Question

dial indicator is an analog gage. (True or false)

A height gage should be used on a wooden surface for best measurement results. (True or false)

What is the name of the type of error where two scales are not in the same plane?

When using a test indicator, it is recommended to allow no more than what angle between the item being measured and the stylus?

Answer 1

a) True. a dial indiactor is an analog gage because it measures small distances, which is an analogous signal.

b) False. a manual gage needs to be set up on a zero refernece plane. it is advised to set it up on granite surface.

c) when the two scales are not in one plane, error is called parallax error. if this error is present, then its reading depends upon the angle at which the observer sets his own eyes.

d) to reduce the cosine error, it is recommended to keep the angle below 20 degrees
