5.2 Zero Function

The zero function allows you to set a reference point for relative measurements.

• Close the measuring jaws completely and press the ZERO button to set the display to zero. This is recommended before starting any measurement.
• You can also press the ZERO button with the jaws at any position to set that point as zero. This is useful for measuring deviations from a specific reference size.

5.3 Unit Conversion

The caliper can display measurements in millimeters (mm), inches (in), and fractions (F).

• Press the mm/in/F button to cycle through the measurement units.
• The selected unit will be indicated on the LCD display.

5.4 Measurement Methods

The S&F STEAD & FAST Digital Caliper supports four primary measurement methods:

• External Dimensions: Use the large external jaws to measure the outside length or width of an object.
• Internal Dimensions: Use the small internal jaws to measure the inside diameter of holes or grooves.
• Step Measurement: Use the step-measuring faces to measure the height difference between two surfaces.
• Depth Measurement: Extend the depth gauge into a hole or recess to measure its depth.

5.5 Locking Screw

The locking screw at the top of the caliper allows you to fix the slider in position for precise readings or to adjust the sliding resistance. Tighten the screw to lock the jaws, or loosen it to allow free movement.

6. Maintenance

6.1 Cleaning

To maintain accuracy and prolong the life of your caliper:

• Wipe the caliper clean with a dry, soft cloth after each use.
• Avoid using solvents or harsh chemicals, as these can damage the display or finish.
• Ensure no debris or dust accumulates in the slider mechanism.

6.2 Storage

Always store the digital caliper in its provided hard plastic case when not in use. This protects it from impacts, dust, and moisture, preserving its accuracy and condition.

6.3 Battery Replacement

Refer to section 4.2 for detailed instructions on replacing the CR2032 battery.

7. Troubleshooting

• Display is blank or dim: Check battery installation. Replace the CR2032 battery if necessary (refer to section 4.2).
• Inaccurate readings: Ensure the jaws are clean and free of debris. Perform a zero reset with the jaws closed. Check if the locking screw is too tight or loose, affecting smooth movement.
• Slider movement is stiff: Clean the caliper bar thoroughly. Apply a very small amount of light machine oil if necessary, wiping off any excess. Adjust the locking screw tension.
• Display shows 'L' or 'H': This may indicate a low battery ('L') or an error. Replace the battery. If the issue persists, contact customer support.
