FP-AI-111 channel drifts by 2-3mA and is slow to respond; Can NI repair it?

[Loren]

I am using an FP-AI-111 module. I think I accidentally applied a short to the input (extream overcurrent). The module channel receives a signal but it is slow to respond and it drifts up and down by 2-3ma. The problem also follows the module when I move it to another Terminal Block position.
Are these the common symptoms of a blown channel? Can it be repaired?

Loren,

You can get the module repaired. All you need to do is call National Instrument's technical support to start the return process.

To test if you damaged the channel, you can measure the resistance between any input channel of the FP-AI-111 and common. If it does not read 100 Ohms (within the accuracy of the DMM), you damaged the channel.

Also, the FP-AI-111 has a variable update rate depending upon the input filters. If all
16 channels are set to 500 Hz, the update rate (for all channels) is 290 ms. If all 16
channels are set to 50 Hz, the update rate (for all channels) is 1230 ms. For details on calculating the update rate, please see the FP-AI-111 Operating Instructions.

For module repair, can NI Tech Support for an RMA number.
