Calipers

Calipers are precise measuring devices, not tools. Keep them in the case when you are not using them and don't try to pry anything with them. There are digital and manual calipers (venier calipers). We'll start with digital.

Clean off the jaws and zero it.

4 places to get measurements. Flat part of jaws, sharp part of jaws, jaws for internal measurements, part that sticks out base.

Treat your calipers well, do not bend  them or damage the jaws.

Venier calpiers work by lining up the decimal and adding this, will show image and calculation
