1.8. Calibration

It is not recommended that calibration be performed until
the process is fully understood.

1.8.1. The calibration procedure for ET-7015:

For the ET-7015, each channel should be calibrated separately and only the channel being
calibrated should be enabled during calibration.
1. Warm up the module for at least 30 minutes.
2. Enable the channel you want to calibrate and disable other channels.
3. Set the type code to the type you wish to calibrate.
4. Enable calibration
5. Connect the zero calibration resistor to the enabled channel.
6. Send zero calibration command.
7. Connect the span calibration resistor to the enabled channel
8. Send the span calibration command.
9. Disable calibration
