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.

Common Recommended PracticesMinimal Basic Laser Tracker Field Checks

Basic System Check

Two Face Field Check2F-Measurement Setup:2 @ -40°, separated horizontally by 90°(measurements on the floor)

Check OK ?

Ball Bar Field Check

No

Check OK ?

BB-Measurement Setup:1 @ 1m (3ft)

Intermediate Compensation

Full Compensation

No Yes

IFM Field Check

Check OK ?

IFM Compensation

No

ADM Instrument Field Check

Yes

Check OK ?

ADM Instrument Compensation

System in specification

No Yes

Yes

IFM-Measurement Setup:use of IFM Distance Tool or2 reflector positions at 3m (10ft) in horizonof tracker head

ADM-Measurement Setup:1 @ 3.5m (11ft)1 @ largest working range
