(SEN0464)Gravity: Analog Industrial ORP Sensor Meter Pro for Arduino

I am currently attempting to integrate the Gravity: Analog Industrial ORP Sensor Meter Pro with an Arduino board. However, I have not been able to locate a user manual providing instructions on how to use the sensor, including details on calibration, immersion in water, and other relevant procedures. Could you please provide guidance on how to calibrate the sensor and demonstrate the proper method for immersing it in water, possibly with a video tutorial? Additionally, I would appreciate clarification on whether the sensor cap should be removed and how to ensure that the liquid remains inside the cap. Lastly, I would like to know the recommended procedure for standardizing the sensor using chemical solutions. Should the sensor be dipped with or without the cap for these processes? Any assistance in improving my project would be greatly appreciated.
