Error 111 – Battery Critical
Battery level is critically low and the instrument will
automatically shut down immediately to ensure all data
is written to the memory correctly.
Other more general issues that arise may be as follows:-
Readings are consistently higher than expected
Check the sample cuvette for dirt, scratches and
marks. Turbidity is an optical measurement and will be
adversely affected by unwanted items in the optical
paths.
Index the cuvette using the 'Continuous-Capture'
mode to ensure the most accurate reading position is
selected.
Apply a thin film of silicone oil to the cuvette to 'fill in'
any scratches.
Replace the cuvette with a new, unused cuvette.
Check the calibration using the supplied standards to
ensure no offset has been inadvertently applied.
Recalibrate if necessary.
Readings are consistently lower than expected
Fouling in the optical chamber may prevent the
sources being transmitted with full intensity. The
unique QuadoptiX™ system will prevent this issue
arising in all but the most challenging circumstances.
