current, AC current, resistance, diode and continuity. With non-contract voltage detection, timely remind users to pay attention to the operation safety and allow users to use more safely and assuredly. Data hold function, LCD display with backlight. Use the PTC protection circuit for Resistance, continuity sensor confirms that the circuit conducts electricity. If pen multimeter measured resistance less than 50, the buzzer will sound, tell you the circuit issue quickly. All in one design, easy to use, weighs light, portable bag can carry, suitable for home, factories, schools, cars and other electrical tester and maintenance.
