The calibration files are stored on the QuantStudio™ instrument itself; therefore, when you need to perform a new calibration, you will have to delete the old calibration files. From the instrument console, go to the QuantStudio™ instrument touchscreen and select ‘Collect Results’. You should then see a list of files stored on the instrument. Manually select a calibration file such as “Fast-96-cal”, and press the ‘Delete’ button to remove the old calibration file. Occasionally, users cannot delete the file off the instrument and may encounter this error: “Some experiments did not collect results therefore cannot be deleted.”. In these situations, launch the software, go to ‘maintenance’, manage files, and download the calibration file. The status of the experiment should be displayed as ‘complete’. Next, delete the old calibration file and rerun the calibration.
This error can occur due to allocation of the computer’s virtual memory. If you see this message, try the following:
- Click ‘OK’ to the error, close any unnecessary programs, and re-launch the software (you may have to do this several times).
- Using the Task Manager (Control+Alt+Delete), look for a process called ‘javaw.exe’. Select this line and end the process. Then re-launch the software.
After launching the QuantStudio™ software, go to the Maintenance Manager. Check if the QuantStudio™ system icon is present in the “On the Network” window. If not, click on the ‘Refresh’ button to the left of ‘Remove from My Instruments’. If you still do not see the QuantStudio™ system icon for the following reasons:
- There is an icon but you cannot add it into the "My Instruments" area
- There is a red “X” on the instrument
- A message says "Disconnected" at the bottom of the window with a red “X” in it
then you will need to add the Instrument into the ‘My Instruments’ area. Click on the wrench icon in the upper right-hand corner of the icon as pictured below. You may get a message that says the firmware is older than the one you're trying to run. If appropriate, choose to download the new firmware and let it progress to finish. Do not turn off the instrument during this update. After the firmware update is completed, restart the instrument and check for the QuantStudio™system icon in ‘On the Network’ area.
Please uncheck and check the “Data Collection” camera icon in the Run Method, and the “Start Run” button should now be active again.
