| Reasons for Abnormal Measurement Results and Solutions When Using the 5Z 14N Probe with the iThick - 7000 Ultrasonic Thickness Gauge ●During the measurement work with the iThick - 7000 ultrasonic thickness gauge, some users reported inaccurate measurement results when using the 5Z 14N probe to measure alloy blocks of different thicknesses. This problem has caused a lot of troubles in practical operations. In the process of use, customers found that when using the 5Z 14N probe to measure alloy blocks with thicknesses of 25 mm, 18.75 mm, and 12.5 mm respectively, the measurement results were consistently lower. Conversely, when measuring an alloy block with a thickness of 6.25 mm, the result was higher than the actual value. This abnormal situation seriously affects the reliability of the measurement data and may have an impact on the quality control and production decision - making processes of related products. ●Through in - depth research and analysis, we have identified the causes of these problems and proposed targeted solutions. The 5Z 14N probe is a single - crystal probe. Incorrect configuration of the probe type in the instrument settings can lead to deviations in the measurement results. It should be set to the single - crystal probe type. If it is wrongly set to the double - crystal probe type, the measurement principles and calculation methods of the instrument will be incorrect, resulting in inaccurate measurement results. ●In addition, the settings of the rectification mode and the measurement mode are also crucial. The rectification mode should be adjusted to the radio - frequency mode, and the measurement mode should be set to the E - E mode. An incorrect rectification mode will lead to deviations in signal processing, thus affecting the accuracy of the measurement results. Incorrect setting of the measurement mode will make the instrument unable to use the correct algorithm to calculate the thickness, also resulting in abnormal measurement data. Regarding the specific parameter settings of the instrument, the probe selection must be set to the 5Z 14N type. At the same time, the filter should be set to 0, the filter frequency to 5 MHz, the voltage to 25 V, and the pulse width to 100 ns. Only when each parameter is set accurately can the instrument operate normally and ensure accurate and reliable measurement results. ●Moreover, the measurement range of the 5Z 14N probe is 3 - 1600 mm. When measuring overly thin workpieces, due to the propagation characteristics of ultrasonic waves, a double - echo phenomenon will occur. This will cause the instrument to miscalculate the distance between the two echoes as the thickness of the workpiece, making the measured value twice the actual value, so the measurement result appears larger. ●In conclusion, when abnormal measurement results occur when using the iThick - 7000 ultrasonic thickness gauge with the 5Z 14N probe, adjusting according to the correct setting methods described above can solve the problem of inaccurate measurement results. This ensures the smooth progress of the measurement work and provides reliable data support for production and quality inspection. In daily use, operators should also strictly follow the operation specifications and parameter requirements of the instrument for setting and measurement to avoid measurement errors caused by improper settings. |
