1. Introduction

In contrast to the Quick Guide, this Reference Handbook provides a complete description ofthe operating principles of the DL50, DL53, DL55 and DL58 Titrators. Its layout has been keptmodular to ensure future supplementation or replacement of individual sections or pages; newtexts carry the date of issue in the footer on every page.

Safety notesMeasures for your personal protection and for operational safety are described in Section 2of the Quick Guide. We strongly advise you to read these. The symbols listed there also appearfor texts in this Reference Handbook which require safety measures.

Keywords usedappears before all texts which refer to an error in the measured value acqui-sition, data storage etc.

Note appears before all texts which contain additional explanations.

Index

The index in Section 13 comprises key words from the Quick Guide and the ReferenceHandbook.

Software versionThe Reference Handbook applies to software version 2.x for all four titrators.

Note: All information concerning automation in this titrator's Reference Handbook relatesto the earlier METTLER TOLEDO Sample changer ST20A. Its name continues toappear in some places. Operation of other METTLER TOLEDO sample changersvia your titrator is described in the corresonding Operating Instructions.

The following pages provide an overview of the menus and commands which are availableunder the menu and auxiliary function keys.
