Executing AutoDest mode
Automatic distillation requires the use of an AutoDest sensor. The AutoDest sensor is
connected to the VacuBox (see Chapter 5.3 "Connecting AutoDest sensor to vapor
temperature sensor (optional accessory)", page 39) and measures the inlet and outlet
temperature of the coolant and the vapor temperature at the cooling condenser. From
those three readings, the system calculates the parameter settings required for opti-
mum distillation. During automatic distillation, the temperatures of the heating bath,
coolant and vapor are constantly measured and the specified setting for the pressure
adjusted accordingly.
CAUTION
Risk of personal injury and property damage from unexpected equip-
ment behavior
u
Always carefully check the pre-programmed settings before every distillation
process.
