Three Point Caliper Gauge
Usage Method
Insert the measuring head of the three-point caliper into the hole being measured, ensuring that the measuring head fully contacts the hole wall.
Slowly rotate the caliper to evenly spread the measuring head inside the hole until it fully adheres to the hole wall.
Read the scale value on the caliper and record the measurement result.
Overview
Preparation
1. Check the caliper: Before use, check whether all components of the three-point caliper are intact, especially the measuring head and indicator.
2. Clean measuring surface: Ensure that the measuring surface of the measured hole and caliper is clean and free of oil stains and impurities to ensure the accuracy of the measurement.
3. Calibrate the caliper: Use a standard ring gauge to calibrate the three-point caliper to ensure its accuracy meets the requirements.
