If a higher degree of accuracy verification is necessary, it is recommended to use a fan to blow air onto the sensor so as to minimize temperature variations.   When you have familiarized yourself with the operation of the viscometer and verified proper performance, disconnect the power, remove the piston, and clean both piston and sensor with an alcohol-based solvent or a standard degreaser. Reinsert the piston and secure the flow deflector (if present) before use. Contact [sales@cambridgeviscosity.com](mailto:sales@cambridgeviscosity.com) with any questions.
