7.3.3.2. Stabilisation of internal temperature

Picture 75.

Analyser settings – Stabilisation of internal temperature

The analyser is capable to stabilise its internal temperature by cooling the temper-

ature down using the fan. This way the electronic components are protected against over-

heating. In section “

Stabilisation of internal temperature”

, one can set:

•

Enable the temperature stabilisation.

•

Set the target temperature that the analyser would try to adjust to. The default Tar -

get temperature is 28°C

•

Set the Regulation hysteresis.

The fan starts when the T

INT

(temperature inside of the analyser) exceeds the value = Tar-

get tempe Regulation hysteresis.

The fan is stopped when the T

INT

drops below the Target temperature.
