# Maintenance and Cleaning

- Check the measuring tool before each use. If the measuring tool is visibly damaged or parts have become loose inside the measuring tool, safe function can no longer be ensured.

Always keep the measuring tool clean and dry to ensure optimum, safe operation.

Never immerse the measuring tool in water or other liquids.

Wipe off any dirt using a dry, soft cloth. Do not use any detergents or solvents.

Do not remove the contact pads (18) on the rear side of the measuring tool.

Only store and transport the measuring tool in the protective bag provided.
