1、4 Digit Display: The signal generator has 4 different types of digital display with 2 decimal points. You can press the mode button to switch the display mode between voltage and current, or you can switch the 0 to 100 percent or 0‑50Hz display according to the instructions. 2、Output Range: The output range is passive or active 0‑20mA, 0‑10V, and the voltage output can be accurate to 0.00V. The output range and accuracy can be programmed and adjusted. 3、Safe to Use: The output has short circuit protection, and the power supply has reverse connection protection, which is safe to use. Users can set 9 fast signal output points, which is more convenient for debugging. 4、Multiple Power Supply Modes: The function generator can supply power through various modes, such as micro USB 5V and external power supply DC 15‑30V. Each mode can make the signal generator work. 5、Widely Applicable: The signal generator can be used for PLC and panel debugging, equipment testing, frequency converter, flow valve, servo motor speed regulation, dimming, etc. And the fenerator is small and portable. 1 x Signal Generator Item Type: Signal generatorMaterial: ABSWeight: Approx. 58g/2ozVoltage: 0-10VFeatures: Coarse and fine tuning dual mode, and the number of turns can be set separately; The minimum adjustment number of the knob is 0.01mA, and the last number is plus or minus 1; After calibration, the actual error is 0.01mA, with high accuracy linear output; 4 digit high brightness digital tube, with clear display; Digital encoder knob, durable, not affected by the environmentProtection: Output with short circuit protection, power supply with reverse connection protection
