NOTICE
When the temperature control is
active, the menu is locked, while
all the selection buttons on the
main screen are active.
•
Press the “Menu” key (C).
•
Select the menu by turning the rotary/push knob (E) clockwise
or anticlockwise to select the desired menu or sub-menu, which
can then be selected by pressing the rotary/push knob (E).
•
Push or turn the rotary/push knob (E) again to select the de-
sired menu option and edit the values or settings, or activate/
deactivate a function.
•
Turn the rotary/push knob (E) on “OK” or press the “Back”
key (D) to end the procedure and return to previous menu or
working screen.
Internal / external temperature sensor
The temperature is regulated according to the internal/external
temperature sensor.
Temperature monitoring
You can monitor the temperature behaviour. If the temperature
behaviour exceeds the defined hysteresis value, the
symbol ap-
pears at the actual temperature.
Hysteresis
This enables the temperature control function of the device to
switch off when the actual temperature exceeds the specified hys-
teresis value. It also defines the permitted tolerance of temperature
variation.
Calibration and adjustment
This makes it possible to adapt the temperature display, to get
more precise temperature regulation.
•
Internal temperature sensor / external temperature sensor:
The external/internal temperature sensor is adapted here us-
ing the 3-point calibration.
Actual temperature note
Gives a notification when the actual temperature is in the range
of ± 1.0 K of the target temperature and the
symbol is shown
next to the target temperature.
Timer (Zeitschaltuhr)
Counter (service hour counter)
The counter function counts as soon as the heating function is
active. The maximum value is 9:23:59 (Days: Hours: Minutes).
Timer (adjustable operating duration)
The timer function starts as soon as the temperature control func-
tion is active. The remaining time is shown on the display. When
the specified time has elapsed the heating function is switched
off. The maximum value is 9:23:59 (Days: Hours: Minutes).
Control
Counter and timer setting options:
•
Time
: The counter and timer are controlled depending on
the time. The counter and timer start running immediately,
whether the target temperature has been reached or not.
•
Temperature
: The counter and timer work according to tem-
perature. They only start running when the target tempera-
ture has been reached.
Menüdetails
Temperature control
Control mode
The option of changing between two PID modes, and the tem-
perature reference sensor.
Exact PID control
For use with temperature-
sensitive materials that must
be handled with care.
Advantages:
•
Precise temperature control
•
Minimum deviation above/below the target temperature
Disadvantage:
•
Longer heating up time
Fast PID control
For use when a fast heating
up time is needed and there
should then be precise tem-
perature control.
Advantage:
•
Short heating up time
Disadvantage:
•
There will be a certain level of deviation above and below the
target temperature.
