6–2 Calibrating Your Module
    
If a calibration check of your module becomes necessary:
1. Verify that the module is in voltage mode. In single-ended mode,
apply voltages to channels 1 through 16.
2. Send a configuration block transfer write to the module that
replicates the specific application. (This forces the module to do
an internal calibration.)
3. Apply –10V, –5V, –2.5V 0V, 1V, 2.5V, 5V, and 10V to the
module. In differential, apply voltages to channels 1 through 8
Verify that the values returned are within 0.1% of bipolar full
scale. .
