What is the correct order for digital caliper calibration steps?

The correct sequence for calibrating a digital caliper begins with turning on the caliper display to ensure it is active and responsive. Following this, closing the jaws is essential because it establishes a reference point for the measurement; the jaws should be fully closed to provide an accurate zero reading. Finally, pressing the zero button sets the display to zero, informing the device that the current position (with the jaws closed) is the starting point for any future measurements. This order ensures that the calibration reflects the actual position of the caliper, providing precise measurements thereafter.

Other sequences may not properly establish the initial reference point or could lead to incorrect zeroing, which can result in inaccurate readings during subsequent measurements.
