Vhat dee heck am I doing wrong here?
I am using an SCXI-1120 amplifier and an SCXI 1320 terminal block.
I want to put a voltage input onto ai4, so I follow the instructions and connect the V+ lead to J6+ and V- lead to J6-.
Now, I start to monitor voltage readout using MAX.
When I short the leads together, the voltage shows 0.
When I put a 1.5VDC battery in series with the leads, the voltage shows 5.28VDC, which I assume is the maximum value it can show.
All the other channels work fine.
Am I missing something? Or is this channel fried?
Solved! Go to Solution.
Looks likely that it is a fried channel. I checkde ai3, and it is working fine.
Any troubleshooting advice?
Do you have other 1320 modules and 1120 terminal blocks you can try in different combinations? Is it just this module, on this channel?
There are also jumpers inside the module that you can configure the gain and filter settings. I would inspect specifically the jumpers relating to that channel. There are also some differences in the 1120 and the 1120D, besure to note which module you have and the changes in the user manual.

A colleague of mine showed me those very jumpers this morning.
