Features: brand new and high quality 1 Small jitter: 0.1mV jitter change, suitable for controlling the occasions with high ripple requirements, at the output and someCapacitors may work better ( pay attention to capacitor polarity); Can be set to a variety of outputs: dual output ± 10.00V / ± 5.00V single output 0-10.00V / 2-10.00V...0-1.00V and so on.When single output is 0V can really reach 0, it is suitable for this output occasion of small signal such as 0-1.00V. Digital Encoder Knob, how much is output when it is rotated Knob rotates the coarse and fine adjustment dual mode, the number of turns can be set to 1-100 circles; 4-digit digital tube, 0.01 change, setting and adjustment value power-down storage; Specifications: Power Supply Voltage: DC8-28V Power 1W Maximum Output Voltage Range: ±10V Maximum Load Current: 20mA Accuracy: 0.01V Encoder Knob One Pulse Number: 20 4-Digit 0.4 inch Digital Tube Package Includes: 1 x Voltage Source Signal Generator note: Due to the problems of lighting effects and shooting angles, there will be certain tolerances in the product, please understand. Please allow 0-1cm error due to the manual measurment.
