Should I use it?
This high precision measuring instrument is very sensitive and isn't very versatile or practical compared to a caliper. The upside to this tool is its precision, up to 1/1000 of a millimeter depending on the specific model. The downsides are the small measuring range (25mm max), the high cost and it takes a lot of time to screw it open so depending on what your measuring it usually doesn't make sens to use this tool. Mostly it is used to measure if the thickness of s.t. is consistent or to take the exact diameter of a turned peace to make adjustments.
How to use it
Place the object you want to measure between the anvil and spindle and turn the milled knob til the spindle and anvil lightly touch the object. Do not over tighten the spindle. To not damage the spindle and or get distorted readings use don't turn on the spindle directly rather use the milled knob. It has a constant abound of slack and will therefore not allow you to over tighten it. Newer models have a ratchet to allow for even more precision.
