3. Insert the pin at 5V
4. Analog Voltage Output: The following is the output voltage of 0-10V to illustrate
After power-on, when there is no input signal, the output is 0V
For the first power-up, a calibration can be done: Input a signal with 50% duty cycle and 3.3V amplitude to DIN- and DIN . The frequency is 1-3KHZ. Use a multimeter to measure two ports of AO and GND. Adjust the potentiometer on the board to make the multimeter display 5.40V. This calibrate the corresponding relation between pulse signal and this module. The resolution of this module is 0.1V. The output current capability is 10MA.
