Extended Self-Test
NOTICE
The Extended Self-Test must be performed under the following conditions to achieve
reproducible 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
C
OOLER
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.
T
HERMAL TRACKING
Checks the synchronism of the control circuits and if they work coordi-
nated together.
H
EATING AND
COOLING RATE
Checks, if the specified average heating and cooling rate is reached.
R
EFRIGERATION
The cooling sink and fans are checked to work properly together.
