Precautions
•
Maintenance & Cleaning
Before use, thoroughly remove oil, dust and dirt from the entire surface of the dial caliper. Be sure not to damage the measuring and
reference faces.
•
Zero Point Confirmation
Before taking a measurement, clean and close the jaws and check that the dial needle points to "0" on the dial face.
•
During Use
Properly close the caliper on the workpiece. Do not allow dirt, chips, etc., to enter the rack. Otherwise, the rack and pinion could be seriously
damaged, resulting in reduced accuracy and improper zero adjustment.
