Calibration Using Communications
The calibration process proceeds as follows:
1. Enter Calibration mode
2. Perform calibration
3. Store the calibrated values
4. Return to operation mode
The commands necessary for calibration are listed below.
For the input connection method, see "Input Range Calibration" on page 3-2.
DSp1 Switch to setting mode
p1 0 Switch to operation mode
1 Switch to Set up mode
2 Switch to A/D calibration mode
