remains in the compartment should be wipe off immediately.
Surface clean
The cover of the instrument is with paint. Please use wet towel to wipe off the drips on the
surface immediately. Organic solution is forbidden to be used to clean the cover. Please wipe off
the dirt on the cover timely.
Clean the cuvettes
After every test or after a solution change, the cuvettes should be cleaned carefully, or the
remains on the surface would cause measuring error.
