Dear user, hello! Welcome to use the iLeeb - 150 Pen Type Leeb Hardness Tester. This exquisitely designed and highly - performing instrument is sure to provide you with accurate and convenient services in material hardness testing. Next, I will introduce its usage in detail. Before starting to use, we must carry out some necessary preparatory work. First, carefully inspect the appearance of the instrument. Pick up the hardness tester and carefully check whether the casing has any damage, scratches, or deformation. This is not only related to the aesthetics of the instrument, but more importantly, the integrity of the casing directly affects the safety of the internal precision components. If you find any problems , do not use it rashly. Instead, contact our professional customer service team immediately, and they will solve the problem for you properly.Then, pay attention to the display screen. The display screen is the key window for us to obtain measurement data, and it must be clear and flawless. Check for any dead pixels, bright spots, or blurry displays. If there are problems with the display screen  , it may cause you to misread the measurement results, thus affecting your work judgment.After that, focus on checking the impact device. The impact device is one of the core components of the hardness tester and directly determines the accuracy of the measurement.  Carefully observe the impact ball - head. It should be smooth and show no signs of wear. If the impact ball - head has obvious wear, such as pits or deformation, it's like cutting with a dull knife, and the measurement results will surely be inaccurate. At the same time, ensure that the impact rod can move flexibly without any jamming. You can gently push the impact rod to feel whether its movement is smooth. If there is any abnormality, be sure to replace the relevant parts in a timely manner. There is another point that cannot be ignored, and that is the battery level. You can intuitively understand the battery status through the battery indicator on the display screen of the hardness tester. If the battery is low, immediately charge it with the original charger. Imagine that during an important measurement, the work is suddenly interrupted due to a dead battery. How troublesome that would be. Therefore, keeping the battery fully charged is the basis for ensuring the smooth progress of the measurement work.After the preparatory work is completed  , it comes to the selection of appropriate accessories and calibration. According to the specific characteristics of the material to be tested, such as whether the shape is regular or irregular, the thickness is thick or thin, and the surface roughness is large or small, select the appropriate support ring. For example, for materials with a rough surface, in order to ensure the stability of the measurement, a support ring with a large contact area is required; for thin - walled materials, a lightweight and well - fitting support ring should be chosen to avoid damaging the material.After selecting the support ring, install the appropriate impact device. The iLeeb - 150 is usually equipped with a variety of impact devices, such as the D - type and DC - type. Different impact devices are suitable for measuring different hardness ranges and material characteristics. When installing, make sure it is firmly installed. Gently shake it to check for any looseness.  A loose impact device will displace during the measurement, and the measurement results will naturally be inaccurate.Calibration is a crucial step to ensure measurement accuracy. Before formal measurement, the hardness tester must be calibrated using a standard hardness block. The hardness value of the standard hardness block should be close to the hardness range of the material you are going to measure.  Place the hardness tester vertically and steadily on the standard hardness block, start the measurement program, and perform multiple measurements, generally not less than three times. Record each measurement value and then calculate the average. Compare this average with the nominal hardness value of the standard hardness block. If the deviation exceeds the allowable range (usually within ±2%), you need to enter the calibration mode for adjustment according to the instructions in the operation manual. After calibration, don't forget to conduct a measurement verification to ensure that the hardness tester has been calibrated accurately.Once everything is ready  , the measurement operation can be carried out. Press the power button of the hardness tester and wait for the display screen to light up and complete the initialization. During the initialization process, the instrument will automatically check internal circuits, sensors, and other components. When the normal measurement interface appears on the display screen, you can start the next step.According to the nature of the material to be tested and the measurement requirements, select the appropriate measurement mode from the operation menu. Common measurement modes include single - point measurement and continuous measurement. If you only need to measure the hardness of a single point, the single - point measurement mode is sufficient; if you need to quickly obtain the hardness values of multiple points, the continuous measurement mode will be more efficient. Next, select the corresponding hardness scale. The iLeeb - 150 supports a variety of hardness scales, such as Leeb (HL), Brinell (HB), Rockwell (HRA, HRB, HRC), and Vickers (HV). When selecting, it should be based on the type of material and industry - wide standards to ensure that the selection of the hardness scale is accurate, so as to obtain accurate measurement results  .Place the support ring of the hardness tester steadily on the surface of the material to be tested. Be sure to ensure that the support ring is in close contact with the material surface, and the hardness tester should be kept in a vertical state. If the hardness tester is tilted, the measurement results will be as inaccurate as a slanted scale. Press the measurement button, and the impact device starts to work. The impact ball - head will quickly impact the surface of the material to be tested. The internal sensors of the hardness tester will capture the data during the impact process and calculate the hardness value of the material based on the Leeb hardness measurement principle. After the measurement is completed, the hardness value will be clearly displayed on the display screen.  The display screen may also show information such as the measurement sequence number and measurement time. If you need to record the measurement results, you can record them manually or use the storage function of the hardness tester (if available) for saving.In order to improve the reliability of the measurement results, for the same measurement point or the same batch of materials, it is recommended to perform multiple measurements, generally not less than three times. After each measurement, move the hardness tester away from the surface of the material to be tested, and then place it again for the next measurement. This can avoid the surface deformation caused by the previous measurement affecting the subsequent measurement results. Process the data from multiple measurements, and calculate statistical parameters such as the average value, maximum value, and minimum value. By analyzing these data, the hardness uniformity of the material to be tested can be evaluated. If the discreteness of the measurement data is large, it may mean that the material to be tested has internal defects or uneven organizational structure, etc., which requires further analysis and treatment. After the measurement work is completed  , press the power button to turn off the hardness tester. Before turning off, be sure to ensure that all important measurement data have been recorded or saved to avoid data loss.Wipe the casing of the hardness tester with a clean soft cloth to remove dust and stains on the surface  . For stains on the display screen, you can use a special screen cleaner and a soft wiping cloth for cleaning. Be careful not to use rough items to wipe, so as not to scratch the screen.Check the impact device and the support ring. If there is dirt or debris attached, use appropriate tools to clean them. For example, for dirt on the impact ball - head, you can gently wipe it with an alcohol - soaked cotton ball; for debris on the support ring, you can use a small brush to clean it. After cleaning, ensure that the surfaces of the impact device and the support ring are clean and tidy. Store the hardness tester in a dry and ventilated environment, avoiding long - term exposure to humid, high - temperature, or corrosive gas environments. At the same time, avoid the hardness tester from being subjected to severe impacts and vibrations, so as not to damage the internal precision components. Regularly maintain the hardness tester and check whether the various performance indicators of the device are normal. It is recommended to conduct a comprehensive inspection and maintenance of the hardness tester every once in a while (such as every 3 - 6 months), including checking the performance of the battery, the working status of the impact device, the sensitivity of the sensor, etc. Calibrate the hardness tester using a standard hardness block at the specified time interval (usually every 1 - 2 years). The calibration process is the same as the pre - use calibration method. Through calibration, measurement errors that may occur during the long - term use of the hardness tester can be detected and corrected in a timely manner, ensuring the accuracy and reliability of the measurement results.I hope the above instructions can help you master the use of the iLeeb - 150 Pen Type Leeb Hardness Tester.
