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: 110V/ 115
V/ 230V, ±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 QIAamplifier 96 checks several functions and components:
Test
Function
Cooler
Incubates the sample block to 4°C and checks if the temperature in the block is reached and
can be held for a longer time
Thermal tracking
Checks the synchronism of the control circuits and if they work together in a coordinated way
Heating and cooling
rate
Checks if the specified average heating and cooling rate is reached
Refrigeration
Checks if the heat sink and the fans are working properly together
Gradient
Checks if the sample block reaches the set gradient temperatures
Heated lid
Tests if the heated lid reaches the set temperature and can hold it for a longer time
Regulation
Tests if the sample block is controlled properly
The QIAamplifier 96 software will automatically recommend at regular intervals to carry out an
extended self-test. Although it is not absolutely necessary to perform the test, we highly recommend
to follow the prompt and to let the device check itself.
Before starting the extended self-test, insert a microplate or, if applicable, two strips or a row of
tubes in the first and last row of the sample block (see Figure 60). It is very important to load the
sample block as described with plasticware because during the extended self-test the operation of
the heated lid is tested and this test can only be carried out with a correctly loaded sample block.
The position of the plasticware in the block is also very important to ensure optimal contact pressure
and uniform horizontal alignment of the heated lid.
