Are the AI channels calibrated?

When reading the LSBWeight and Offset properties for the ConnectorA/AI0 channel,  I get:

LSBWeigh = 1220703  (I assume this is nV/LSB)

Offset        =  0           

This looks awfully good to be true (i.e., these are the ideal values if you have 5V/4096 LSBs)

When I short the input to ground, I read 4.88mV, which is about 4LSB, which means there is some offset error.

In cRIO analog modules, the LSBWeight and Offset properties contain calibration information (measured in manufacturing) which you can use to correct for gain and offset in each channel. Is this not the case with MyRIO AI and AO channels?

Thanks!

No, the myRIO analog channels are not calibrated.
