In older versions of firmware, the instrument shut down after experiencing a fatal error. In this case, the instrument’s memory is usually full. Make sure you have backed up any important measurements to a computer with the USB connection. Switch the instrument on, and in the menu, select “Delete All Batches”.
If this does not resolve the issue, the instrument will require repair with an accredited service centre.
You can contact an accredited service centre for details about whether there is a firmware upgrade available for your instrument.
