5.12 _9114_AD_Set_Range
@ Description
This function is used to set the A/D range by means of writing data to the
AD range control register. The initial value of gain is '1' which is the
default setting by PCI-9114 hardware. The following tables specify the
relationship between gain and input voltage ranges:
For PCI9114HG:
Input Range (V) Gain Gain Code
±
10 V X 1 AD_B_10_V
± 1 V X 10 AD_B_1_V
± 100m V X 100 AD_B_0_1_V
± 10m V X 1000 AD_B_0_01_V
For PCI9114DG:
Input Range (V) Gain Gain Code
± 10 V X 1 AD_B_10_V
±
5 V X 2 AD_B_5_V
± 2.5 V X 4 AD_B_2_5_V
± 1.25 V X 8 AD_B_1_25_V
@ Syntax
C/C++ (DOS)

C/C++ (Windows 95)
U16 W_9114_AD_Set_Range (U16 cardNo, U16 ADRange)
Visual Basic (Windows 95)
W_9114_AD_Set_Range (ByVal cardNo As Integer, ByVal
ADRange As Integer) As Integer
@ Argument
cardNo: The card number of PCI-9114 card initialized
ADRange: The programmable gain of A/D conversion, the
possible values are: AD_B_10_V, AD_B_1_V,
AD_B_0_1_V, AD_B_0_01_V, AD_B_5_V, AD_B_2_5_V,
AD_B_1_25_V,
