1、WIDE FUNCTION: The signal generator supports switching more signal modes under different signal types: current signal, voltage signal, XMT passive current signal, pulse signal, resistance, millivolt. 2、REAL TIME AND HISTORICAL DATA: Current and voltage analog simulator aims to automatically display the trend of input and output signals through real time curves. Supports the recording and viewing of a certain amount of historical data. 3、MULTI INTERFACE PORTS: Signal generator uses 4 wiring ports on the top surface, with different colors. Users can choose the correct color cable and corresponding port to start testing. 4、USB RECHARGEABLE AND TFT SCREEN: Built in 3000mAh 3.7V rechargeable battery, the current voltage generator can be full charged in 4 to 6 hours and can work up to 26 hours. Through clear 2.4in TFT backlit screen, you can more understand numerical changes. 5、PROGRAMMABLE OUTPUT: The signal generator has auto output function, and will continuously change according to the set parameters. Widely used for PLC and panel debugging, equipment testing, frequency converters, flow valves, servo motor speed regulation, dimmers, etc. Item Type: Signal Generator Material: ABS Type C Charging Interface: DC5-12V Battery: 1 x 18650 3.7V 3000mAh Lithium Battery Power Supply (Built in) Standby Time: 26 Hours.
