REPLACING THE COATING HOLDER

8.3.1
If the coating is faulty or damaged, then a new coating holder must be placed on the sensor. The
instructions for replacing the coating are given below.
1. Remove the sensor from the mounting plate and place it on a level surface so that it cannot roll
onto the floor.
2. Use a 10mm open or closed ended spanner to
unscrew the coating holder from the measuring
head.
3. Use a brush or a small screwdriver to remove any
glue or dirt from the screw thread around the light
guide. Do not damage the light guide.
