Analog readings on PCI7332 motion card

[tompeelle]

I am using three analog inputs with a single axis open loop strpper. channel1,3,4

Channels 1 & 3 work fine, but channel 4 doesn't. First of all it seems too drag the input from 3volts to .8voltd I have an Analog Device

5B Islation amp connecting signal to channel 4.  When you increase the signal the reading of the read goes from 317 to 850.

the channel is configured for 0-5 volts. what am I doing wrong.

What happens if you connect the signal that is currently attached to channel 4 to another channel (1 or 3)? Do you see the problem now with the other channel? In this case you should check your signal and the signal conditioning.
If you can't reproduce the problem with the same signal and another channel you should contact your local National Instruments branch as the board probably needs to be repaired.
