Subject: [foxboro] My RTDs don't go below zero

We have found that our RTDs don't read below zero.  Is there some I/A or =
instrument related issue that can explain this?

Our RTDs are directly wired to an FBM03.  The AIN block has an SCI of =
42.  It has a scale configured to show -10 deg C to 150 deg C.  We are =
using 6.1.1 software.

When the measured temperature is below 0 deg C, the block shows I/O bad.

Thank you for your help.
