Preface

Please read these Operating Instructions before commissioning the
instrument. Keep the manual in a place that is accessible to all users at all
times.

Please assist us to improve these operating instructions, where necessary.

Your suggestions will be appreciated.

All necessary settings are described in this manual. However, if any
difficulties should still arise during start-up, please do not carry out
any unauthorized manipulations. You could endanger your rights
under the instrument warranty!

Please contact the nearest subsidiary or the main factory in such a
case.

Caution

A sudden failure of a measuring cell may lead to excessive or
insufficient dosing of oxygen. This may harm living creatures (fish
in ponds or micro-organisms in wastewater-treatment plants).

Appropriate precautionary measures must therefore be taken in
such a case.
