Using the Autoranging Voltmeter

Open a new VI in LabVIEW. Then Right Click on the Diagram, and go through Functions>>Select A VI.... and locate ProjectA.llb.
Click on Voltmeter.vi and Click OK. Place the icon on the Diagram. Double Click on the icon to get the Front Panel.
Now place AO Update Channel.vi in the Diagram of your new VI. This is in Functions>>Data Acquisition>>Analog Output.
Double Click on the icon to open the VI. Set the device numbers to match that of your DAQ. Verify that output channel 0 (Chan0_out) is connected directly to input channel 0 (Chan0_in) on the connector block or circuit board. Now run AO Update Channel.vi repeatedly to send out a series of voltages, such as 0.09 V, 0.9 V and 9 V and for each, run Voltmeter.vi. Observe the automatic changing of the limits setting for the various voltages sent out. Note that the voltage is always measured with good precision. Try a negative voltage out.
