Feature: 1. Multiple Signal Modes: The signal source generator is available in multiple signal modes, mA current signal (0 to 24 mA, accuracy 0.01mA), V voltage signal (0 to 24V, accuracy 0.01V), XMT passive current signal (0 to 24mA, accuracy 0.01mA), pulse signal (frequency output 0 to 9999Hz, accuracy 5 bits). 2. Presettable Design: Input signals can be converted to output signals between different physical quantities Support 4 groups of commonly applied signal values that can be preset for quick and easy output adjustment. 3. Display Curve Automatic Adjustment: The signal source generator can also automatically adjust the display curve within the range of maximum and minimum values within a certain timing period. 4. Long Working: Signal source generator can work for up to 26 hours on a full charge. The clear TFT screen display can show the trend of input and output signal changes by curves and setting the sampling timing of the curve. 5. Automatic Output Mode: The signal source generator has automatic output function, which can change the size continuously according to the set parameters, and three modes of monotonic rising, monotonic falling and cyclic can be selected. 6. Use Scenarios: Widely applied to PLC and panel debugging, device testing, inverter, flowing valve, servo motor speed control, dimming, etc. Specification: Item Type: Multifunctional Signal Source Generator Material: ABS Model: SG 003A Accuracy Error: ± (0.1%+0.005) Current Measurement Range: 0-24mA Display Specifications: 2.4 inch backlit color screen Internal Impedance: 750Ω Frequency: 0-9999Hz Charging Interface: Type C Power Supply: Built in rechargeable lithium ion battery 3.7V Capacity: 3000mah (shipping with built in battery) Suitable for: PLC system debugging, servo drive machine speed regulation, valve positioner adjustment, instrument test calibration, inverter detection .
