Input range selection on E-series boards in differential mode

I'm using the Hardware Configuration VI to set up a PCI-6071E
card for *differential* input mode and passing it an array of channels:

38,2,39,3,38,4,39,6,38,7,39
(note that I'm sampling channels 38 and 39 three times as fast as
channels 2,3,4,6,7. Using 38 & 39 in the list addresses the 23rd and
24th channels on the card in differential mode)


I'm passing the Hardware Configuration VI a corresponding array of input
ranges:

+-5,+10,+-5,+10,+-5,+10,+-5,+10,+-5,+10,+-5
(these should correspond with the channel list above, so channels 38 &
39 are in bipolar +-5V, and the other channels are set to +10V unipolar)

However, all the channels go into +-5V mode. If I change the input
range
for the first channel in the list to +10V then all channels go to +10V.
The card is supposed to be able to do separate ranges for each channel
(but maybe it can't in differential mode?)

What's going wrong?

(I'm using Labview 5.1 and Windows 98)

You might consider re-posting this question in the "multifunction IO" category of the "Measurement Devices" section. This newsgroup discusses LabVIEW Datalogging and Supervisory Control, which is an add-on package for LabVIEW that expands SCADA capabilities under LabVIEW.

I want used to pci-6024E to take 0.5mV ~ 50mV prcision
0.01mV, Is it can do it?
thanks
