FAQs
What is the primary use of an external spring caliper?
External spring calipers are used to measure or transfer external dimensions, such as the diameter of a round object or the distance between two external points.
How do I adjust the calipers accurately?
Use the centrally located adjustment screw. Turn it slowly to open or close the jaws to your desired measurement, ensuring a smooth and precise action.
Can these calipers be used for internal measurements?
No, these are external spring calipers and are designed specifically for measuring outside dimensions. Internal measurements require internal calipers.
How do I prevent rust on my calipers?
After cleaning, apply a light coating of machine oil to the steel surfaces, especially before storing them for extended periods or in damp conditions.
What is the measurement range of this caliper?
This specific model measures up to 100mm (approximately 4 inches).
Are the points replaceable?
The points are treated for durability but are not designed to be user-replaceable. If damaged, professional sharpening is recommended.
Troubleshooting
Calipers feel stiff or jerky
Ensure the adjustment screw is clean and lightly lubricated. Check for any debris caught in the spring mechanism.
Points are not aligned or sharp
Gently clean the points with a fine abrasive cloth. If significantly damaged, professional sharpening may be required.
Rust appears on the steel finish
Clean the rusted areas with a fine steel wool or abrasive pad. Apply a light machine oil to all steel surfaces and wipe off any excess.
