Operation and control
5.6.3 Basic operation
All operating functions are selected by turning the push-turn control to the
left or right ...
... ... and adjusted by turning it with the SET key held down.
5.6.4 Setting parameters
Normally, all setting actions on the operating panel described on the following pages are
made in the same way:
1. Select the desired parameter with the push-turn control (menu item, e.g.
temperature), then all other parameters go dark and the selected one flashes.
2. With the SET key held down, set the desired value (e.g. 58.0 °C) with the push-
turn control.
3. 3. Release the SET key, and the set value is saved. The display briefly shows
the set value, flashing. Then the current temperature is displayed and the test
chamber begins to heat up or cool down to the set temperature.
4. Settings for other parameters are made in the same way.
The control returns automatically to the main menu if the push-turn control or SET key is
not operated for approx. 30 seconds.
5.7 Operating modes
TTC temperature test chambers and CTC climatic test chambers can be operated in four differ-
ent modes:
► Normal mode: The test chamber runs in permanent operation at the temperature, humid-
ity and fan values set on the operating panel. Operation in this mode is described from
page 30 .
► Week time switch: The test chamber runs at the set values only at certain times. Operation
in this mode is described from page 33 .
► Programme mode: Time sequences of temperature, humidity (only with CTC 256) and fan
values are programmed (so-called ramps), which the test chamber automatically works
through one after another. Operation in this mode is described from page 35 .
► Interface mode with PC/laptop (optional, see page 43 ).
