® photoLab 7100 VIS Safety Safety Safety information 2.1.1 Safety information in the operating manual This operating manual provides important information on the safe operation of the product. Read this operating manual thoroughly and make yourself familiar with the product before putting it into operation or working with it. The operating manual must be kept in the vicinity of the product so you can always find the information you need.
® Safety photoLab 7100 VIS Safe operation 2.2.1 Authorized use The authorized use of the photometer consists exclusively of the carrying out of photometric measurements according to this operating manual. Follow the technical specifications of the cells in chapter 7 T .
® photoLab 7100 VIS Safety Handling of hazardous substances When developing test sets, WTW carefully sees that the tests can be carried out as safely as possible. Some hazards by dangerous substances, however, cannot always be avoided. If self-produced tests or solutions are used, the responsibility concerning any risks caused by those tests or solutions lies with the user (personal respon- sibility).
® Commissioning photoLab 7100 VIS Commissioning General notes on handling ® The photoLab 7100 VIS photometer is an optical precision meter. There- fore, it should always be handled with care, especially in mobile use. Always protect the meter from conditions that could damage the mechanical, optical and electronic components.
® photoLab 7100 VIS Commissioning The original packing is also required for the proper return of the instru- ment if it has to be repaired. Note that damage caused by improper transport voids all warranty claims. 3.2.1 Inserting the buffer batteries The buffer batteries supply the integrated clock while the photometer is switched off.
