The calibration procedure is similar to the section 5.1. But, the difference between them is
that the ET-7X00/PET-7X00 doesn’t directly support type code - 0E ~ 19 for AI calibration,
so you need to change the channel 0 as range - 00 ~ 02 to complete the work (refer to
section 5.1 step 3).
Step 1 Warm up the module for latest 30 minutes.
Step 2 Set the type code to the type you wish to calibrate.
Step 3 Enable calibration.
Step 4 Apply the zero calibration voltage to channel 0.
Step 5 Send the zero calibration command.
Step 6 Apply the span calibration voltage to channel 0.
Step 7 Send the span calibration command.
Step 8 Disable calibration.
For example
If you want to calibrate type 0E, you need to set the channel 0 as range - 01.
