switched off; for class 3.2, the cooling. As soon as the actual tem-
peratur
e is back within the limits, the incubator will continue to regu-
late. The temperature guards serve as device protection and sample
protection. The temperature limits can limit the standard temperature
range.
In the "Temperature guard" settings, temperatures for classes 3.1
and 3.2 can be input.
For 3.1, up to +70 °C
For 3.2, from -10 °C up to +70 °C
If classes 3.1 and 3.2 are set, they must lie at least 4°C / 8°F apart.
It is only sensible to use a temperature guard of class
3.1 in heating mode with monitoring temperatures
which lie above room temperature.
The temperature specication value can be changed by tapping it.
The setting ex works is +70 °C. This temperature lies outside of the
temperature range of the incubator. Class 3.1 here acts like device
protection, but is not indicated as being active on the main screen. If
the setting is changed, the class 3.1 is indicated as being active on
the main screen.
■ Target temperature +37 °C, class 3.1 at +40 °C
