Calibration
Before calibration, carefully clean and dry the instrument. Now add 1-2 drops of distilled water to
the prism. If the light / dark limit is not at 0 % (water line), this must be adjusted via the calibration
screw under the rubber cover, using the screwdriver supplied. The PCE-4582 and PCE 5890
cannot be calibrated with distilled water, a sample solution with a known sugar content (e. g. 70
% sugar solution) should be used.
Note:
Instruments are already calibrated at the factory.
Important notes:
•
The hinged lid and the prism should be kept clean at all costs; dirt will impair the
measuring accuracy.
•
Avoid scratches on the prism and the hinged lid, this also has a negative influence on
the measurement.
•
Do not use any sharp, aggressive cleaning agents for cleaning but only a damp cloth.
Dry the meter well afterwards.
•
Clean the instrument only with a damp cloth, never under water, as this could penetrate
the instrument.
•
Prevent shocks and impacts as this can destroy the optics
•
Store the instrument in a dry place.

Disposal
For the disposal of batteries in the EU, the 2006/66/EC
directive of the European Parliament
applies. Due to the contained pollutants, batteries must not be disposed of as household waste.
They must be given to collection points designed for that purpose.
In order to comply with the EU directive 2012/19/EU we take our devices back. We either re-use
them or give them to a recycling company which disposes of the devices in line with law.
For countries outside the EU, batteries and devices should be disposed of in accordance with
your local waste regulations.
If you have any questions, please contact PCE Instruments.
