Height gages are useful instruments when one needs to measure the height of an object. They come in many different forms and modern height gages can also be used to measure internal diameters among other things. Electronic height gages can be very precise and often claim a consistency of ±0.0001in. Height gage measurement typically involves a moving arm with a pointed end that is usually in contact with the object that is being measured. In the old gages, readings were taken off a vertical and calibrated shaft. Modern height gages have a digital display where readings are displayed.
years, digital height gages have become the preferred choice in many machining
shops. They are made with hardened stainless steel and a heavy base. This makes
the instrument stable and ensures that any reading made are accurate. Digital
height gages also come with data ports that allow the machine operator to
transfer data from the gage to a computer. From there, the data can be printed
or stored for later use.

wise to start the process by cleaning the bench from which you are working. Any
objects or particles on the surface can affect the stability of the height gage
and in turn affect the accuracy of the readings. To get the best results from
your height gage, always ensure that the base of the gage is resting flat on
the surface of the workbench.
that is done, dry the sticker on the digital height gage and fix the measuring
arm on the gage after cleaning it. At this point, ensure that all the LCD displays
and controls of the height gage are working flawlessly. You should also clean
the surface of the item you are measuring with a cloth to ensure that there are
no impurities on the surface of the object.
it comes to taking measurements, move the measuring jaw so that it gently
touches the platform surface. If the machine is set correctly, the value on the
display should be zero. If it is not, turn the machine on and off until it is
zero. When this is done, keep the rod against the surface and move the
measuring jaw to the closest reading. When this is done, take the reading on
the LCD screen.
have an object that is above the range of the height gage, raise the base of
the gage and place an even block underneath it. Zero-point becomes the platform
surface and the starting point is the top of the block. In such a case, ensure
that you have preset the height of the block. Remember to clean the jaws and the
unit after measurement before storage. You should also avoid applying electric
current to any part of the unit as this is likely to damage the sensitive
electronics in the unit.
