(c) Settable temperature range and default value vary according to the RTD type to
be used and measurement range.
Values are set in units of 0.1 .
(d) When time average or count average is specified, process alarm processing is
executed for each preset time or count.
When other temperature conversion system (sampling processing, moving
average or primary delay filter) is specified, process alarm processing is executed
at every sampling period.
(e) When disconnection state is detected, the measured temperature value is
replaced with the setting in the Conversion setting for disconnection detection
(Un\G164 and Un\G165), such as "Down scale". As a result, a warning may occur.
