FP-AI-110 out of range error

[GNR]

Hello, I'm new to FieldPoint. I have a problem with FP-AI-110. The voltage I want to measure is 8 volts. I have set the range from -10.4V to 10.4V in MAX explorer for channel configuration. The voltage is verified with DMM and it's about 8 volts. The problem is that sometimes I can get correct reading but sometimes I get the error code 33487 which means out of range. What could be the reason for this? Thanks very much.

In your program, are you reading just one channel or multiple channels? If reading multiple channels and some are not connected to anything, their inputs will 'float' and may go out of range.
