The functions are available using the soft keys and are
described in sections 4.4 to 4.8.
4.3.1 Main screen temperature values
Two temperatures are displayed (A and B versions):
READ temperature: This is the temperature measured by the
internal reference sensor.
SET temperature: This is the target temperature for the well. SET
temperature displays the last value entered. If no value has been
entered previously, "Not Activated" is displayed.
Additional temperatures displayed (B versions only):
SENSOR temperature: This is the temperature measured by the
sensor being measured.
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 READ temperature.
4.3.2 Stability of temperature values
The stability of the READ, 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.
"Time to stable": Indicates that the temperature changes are within
the specified stability criteria (see chapter 8.0) and states a time (in
minutes) when the stable situation can be achieved.
"": Indicates that the “stable” situation is achieved.
SENSOR temperature cannot indicate "" unless the
READ or the TRUE temperature is stable.
If External reference (TRUE) is selected, the stability
criteria will refer to this. As default the criteria are as
follows:
