Operating Instructions
Turning On/Off
- To Turn On: Press the "ON/OFF" button or simply move the digital unit along the beam.
- To Turn Off: Press the "ON/OFF" button. The caliper will also automatically power off after a period of inactivity.
Zero Setting
The zero point can be set at any position, allowing for incremental measurements.
- Close the measuring jaws completely for absolute zero, or position the jaws at your desired reference point.
- Press the "ZERO" button. The display will show "0.00" or "0.000".
Inch/Millimeter Conversion
To switch between inch and millimeter units:
- Press the "INCH/MM" button. The display will toggle between the two units.
Taking Measurements
- Ensure the caliper is clean and the jaws are free of debris.
- Turn on the caliper and set the zero point as needed.
- Gently open the jaws and position the workpiece between the appropriate measuring surfaces (outside jaws for external dimensions, inside jaws for internal dimensions, or depth rod for depth measurements).
- Close the jaws until they make firm, but not excessive, contact with the workpiece.
- Read the measurement directly from the digital display.

Maintenance
Cleaning
- Regularly clean the measuring surfaces and the beam with a clean, dry, lint-free cloth.
- Avoid using solvents or abrasive cleaners, as these can damage the display or measuring surfaces.
- Keep the digital unit dry. While the caliper is made of stainless steel, the electronic components are not waterproof.
Storage
- Store the caliper in its protective hard plastic case when not in use to prevent damage.
- Store in a dry environment, away from direct sunlight and extreme temperatures.
- Slightly open the jaws before storing to relieve tension on the measuring surfaces.
