What's a calliper for and how do you use it?
Answer:
A calliper is used to measure the distance between two points. You take the tips of the calliper and place them on the points for which the distance is to be measured. Then leaving the distance between the tips in place remove the caliper from the object being measured and read the distance between the points on a ruler.
A calliper or caliper is an instrument that looked like a compass for drawing circles but it has two points. It is used in engineering for taking the measurement from two points and putting it in another spot or against a ruler.
I use to use a pair of calipers to measure very small, precision measurements in my last job. It's like a scale (ruler) on a set of anvils. The anvil on the right side slides up and down the scale as you take the measurement of the item being measured. What you do is put the item being measured in between the 2 anvils. Then you gently push the movable anvil until it gently holds the item between both anvils. There should be either a dial face or a digital face to read the measurement of the item. My calipers were 6" calipers. My digital ones would be capable of measuring from 0 - 6 inches with a tolerance of + or - .0005. My analog dial calipers were also able to hold the same tolerance. Calipers can be absolutely huge. The largest ones I have ever used were capable of measuring 0 - 6 ft.
I don't know, but have you tried checking wikipedia?
