Taking Measurements:
1 Lower the measuring foot: Use the slide mechanism, a rack and pinion system with a fine adjustment knob,
to lower the measuring foot towards the object you want to measure.
2 Reaching the reference point: Gently bring the measuring foot down until it just barely touches the surface
referencing from (e.g., a flat surface on workpiece). Often hear a beep or see a change on the display to
indicate contact.
3 Reading the measurement: The current display value represents the distance between the measuring foot
and the reference point established when zeroed the gauge.
Advantages over Vernier Height Gauges:
• Easier to read: Digital display provides clear and unambiguous readings, eliminating the need to interpret
vernier scales.

• Faster measurements: Digital readout allows for quicker measurements compared to vernier gauges.
• Data output: Some models can transmit data to computers for recording or analysis.
• Error reduction: Less prone to human error in reading vernier scales.
Uses of digital height gauge:

• Measuring workpiece heights, thicknesses, and depths.
• Transferring reference heights for marking or machining operations.
• Checking parallelism and perpendicularity.
• Setting tool heights on machines like milling machines or drill presses.
