Key Features & Functions

• 4-Way Measurement Capability: Designed to measure:

  1. External Dimensions: Measuring the outside diameter or thickness of objects using the large lower jaws.

  2. Internal Dimensions: Measuring holes, pipes, or inner clearances using the smaller upper jaws.

  3. Depth: Measuring the depth of a hole or recess using the extended depth blade at the tail.

  4. Step Measurements: Measuring height differences or offset steps using the stepped edge.

• Zero / Tare Button: Allows you to reset the display to zero at any position along the slide, making it easy to measure relative differences or tolerances.

• Unit Conversion: Instantly toggles between metric millimeters (mm) and imperial inches (inch) at the touch of a button.

• Auto Power-Off: Automatically shuts down after a period of inactivity (usually 5–8 minutes) to preserve battery life.
