  1. Minimal Basic Field Checks for Laser Tracker SystemsDecision Matrix

  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

  3. Common Recommended PracticesMinimal Basic Laser Tracker Field Checks Basic System Check 2F-Measurement Setup:2 @ -40°, separated horizontally by 90°(measurements on the floor) Two Face Field Check No Check OK ? Yes IFM-Measurement Setup:use of IFM Distance Tool or2 reflector positions at 3m (10ft) in horizonof tracker head BB-Measurement Setup:1 @ 1m (3ft) Ball Bar Field Check IFM Field Check No Check OK ? Yes No Check OK ? Yes ADM-Measurement Setup:1 @ 3.5m (11ft)1 @ largest working range ADM Instrument Field Check Full Compensation Intermediate Compensation IFM Compensation No Yes Check OK ?
