Operation and Control
5.10.7 Settings example programme mode
On Monday at 8.00, the cooled incubator should heat up to 37 °C as quickly as possible with
a fan speed of 30 %, and reach a relative humidity of 70 % rh. For models with CO
2
supply,
the CO
2
content should be set to 5 % and for models with interior lighting, daylight should be
simulated.
Once the temperature and humidity have been reached, the cooled incubator should retain
the setpoint values at a fan speed of 50 % for 45 minutes. For models with lighting, the test
samples should be subject to UV light and daylight during that time.
Afterwards, the appliance should cool down to 20 °C and reach 50 % rh humidity within 1
hour at 30 % fan speed. For models with CO
2
supply, the CO
2
content should be adapted to
the natural content of the ambient air and for models with interior lighting, daylight should
be simulated. The overtemperature protection should trigger at 38.5 °C.
