A. The SG-003A signal generator is mainly used for debugging of industrial field PLC, process instrumentation, electric valve and so on. It has a friendly operation interface which is easy to use. The SG-003A signal generator is small and light, has a long standby time and high precision, and is easy to carry when going out to work. Adjustable button backlight and a high-definition TFT color LCD screen make it more convenient for users to operate during the day and at night. B. In addition to the conventional signal input and output functions, voltage and current have an automatic output function. It can operate in three modes: single rise, single drop. It also has input to output conversion, voltage conversion to active current mode, passive mode and current conversion to voltage mode. C. The output has a custom function, and the upper and lower output limits can be set arbitrarily. For voltage input and current input, the rate is 10 frames. The PWM output can set frequency and duty respectively. D. Real-time observation of changes in voltage and current is possible. It is powered by a lithium battery with a Type - c interface (5V). The capacity of the lithium battery is 3000mHA, providing super long working hours. E. The high-definition TFT color LCD screen makes the reading more eye - catching. The resolution is 240*320, and it has low power consumption. The maximum power consumption is 0.32W. F. Parameters: 1.
