8.1.2 Definition of ‘Overflow’
If the result of the absorbance measurement is not within the instrument
specifications (> 4.0 OD) an overflow will occur and the measured OD value of
the respective well will be replaced by ‘Overflow’. This is done by the controlling
software and not by the instrument itself.
8.1.3 Power Failure
In case of power failure the following happens:
Power failure of the instrument, but not of the controlling computer (e.g. computer
connected to uninterruptible power supply system): USB connection between
instrument and computer will be lost. Error message by the controlling software is
created.
Power failure of both instrument and controlling computer: the computer has to
reboot. No measurement data will be available.
