NOTICE
In this menu, you can trigger direct function controls. If these controls are incorrectly
combined, however, this could damage the analyzer.
►
Using the Service menu requires detailed knowledge of how the analyzer works and operates.
►
Exit the Service menu with the "M" key. All functions will be reset to the delivery state then.
►
When using the manual operation via the Service menu, make sure that chloride containing
sample never gets in contact with reagent R2 in the reactor. Otherwise precipitating silver
chloride can cause film or coating on the optical windows. Measuring errors would be the
consequence.
