The numerical format
All temperature values will be shown in a unit numerical format. If the mode
‘DEFAULT’ is selected each bit corresponds to 0.1°C. The possible numerical range
refers to the standardized temperature range of the used sensors. The following table
will explain the numerical format on a preset PT100. In the third column the numerical
format for PT1000 (750-461/000-003) is explained.
