2.7.2 Cleaning the calibration sphere
NOTICE
Risk of incorrect calibration data caused by contamination
Contamination on the calibration sphere may reduce the data quality.
• Do not touch the calibration sphere.
• If contamination is present, clean the calibration sphere before calibration.
• Do not use solvents or cleaners; they may damage the calibration sphere.
NOTICE
Possible damage to the calibration sphere when cleaning
The calibration sphere may be damaged if it comes into contact with other objects, e.g. when placed on a table.
Vigorous rubbing when cleaning may damage the surface, which will affect the data quality.
• Avoid contact with other objects.
• Hold the calibration sphere only by the shaft when cleaning.
• Only rub gently when cleaning.
Removing minor contaminants
1. Hold the calibration sphere by the shaft with one hand.
2. Carefully wipe the calibration sphere using only light pressure with a clean, soft, lint-free micro-fibre cloth.
