Description : FNIRSI SG-003A signal generator is mainly used for debugging of industrial field PLC, process instrumentation, electric valve and so forth. Friendly operation interface is easy to use. The FNIRSI SG-003A signal generator is small and light but has a long standby time and high precision.Easy to carry when you go out to work. Adjustable button backlight and high-definition TFT color LCD screen make it more convenient for users to operate at night and during the day Features : 1. Expect with the conventional signal input and output functions 2. Voltage and current have automatic output function,it can choose a single rise,three modes of single drop and cycle. 3. With input to output conversion,voltage conversion active current mode,passive mode and current conversion voltage mode. 4. The output has a custom function,the upper and lower output limits can be set arbitrarily. 6. Voltage input diagram,current input diagram,the frame rate is 10 frames. 7. PWM output can set frequency and duty cycle respectively. 8. Real-time curve:Real-time observation of changes in voltage and current 9. It is powered by a large-capacity lithium battery and is charged with a Type-c interface (5V).The capacity of the lithium battery is 3000mHA,Super long working hours 10. The high-definition TFT color LCD screen makes the reading more eye-catching.The resolution is 240*320.Low power consumption,Maximum power consumption: 0.32W Technical Parameters: 1.
