Stopping the data logging
When all of the straws have been transferred, click on the grey ‘STOP
LOGGING’ button on the user interface. A message box will appear,
confirming that the user wants to stop logging. Click on ‘OK’ to stop logging
(or ‘Cancel’ to continue logging).
The log file is automatically stored as a .csv (comma separated variables) file,
in the folder specified. The default location for the ‘Logged Files’ folder is:
‘C:\Program Files\ Asymptote\ Asymptote Data Logger\’.
To view the log files, locate the appropriate file in Windows Explorer, right
click on it and choose ‘Open With’, selecting ‘Excel’ from the available
options. Alternatively the file may be opened directly from Excel.
The encrypted file (.aef extension) should be saved separately in an audit
folder.
5.10 Restarting the cycle
The freezer must be switched off and switched back on again before another
freezing cycle can run. Switch the freezer off using the ON/OFF switch at the
front of the freezer, leave the lid on and wait for the plate to warm up to room
temperature. Dry the sample plate between runs. Turn the freezer back on and
allow the temperature to stabilise.
For a faster turn around between runs switch the freezer off and then back on
again. Monitor the plate temperature and, when it reaches 10ºC, turn the
freezer back off again for a few minutes. Dry the plate, turn the freezer on
again and wait for the ‘Ready To Load’ light to turn on.
5.11 Cleaning the unit
The freezer unit and sample plate is designed to be easily cleaned and
sterilised. The surface of unit and the sample plate can be wiped down with a
sterile filtered Biocide C wipe. Dry the sample plate thoroughly after
cleaning.
