11.4 Extended Self-Test
NOTICE
The Extended Self
-
Test must be performed under the following conditions to achieve re-
producible and meaningful results:

Ambient temperature in the range 20 °C to 25 °C

Mains voltage depending on the voltage type of the device: 100 V/115 V/230,
±10 % each

The device must be cooled to the ambient temperature of 20 °C to 25
°C after the last
application.
During the Extended Self-Test the Biometra TRIO Thermal Cycler checks several func-
tions and components:
Test Function
Cooler Incubates the sample block to 4°C and checks, if the sample block reaches
4°C and if the low temperature is hold for a longer time.
Thermal track-
ing
Checks the synchronism of the control circuits and if they work coordi-
nated together.
