What Is The Proper Way To Read Height Gages?

Read height gages

Height gages allow a machine operator to measure the depth of an object with pin-point
accuracy. These gages differ immensely from model to model but most have the
same basic structure. They consist of an arm that is usually in contact with
the object being measured and a measuring unit that moves up and down the
scale. Height gages typically measure vertical spaces but can also measure
other dimensions such as internal and external diameters. Ever wondered about
the proper way to read height gages? Read on to find out more:

Vernier Height Gages

first step when using this kind of height gage is to lock the arm into position
after placing it at the top of the object being measured. When this is done,
you need to then find the ‘zero” on the vernier scale that goes along with the
moving part on the scale. Look at the number on the upright shaft that falls
across the zero marking. Take note of this number as it is the first portion of
your measurement. When this is done, look at the numbered line on the vertical
scale that best aligns with a line on the vertical shaft. This number becomes
your final portion of measurement. The final step is to combine the zero
measurements with the best-aligned measurement to get the final height
measurement of the object you are measuring.

Dial Height Gages

with positioning that arm in place at the top of the object that you want to
measure. When this is done, take note of the last number located beneath the
measuring equipment on the shaft. These numbers are likely to be in increments
of 0.1 inches. Take note of the number that the needle is indicating on the
dial face. The final step is to combine the measurement that you took on the
vertical shaft with the measurement that you noted from the dial face. The
combined number that you get represents that height of the object that you are

Digital Height Gages

taking measurements using this type of height gage, place the arm in position
at the top of the object that you wish to measure. When this is done, find the
digital display on the height gage and take note of the number that is shown on
the display. This number is the height of the object that you are measuring.
With digital height gages, you do not have to take the ‘zero’ setting as this is automatically
set by the gage when you switch it on. For this reason, digital height gages
are very popular as they can give readings much faster than the other two. This
ability is critical in a manufacturing process where the quality control
officers have to randomly test samples from the production line without slowing
down the production process.
