Important hints prior to using the Multimar 25 EWR

• The measuring instrument may only be used for its intended purpose. For damages
caused by other usage or as a result of the incorrect application of this measuring

• In order to ensure a long use of this caliper, any contamination on the caliper must be
removed immediately after completion of usage. This can be done with a dry cloth.
Subsequently, to conserve the metal components, these should be lightly smeared with
slushing oil.

• Protect the data output opening with the respective cover when not in use.

• Clean a dirty housing with a dry, soft cloth. Remove heavy soiling with a cloth wetted with
a neutral reacting solvent. Volatile organic solvents like thinners are not to be used, as
these liquids can damage the housing.
