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 welcome.

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 on the instrument. You could
endanger your rights under the instrument warranty!

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

When returning modules, assemblies or components, the rules of
EN 100 015 “Protection of electrostatically sensitive components”
must be observed. Use only the appropriate 

ESD

 packaging for

transport.

Please note that we cannot accept any liability for damage caused
by ESD (electrostatic discharge).
