Three coordinate measuring instruments can be divided into manual three coordinate measuring instruments and automatic three coordinate measuring instruments according to their operation methods. Moreover, each type of three coordinate measuring instrument has a different series, and the use methods of different series of three coordinate measuring instruments are different, so it is indeed impossible to use a specific method to answer how to use three coordinate measuring instruments. Below, some common operation methods of different types of three coordinate measuring instruments are summarized as follows:

1. Preparation before measurement:

A. Check whether the air bearing pressure is sufficient

B. Install the workpiece

2. Probe selection and installation

A. Install a suitable probe onto the Z bearing adapter

B. Check whether the Z-axis will automatically slide down (otherwise, adjust the red pressure balance adjusting valve)

3. Measurement operation

A. Turn on the processor power supply

B. Turn on the printer switch

C. Refer to the operation manual and select the command for the desired function

4. Precautions after completion

A. After moving the Z axis to the original position, lock it

B. Move the b, X, and Y axes to the center and lock them

C. Turn off the power supply and pressure valve

D. Remove the probe

E. Proper maintenance
