10. Set-point entry
Setting ranges Control ranges
Temperature
0.0 °C / 32 °F up to 110 ºC / 230 °F
10 °C / 18 °F above ambient temperature up to
110 ºC / 230 °F
Pressure 0 mbar up to 1100 mbar 0 mbar up to 1100 mbar
After starting the drying procedure, the heater is activated only when the pressure reaches or
falls below the required pressure threshold of 100 mbar.
Solvents and resulting vapors can ignite at excessive drying temperatures.
DANGER
Fire and explosion hazard when exceeding the auto-ignition temperature of the sol-
vent due to excess drying temperature.
Serious injury or death from burns and / or explosion pressure.
Make sure that only solvents with an auto-ignition temperature that is higher than
200 °C / 392 °F may be entered into the chamber. Check the auto-ignition temperature
with the safety specifications of the solvent. In the case of solvent mixtures, use the
auto-ignition temperature of the material with the lowest auto-ignition temperature.
In Fixed value operating mode, you can enter a temperature set-point, a pressure set-point, and the switch-
ing-state of special controller functions.
All settings made in Fixed value operating mode remain valid until the next manual change. They are saved
also when turning off the chamber or in case of toggling to Program Mode.
The values entered in Fixed value mode become valid again after the end of a program and
will then be targeted and equilibrated.
When operating without a vacuum by setting “Pressure control off” (chap. 11.5), the pressure
tolerance range function is automatically deactivated.
