NITIALIZATION TEST
The NanoPhotometer
®
initialization test is performed automatically every time the instrument
is powered on. If the instrument passes the initialization test the home screen is shown. If
the instrument does not pass the test, a message window will appear explaining the reason
for the failed test along with the recommended solution. If the ok button is selected, the
window is closed and the home screen will be shown. Initialization failed will be displayed on
top of all method screens. If the initialization test fails please contact the Implen Support
Team.
M
ESSAGES
The software gives three different kind of messages: confirmation (green), warning (yellow)
and alert (red)
Confirmation messages are shown e.g. after the initialization test has passed successfully or
if files or folders are copied or moved successfully. These messages are self-explaining and
not listed in the user manual.

Air bubble, lint residue or bad sample. Please
reapply sample.
Air bubble recognition is on and has detected either
an air bubble, lint residue or a bad sample like e.g. a
turbid sample. Check sample, clean the sample
window on pedestal and mirror in the lid arm
thoroughly and reapply sample carefully. To avoid
air bubbles apply sample by reverse pipetting.

lid10/lid50/lid100/lid250
The concentration of the sample used is too high for
submicroliter cell measurements with the utilized lid.
Change to the recommended lid. A new blank is
recommended when changing the dilution lid.
Concentration too high. Dilute sample.
The concentration of the sample is too high for
submicroliter cell measurements using Lid 250 with
the C40. Sample concentration is above the
detection limit of the instrument. Dilute sample
manually to measure within the detection range of
the instrument.
