General measurement

1, at a point with the probe for two thickness measurement, in two measurements of the probe segment surface to 90 degrees each other, take the smaller value for the measured workpiece thickness value.

2, 30mm multi-point measurement method: when the measurement value is not stable, with a measurement point as the center, in the diameter of about 30mm circle for several measurements, take the minimum value for the thickness of the measured workpiece.

Precise measurement

The number of measurements is increased around the specified measurement point, and the thickness change is indicated by an isopath.

Continuous measurement method

Use a single point measurement method along the designated route continuous measurement, the interval is not greater than 5mm.

Grid method

Draw a grid on the designated area and measure the thickness by point. This method is widely used in corrosion monitoring of high pressure equipment and stainless steel lining.以上翻译结果来自有道神经网络翻译（YNMT）· 通用领域
