The modules are calibrated during manufacture and should not need to be
calibrated again to operate properly; however, a maintenance schedule to
check accuracy every six to twelve months is recommended.
If the accuracy is not within specified tolerance at 25 C, recalibrate the
module. You must calibrate the module with the CPU in program mode, not
in RUN mode.
Calibrate the module with or without a Euro-extender card (Euroboard)
using the procedures outlined in the following sections.
