Installation Notes

Thickness gages require no installation and are used as a handheld measurement tool. Always power down and de-energize equipment before inserting any gage blade near moving parts or electrical components. Select the appropriate blade by stepping up from the thinnest blade until light drag is felt — do not force blades into clearances. Handle plastic blades with care to avoid bending or cracking, which can affect measurement accuracy.
