Are you saying you have a signal conditioner that produces a 4-20 mA signal? The LJTick-CurrentShunt is the easiest way to handle 4-20. See the following:
I'm using a Labjack T7 Pro. I'm trying to experiment with a Model MEGGIT 41A19 accelerometers (two) to sense vibration. Since the accelerometer's output is in mV, . What would be the best way to wire each of these accelerometers ? How can I configure Labjack to display the output signal? How can I perform a calibration on the output signal?
Since you are trying to look at waveforms from a dynamic signal, LJStreamM is a likely choice to get started.
For calibration, you generally need a couple known points of acceleration where you note the voltage, and then you can come up with a scaling equation you use in software. 0g is a very common known acceleration, and using gravity to provide 1g is another common known acceleration.

exact , thanks a lot
Hello Labjack Support Team
I'm using a Labjack T7 Pro. I'm trying to experiment with a Model MEGGIT 41A19 accelerometers (two) to sense vibration. Since the accelerometer's output is in mV, . What would be the best way to wire each of these accelerometers ? How can I configure Labjack to display the output signal? How can I perform a calibration on the output signal?
Any help with this would be greatly appreciated.
Thanks,
I see that your accelerometer is an IEPE type. Do you have the special current source power supply these require?

Do you have any particular software plans?

ok thank you very much
i must buy a conditioner
Hello ,
i have choose this contioner : https://buy.endevco.com/amfile/file/download/file_id/1852/product_id/1781/
i need something to plug it on the T7 pro ?
thanks
That should work. The output appears to be on a BNC connector, so you just need to split that into a couple wires to connect to AINx and GND:

Thank you very much , a last question : do you have a official distributor in France ?
Yes, you can find them here:
