EXERCISE 41: Demo on usages of Digital height gauge and

applications

Objectives

At the end of this exercise you shall be able to
• identify parts of digital height gauge
• working of digital height gauge
• applications of digital height gauge.

Procedure

A digital height gauge is an electronic measuring tool used for precise determination of heights in machining,
metalworking, woodworking, and various other precision applications. It offers several advantages over traditional
vernier height gauges, making it a popular choice.
• Construction: Digital height gauge typically consist of a sturdy base, a vertical column with a sliding
mechanism, and a measuring foot. The column houses a linear encoder that translates the movement of the
slide into a digital reading displayed on a LCD screen.
• Measurement Range: Digital height gauge come in various ranges, commonly from 0-150mm up to 0-1000mm
or more.
• Resolution: Digital height gauges offer high resolution, typically ranging from 0.01mm (0.0005 inches) to
0.005mm (0.0002 inches), allowing for very precise measurements.
Setting Up:
1 Turn it on and zero the display: Most digital height gauges will have a power button and a zero/set button.
Turn it on, then with the measuring foot (the foot that touches the object you’re measuring) raised, press the
zero/set button. This sets the current position as the zero point for your measurements.
2 Attaching probes (optional): Some gauges allow attaching different probes for specific applications. If your
gauge uses probes and you need one for your measurement, consult the manual for proper attachment.
