Unity LCD Display Digital Multimeter Small multimeter for your day to day needs. If you have basic knowledge about multimeters you can try this small multimeter for basic continuity checks and voltage measurements. Functions: DCV, ACV, DCA. Resistor (ohms). Diode. Buzzer. Transistor (HFE). Temperature. Square wave output. Battery test. Display: 4.75 centimeter length, 15 millimeter high LCD. Operating Instructions: When testing DC voltage, AC voltage, DC current, resistance, diode, buzzer and battery, connect the red test lead to “V 0 mA” jack and black test lead to “COM” jack. When testing the current more than 200mA, connect the red test lead to “‘ OADC” jack and black test lead to number 2022;COM” jack. When testing the temperature, connect the temperature probe to “V, 0, mA” jack or “COM” jack. It can also be connected to the jack specialized for it. When testing the magnifying ratio of the transistor, turn the switch to position and connect the transistor to the eight-hole jack. Square Wave Output: The frequency is 50Hz, the voltage is approximate. 3Vp-p. The output jack is “V, 0, mA” and number 2022. Powered by a 9V battery inside. <Br> PRODUCT DIMENSION: 13X7X2CM (Thickness). Wire Length (Including Pin): 71 centimeters each
