I.    Description:
This example demonstrates how to acquire resistance data using software timing.

II.   Instructions for Running:
1. Select the Physical Channel(s) to correspond to where your signal is input.
2.  Enter the minimum and maximum Resistance Ranges.
Note:  For better accuracy try to match the Input Ranges to the expected resistance level of the measured signal.
4.  Enter the Resistance Configuration, the current excitation source, and the excitation value in Amps.
Note: Certain devices have specific settings that can be used for Resistance Configuration, Current Excitation, and Excitation Value.  If these devices are used, then the inputs given on the front panel must match one of the valid configurations for the device.  For example, you must input one of the supported values for Excitation Value for that specific device.

III.  Block Diagram Steps:
1.  Create an Analog Input Resistance Channel.
2.  Read the data.
3.  Call the Clear Task VI to clear the Task
4.  Use the popup dialog box to display an error if any.

IV.  I/O Connections Overview:
Make sure your signal input terminal matches the Physical Channel I/O Control.
For further connection information, refer to the hardware reference manual for your device

使用NI的卡建立采集，其中须设定DAQmx timing
其它一些设置都是DAQ采集中所须要，

设定DAQmx timing有什么用,而电流激励产生是怎么回事
