5.17_9111_AD_Set_Range

@ Description

This function is used to set the A/D range by means of writing data to the gain control register. The initial value of gain is '1' which is the default setting by the PCI-9111 hardware. The relationship between gain and input voltage ranges in the following table:

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
±0.625V	X 16	AD_B_0_625_V

@ Syntax

C/C++ (DOS)

U16 _9111_AD_Set_Range (U16 cardNo, U16 ADRange)

C/C++ (Windows 95)

U16 W_9111_AD_Set_Range (U16 cardNo, U16 ADRange)

Visual Basic (Windows 95)

W_9111_AD_Set_Range (ByVal cardNo As Integer, ByVal ADRange As Integer) As Integer

@ Argument
cardNo:	The card number of PCI-9111 card initialized

ADRange: The programmable gain of A/D conversion, the possible values are: AD_B_10_V, AD_B_5_V, AD_B_2_5_V, AD_B_1_25_V, AD_B_0_625_V.

@Return Code

ERR_NoError
