14. Quality Control

Each institution must establish its own QC policy.
To check the performance of the device, we recommend measuring the temperature with a
thermocouple. The temperature accuracy can be checked with the NANOCOLOR
(REF 919921) or NANOCOLOR
temperature probes are suitable for checking the device in case of a deviation and for adjusting
the device.
Pressing in Settings
Press the key to open the test menu. In the test menu all programmed temperatures are

Pressing the button in the calibration menu will restore the device calibration to factory
default. With the heating block NANOCOLOR
can be selected in the two menus
Press the key to start the selected program. The determined temperature deviations are
displayed in different colors depending on the deviation.

A report is stored in the device for both temperature testing and calibration. This report can be
output using the software supplied (see Data Export).
