2. Measurement Methods:

The caliper supports four primary measurement methods:

1. External Measurement: Use the outside measuring jaws to measure the external dimensions of an object. Open the jaws, place the object between them, and close until snug. Read the value on the LCD.
2. Internal Measurement: Use the inside measuring jaws to measure the internal dimensions of an object. Insert the jaws into the opening and expand until they touch the inner surfaces. Read the value on the LCD.
3. Step Measurement: Use the step measuring face (the end of the fixed jaw) to measure the height of a step or shoulder. Place the fixed jaw on the higher surface and extend the slider until the end of the moving jaw rests on the lower surface. Read the value.
4. Depth Measurement: Use the depth probe to measure the depth of a hole or recess. Place the end of the main beam on the top surface and extend the depth probe into the hole until it touches the bottom. Read the value.

3. Locking Measurement:

Once a measurement is taken, you can tighten the Locking Screw to hold the slider in place, allowing you to read the value comfortably or transfer the measurement.

4. Automatic Shut-Off:

The caliper features an automatic shut-off function after 5 minutes of inactivity to conserve battery life.

Maintenance

• Cleaning: Wipe the caliper surfaces with a clean, dry, soft cloth after each use. Avoid using solvents or abrasive cleaners, as they can damage the display or measuring surfaces.
• Storage: Store the caliper in its protective case in a dry, clean environment away from direct sunlight and extreme temperatures.
• Battery Care: Recharge the caliper when the battery indicator is low. Avoid fully discharging the battery frequently to prolong its lifespan.
• Calibration: While the caliper is factory calibrated, regular zeroing before each use ensures consistent accuracy. If you suspect significant inaccuracy, professional calibration may be required.
