Page 7: Basic Safety Notes
Every person who is responsible for the installation, start-up or operation of the device must have read and understood the operating manual and, in particular, the safety instructions. If you still have questions after reading this operating manual, please contact PRIMES or your supplier for your own safety. - Page 8 The radiation is not absorbed by the FocusMonitor itsself. A suitable absorber must be used for this purpose. Suitable PRIMES laser power meters can be found in chapter 7.2.5 „Connecting a FM+ to a laser power meter“ on page 23. When working with the device, people in the hazardous area must protect themselves by taking the following protective measures.
- Page 9 FocusMonitor FM+ Necessary safety measures DANGER Serious eye or skin injury due to laser radiation The device measures direct laser radiation, but does not emit any radiation itself. However, during the measurement the laser beam is reflected from the rotating measuring tip. This produces scattered or directed reflection of the laser beam (laser class 4).
