Feature: 1. TECHNICAL PARAMETERS: Voltage signal generator voltage output 0‑10V, accuracy for 0.01V, output current <20mA, rotary encoder knob can adjust the output voltage, rotate a circle with 20 pulses 2. ACCURATE MEASUREMENT: The voltage signal generator can accurately measure and adjust small voltages within the rated voltage range, which can be accurate to two decimal places to help you obtain more accurate data for debugging 3. 4 BIT DISPLAY: The adjustable voltage signal generator has a 4 bit LED digital display with clear amplification to accurately monitor the output voltage 4. SAFETY PROTECTION: The output of adjustable signal generator has short circuit protection, the power supply has reverse polarity protection, and the use is safe 5. WIDELY USED: Can be used in electronic equipment and engineering debugging, panel debugging, LED testing, analog transmitter output and other fields. Whether in a factory or a laboratory, equipped with a small versatile adjustable signal generator that you always have a chance to use Specification: Item Type: Voltage Signal Generator Power Supply Voltage: DC 7V-80V, built in reverse protection Output Voltage: 0-3V when the power supply is 7V; When the power supply is greater than 14V, can output 0-10V Power Supply Current: <50mA Output Current: <20mA Package List: 1 x Voltage Signal Generator How To Use 1. Short Press: Switch between coarse or fine adjustment modes. 2. Left and Right Rotation: Adjust the data to decrease or increase, and automatically store the data 3 seconds after stopping the encoder adjustment. When starting up again, directly output the last data. 3. Press and hold for more than 5 seconds to enter the setting interface and display F001. At this time, if you rotate, you can switch between setting items F002, F003; After setting the data, long press the encoder to exit the setting and store the data.
