Cleaning the Optics

Contamination in the optical cell may effect the accuracy of
readings and can trigger error messages to be displayed.
Clean optical windows gently with a soft, non-abrasive cloth
dampened with water. Do not use solvents.
Instrument failure due to contamination is not covered by warranty.

Check Standards

Sets of Check Standards for Pooltest Instruments are
available from Palintest. These verify that the instrument
is correctly calibrated and performing correctly.
