4-20mA Transducer Read each ok - scan three get same reading

[MattRIT]

I have three 4-20mA pressure transducers connected to SCXI-1100 thru a SCXI-1303. Installed 249ohm NI resistors in 1100 to measure current. In MAX or reading each transducer by itself I get good data. When I try to scan all three, I get the same reading for all three. Does this sound like the interchannel delay is too short or could I have jumpered the 1100 wrong??

If MAX is reading the corrrect values it is unlikely that you have a hardware setup problem. MAX is designed to allow you to perform diagnostics and verify hardware performance independant of any other software program (LabVIEW, LabWindows...). Since you are able to read the correct value for a single channel scan and unable for a multiple channel scan, I suspect you may be using an incorrect format(syntax) for the multiple channel call. Also, is it possible you are viewing the output array in transposed form? If you could let me know the syntax of your channel call, I will try to provide more help.

Thank you...I now have all three transducers reading correctly.
