Safety instructions
WARNING
Risk of burns from chamber heating up unexpectedly
If too high a temperature has previously been set then burns could occur after
switching on the control unit.
After use reset the temperature at the control unit to room temperature.
Observe which set temperature appears on the display after switch-on and, if
necessary, set a lower value.
!
The Peltier element could be damaged if it is heated up without counter-
cooling.
Always switch the thermostat on before the control unit and set a suitable
temperature.
Make sure that the flow is not impeded by kinks in the tube.
11.8.2
The temperature controller
The required temperature is set by using the CONTROLLER element on the control
unit of the TC40.
Immediately after the mains switch is switched on, the control unit initializes itself
and is ready for use after about 3 seconds.
Temperature display
The top line indicates the current temperature of the heating elements.
The set temperature is shown in the lower line of the display.
The temperature measured by the external temperature sensor is not displayed.
To display this, please refer to the DSA software manual.
