Cleaning
 Disconnect the Analyzer from the power supply before cleaning the Analyzer.
 Make sure that no liquid enters the interior of the Analyzer.
 Make sure the Analyzer is cooled down before cleaning.
 Clean the Analyzer at regular intervals.
 Housing surfaces and the temperature sensor may be
cleaned with a lint-free cloth slightly dampened with water or
a mild cleaning agent.
 Glass surfaces may be cleaned with a commercial glass
cleaner.
 Do not use solvents, harsh chemicals, ammonia or abrasive
cleaning agents.
