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:

n 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.

n The input voltage will be analog code so the computer will convert the

voltage data into digital 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.
