reading 4 - 20mA pressure loop with 6211 usb

[johnnybond]

Hi,

I am using a usb 6211 multifunction DAQ and trying to continuously read 4 - 20mA signals from a Pressure Transmitter.

My problem is that I do not get a steady signal out.

The signal jumps about and wildly varies almost looking like it reads out of phase but i thought that the 4 - 20mA signal would be constant?

Does anyone have any ideas?

Cheers

Johnny
