DASYLab & Personal DAQ 3000 Series Help

[Leson]

Hi, I'm running a PersonalDaq 3000 Series in conjunction with DASYLab.

The issue I'm dealing with is I'm getting unstable readings.

The inputs to the board are from thermocouples (type J), and pressure transducers (single-ended and 0-5v output range).

Since the thermocouples have to be read using the differential setting, I configured it so all inputs are differential. (The board forces all outputs to be single ended or differential, no combo)

The outputs, seem to work sometimes, but then suddenly they destabilize, outputting strange values.

Is the issue possibly caused by the single ended pressure transducers and the fact that they aren't differential in nature?

Note, another reason I'm using the differential setting is cause of the noisy environment that its supposed to function in.

Please advise.

Niether DASYLab or Personal DAQ 3000 are supported here. I would suggest going to the mcc site for help.

DASYLab can be supported here as well,

The pressure transducers should have the - input jumpered to the AGND this would help for those.  Also make sure that the themocouples, if mounted in a metal enviroment are also properly grounded.

Grounding is our worse enemy
