Custom Measurement Scales

sidesh0w@my-deja.com — Sun, 29 Oct 2000 15:13:16 GMT

Hello All,

I am fairly new to LabVIEW and I have a question. I need to take 3
measurement points from an LVDT that are at a known measurement
(ie. .050 , .065 , and .080 inch) and take the voltages at those three
points and rewrite a scale that was created in Measurement and
Automation Explorer. These need to be done as a first step when
running the VI.

Any ideas?

Thanks for your help in advance,
Chris

Hello Chris,

The link that WildEnte provided is a great example of how to change a scale created in Measurement and Automation Explorer using LabVIEW. This knowledgebase provides some information on how the property nodes in this example were created.

An important thing to note is that a DAQmx scale that is assigned to a task can be changed while the task is running, but any changes made to the scale will not be shown. To have the changes to a scale show for a task, the task must be stopped and cleared from the DAQ device. Once the task is reconfigured and started with the new scale settings, the changes to the scale will take effect.

Please post back if you have additional questions regarding this issue and I will be happy to help you out further.
