5.1 Verifying the Mastercycler nexus, pro and ep
5.1.1 Overview
The verification program checks the temperature accuracy of the thermoblock.
The Mastercycler heats the thermoblock to 95 °C and then to 35 °C. In the process, the user will
be prompted to measure the temperature in 6 different block positions that are shown on the
display. The verification procedure lasts approx. 30 minutes.
The Mastercycler outputs the measuring results on the display and on a printer or storage
medium.
The CycleManager generates a protocol of the measurement on the monitor. The protocol can be
printed or saved as a text file using the File menu.
The following Mastercyclers save the measuring results on a MultiMediaCard:
•
Mastercycler ep
•
Mastercycler pro
The following Mastercyclers save the measuring results on a USB stick:
•
Mastercycler pro
•
Mastercycler nexus
The Mastercycler must be adjusted if the measured values are outside of the maximum
permissible error.
The maximum permissible errors for the Temperature Verification System USB – Single-channel
and the devices are listed in the technical data.
