4. Set the channels to be calibrated.
5. Click Next.
The Low Reference Voltage Signals wizard appears to show which
channels will be calibrated for a low reference and the range of the
calibration. It also shows what reference signal is expected at the input.
TIP
You can select whether to calibrate channels in groups all
at once or each channel at a time. The example above
shows channels 0,1 being calibrated at the same time for
instructional purposes.
We recommend you calibrate all channels on your module
each time you calibrate. This will help you maintain
consistent calibration readings and improve module
accuracy.
