Cleaning the outer glass and the zero-point reflector:
If the device is indicating a contamination value less than approx. 2%, in general no
cleaning work is necessary.
Scratched outer glass
During any cleaning operation there is a risk of scratching the outer glass in the
measuring head. For this reason always take special care when cleaning the optical
surfaces.
First blow then off with oil-free compressed air to remove any abrasive particles. If
necessary then carefully clean them off with a soft non-linting cloth, wetted as
necessary with water and alcohol.
To prevent displacement of the zero point reflector by an automatic contamination
measurement whilst work is being performed on the screws, first bring the device into
zero point measurement mode:
