  2. Common Recommended PracticesMinimal Basic Laser Tracker Field Checks • Assumption • System has been shipped overseas (airplane) • System has been shipped within a country (truck, airplane, car,…) • System has been moved from one to the other plant (truck, car, …) • System has been moved from one to the other working area (put on measurement cart or transportation in white shipping containers “disassembled”, …) Independent of the transportation way, we recommend a basic minimal test procedure. This recommendation is also applicable for daily work. Unterentfelden 2007-07-18, D.Moser -785
