Measures
1. Check the setting of the temperature limit (parameter “Al.5”) (Table 3 on page 30 or Table 4 on page
31).
The value of parameter “Al.5” should be at least by 5 °C above the value of parameter “SP”.
If necessary, change this parameter.
2. Check whether samples were inserted into the chamber that produces heat under the climate
conditions in the device.
3. Check the ambient temperature.
The ambient temperature must be below 32°C.
The unit must be protected against direct sunlight.
The installation location must be sufficiently ventilated to prevent any build-up of heat in the device.
4. If you can exclude points 1. to 3. as the source of the fault, the device might be faulty. Please
contact your local Datacolor service representative.

Measures
1. Check the ambient temperature. The ambient temperature must lie between 18 and 32°C.
2. Regarding to the displayed actual temperature, check if the set-point temperature (parameter “SP”)
has been exceeded or fallen below.
3. Check if a prolonged door opening has caused the temperature deviation. In this case, no further
actions are required. If appropriate, mute the buzzer.
