Measure Voltage

[madanchi]

Hi, I am new to LabView and I need to make a program that will automatically display measures of voltage shown on a Agilent 34401A onto a graph. These measures must be recorded into a text file. I looked through an example but I did not understand how most of it works. Can anyone explain to me the example and/or possible ways to make my program? The example is attached. Thanks

No need to attach a VI that is included with every version of LabVIEW.

What exactly is confusing. If you have context help turned on, you can see an explanation of every function. If you have studied the instrument and the manual, you should have a basic understanding of what is going on and why. Did you run the most basic example - Agilent 34401 Read Single Measurement?

HI,

Per the description  "This example shows how to configure a software triggered measurement using the low-level Data VIs to retrieve data from the DMM."

Generally speaking the drivers are used to initialize the instrument (1st VI) , then configure the measurement (2 -5th VI) , then start a trigger, measure data, and then close the instrument.  From the measurement Driver you can take the data and save to a file.

In this example the 6th VI starts the 'task', but since this task is set for a trigger the 8th VI is used in a loop to send triggers.   The 9th VI gets the measurements.

Do you need software triggered measurements?

try to attached vi. I have never worked with agilent 34401 but this vi could work. I worked with 34901 and it is really took me too time to configure it. first be sure that your port configuration is suitable for the device. the attached vi is too primitive. you should attach them some configuration. I really do not know whether it works or not I attached it to give you an idea on it.
