How to use

To measure external dimensions, place the jaws around the object and slide the movable jaw until it contacts the surfaces, then read the value on the scale. For internal measurements, open the jaws inside the cavity and align them with opposing surfaces before reading the scale. To measure depth, extend the depth rod into the hole or slot and read the scale while keeping the caliper body flat against the reference surface. Ensure the caliper is clean and free of debris for accurate readings and close the jaws gently after use to protect the scale and measuring faces.

Usage recommendations

Store the caliper in a protective pouch or drawer to avoid impacts and contamination. Periodically check the scale alignment and measuring faces for wear; avoid using excessive force when closing jaws. For highest accuracy, use the caliper at ambient temperature and allow the tool and measured parts to reach the same temperature before taking critical measurements.
