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.
