Important notes for accurate testing
Please read the following instructions carefully because these must be
strictly observed to ensure accurate measurements:
Before inserting the cuvette into the sampling chamber please ensure that
the cuvette is absolutely dry and clean, that there is no soiling by
!
fingerprints etc., so that the light ray transmitted by the device for testing is
not refracted or blocked. It is best to wipe the outside of the cuvette with a
clean and dry cloth before inserting it.
The cuvette lid, the cuvette itself and the stirring rod (if used) must be
!
clean, to ensure that the samples to be tested are not contaminated by
dirt, residues or remaining reagents of a previous test.
!
Never clean cuvette, lid or stirring rod with a detergent as these will leave
residues and could influence any subsequent tests.
It is best to always use the same cuvette for any single parameter and to
!
mark the cuvette on the outside on the bottom with a waterproof marker
accordingly for this particular parameter.
The cuvette must also be free of any scratches as these would divert the
!
light ray transmitted during the test. Replace any scratched or damaged
cuvettes with new ones.
!
Make sure that you use only photometer grade reagents (PL range and
Photometer tablets). Using RAPID reagents will lead to incorrect results!
!
Check before each test run that the reagents used have not exceeded
their best before date.
Always keep the sampling chamber (where the cuvette is inserted) clean.
On the left and right inside of the chamber you will see an opening and
!
behind that a transparent plastic pane. The LED and the sensor are
located behind these. Both panes must be dry and clean.
Any soiling must be cleaned according to A-3 in these instructions.
The measurement must be performed in a radiation-free environment
!
which is not electromagnetically influenced. Keep mobile phones and
radio devices away during sampling.
Some reagents are classified as hazardous materials. These are identified
as such on the packaging. In addition you can download safety
specifications for the reagents offered by PrimeLab from the website
!
www.primelab.org.
Always adhere to the safety instructions on the packaging and in the
safety specifications to prevent damages to yourself, the PrimeLab device
and the environment.
!
NEVER touch reagents with your fingers, pour them directly from the
container into the water sample!
!
Always close liquid reagent containers immediately after use.
Always ensure uniform drop sizes are used.
Air bubbles on the inside of the cuvette wall will result in incorrect
!
measurements!
If there are any bubbles carefully shake the cuvette to release these.
