Greetings everyone.
I am performing a tensile test on an electrical wire. The problem is that the copper inside breaks before the rubber protection outside, and what really matters to me is the Tensile Strength of the copper inside. One way to find out is by using a multimeter to test continuity by testing the current passing through. When the copper breaks, the current will be zero.
What I actually need is to record the current values from the multimeter alongside their corresponding Tensile Strength simultaneously in an Excell sheet. The bigger problem now is that the BlueHill (Interface used by Instron) does not have this feature. Therefore, I need a way to interface LabVIEW with INSTRON, or any way to record the current simultaneously with the Tensile Strength.
Sorry for the lengthiness and thank you in advance!

This should be fairly straight forward once we (you) know how to talk to the Tensile Strength transducer and you have a multimeter that you can communicate to.
What type of multimeter are you using? You cannot use a standard handheld multimeter, you need one with an output (serial, ethernet, etc). Most multimeters will probably have a driver already on the LabVIEW website, just search for a model number.
How does Bluehill get the data from the transducer (serial port? what is the protocol)? Do you have a manual with SCPI or any other commands?

Then I recommend that you contact Instron to see if they have a programmers manual, which would tell you how to get the data out directly from the transducer.
But this means that you will not get a report out of Bluehill software, if that matters.

Hi, did you find a way to sync Intron data with other signals in Labview? I have a very similar question with syncing Instron compressive data with encoders. Thanks much!!!
