A/D channel Manual-Calibration
Step 1: Click the Manual A/D Calibration tab to show the A/D
channel manual calibration panel. Before calibrating, acquire
the reference voltage from a precision standard voltage
reference. Go to the Range form, select a channel and the
target voltage range according to the input voltage value
from a precision standard voltage reference(Fig. 5-15).
Note:
✎ The input voltage value you selected from a precision standard
voltage reference needs to correspond with the one that the PCI-1716/
1716L can read.
✎ The input voltage will be analog code so the computer will convert the
voltage data into digitial code; therefore, the input voltage value you
selected from a precision standard voltage reference needs to
correspond with the one that the PCI-1716/1716L can read. For
example, if the input range is 0 ~ 5V, then input voltage should be
2.9992V not 3V.
