It is not recommended that calibration be performed until
the process is fully understood.
1.8.2. The calibration procedure for ET-7017 and ET-7017-10:
1. Warm up the module for at least 30 minutes.
2. Set the type code to the type you want to calibrate.
3. Enable calibration.
4. Apply the zero calibration voltage/current to channel 0.
5. Enable the zero calibration register.
6. Apply the span calibration voltage/current to channels 0.
7. Enable the span calibration register.
8. Disable calibration.
