Performing an extended self test
During the extended self test, the device checks the most important device functions and
components. The software will prompt you to carry out an extended self test at regular
intervals.
}
The following conditions must be met for the software to generate reproducible test
results:
– Mains voltage: 100 V; 115 V; 230 V ±10 %
– Ambient temperature: 20 to 25 °C
– The sample block must be cooled to ambient temperature.
}
Insert a microtiter plate or a series of individual sample tubes into the first and last
columns of the sample block to ensure optimum contact pressure on the heated lid
during the test.

During the following approximately 30 min the software will carry out the follow-
ing tests:
Test
Description
Cooler
Incubates the sample block to 4 °C and checks if the temperature
in the block is attained and can be held for a longer period of
time.
Thermal tracking
Checks the synchronicity of the control loops and whether they
interoperate in a coordinated way.
Heat.-/Cool rate
Checks whether the device attains the specified average heating
and cooling rate.
Refrigerati.
Checks whether the heat sink and the fans interoperate properly.
Gradient
Only for gradient-enabled models
Checks whether the sample block attains the predefined gradient
temperatures.
Lid
Tests whether the heated lid attains the predefined temperature
and can hold it for a longer period of time.
