Concentration too low.
The concentration of the sample used is too low for
submicroliter cell measurements using Lid 5 with the
C40. Sample is below the detection limit of the
instrument. Only cuvette measurement may be
possible
Concentration too low. Change to
lid5/lid10/lid50/lid100
The concentration of the sample used is too low for
submicroliter cell measurements with the used lid.
Change to the recommended lid. A new blank is
recommended when changing the dilution lid.
High absorbance at 250-280nm, 280-340nm, 340-
400nm, 400-475nm,475-550nm, 550-625nm, 625-
700nm. Bad Blank or insufficient cleaning.
The warning message is shown when a blank
measurement (NanoVolume) detects an
absorbance greater than 2.3 (10 mm path). The
warning message shows the wavelength range
where the absorbance is appearing. Two things can
cause high absorbance in a blank measurement:
either the blank solution/buffer has an absorbance
in this wavelength range or the pedestal was not
cleaned properly after the last reading. Clean the
pedestal and the mirror in the lid thoroughly and
check the blank solution for absorbance (Use water
for blank and measure the blank buffer as sample).
Implen Folder is Empty
This message is shown on control devices like
tablets and smartphones when no data has been
saved in the control device folder. For Android
tablets and smartphones this folder is always empty.

Instrument connected to control device! Do you
really want to intercept?
This message is shown on the NanoPhotometer

Click on OK and the measurements session is
interrupted and the data are saved in the auto save

Lint residue or bad sample. Please reapply
sample.
Displayed when Air Bubble Recognition is off.
Software has detected either a lint residue or a bad
sample like e.g. a turbid sample. Check sample,
clean the pedestal and mirror in the lid thoroughly
and reapply sample carefully.
Maximum absorbance level at specified
wavelength reached. Calculations may lead to
low/wrong results.
The concentration of the sample used is too high
and exceeds the specified absorbance range.
Maximum absorbance is 330 A (10 mm path) for
nanovolume and 2.65 A for cuvette measurements.
Dilute sample and measure again.
Maximum level exceeded.
This message is shown when for example, too
many dyes or wavelength are added with the Add +
button. It is possible to add up to 20 dyes or
wavelengths.
Measurement currently in progress. Please close
