4.3.2 Main screen temperature values
Two temperatures are always displayed:
TRUE temperature: This is the reference temperature of the
calibrator. In the A-version this is always the internal reference
sensor. In B- and C-versions the TRUE temperature can either be
the internal reference or the external reference.
SET temperature: This is the target temperature for the well. SET
temperature displays the last value entered. If no value has been
entered previously, "---,---" is displayed.
Additional temperatures displayed (B versions only):
SENSOR temperature: This is the temperature measured by the
sensor under test (SUT).
Additional temperatures displayed (B and C versions only):
Ext. TRUE temperature: This is the temperature measured by an
external reference sensor. This is only displayed when an external
reference sensor is used and replaces the internal reference.
4.3.3 Stability of temperature values
The stability of the TRUE and SENSOR temperatures are indicated by
the following messages:
"Not stable": Indicates that the measured temperature is not
yet within the specified stability criteria.
Indicates "Time to stable": The temperature changes are
within the specified stability criteria (see chapter 8.0) and
states a time (in minutes and seconds) when the stable
situation can be achieved.
: Indicates that the “stable” situation is achieved.
If External reference is selected as TRUE, the stability
criteria will refer to this.
