Mechanical scale: use and maintenance of mechanical scale
Mechanical scale: use and maintenance of mechanical scale
1、 Mechanical scale usage:
When using the mechanical scale, objects should be placed on the load as gently as possible, not violently. And after each use, the parts are removed to avoid blade damage.
If the mechanical platform scale is used continuously, whether the empty scale is balanced after a certain number of times to ensure the accuracy of measurement. In the process of using the mechanical help scale, except for calibrating the empty scale, nothing can be hung on the frame, otherwise the measurement accuracy of the scale will be affected. When using, in order to avoid damaging the scale body of the mechanical scale, it is necessary to pay attention to the large weight of the measured object, which shall not exceed the weighing indication of the mechanical scale.
2、 Precautions before using the mechanical scale:
When using, first pack the inside and outside of the mechanical scale, place it on a flat and hard ground, and four wheels fall to the ground at the same time to prevent it. The tendency affects the measurement. When using the scale, shake the bearing plate to ensure that each blade of the scale is well connected with the knife. At the same time, check whether the measuring rod is deformed. Then, move the weight point ring and measuring rod of the support (move the weight to the "D" position). If it is not balanced, turn the adjusting screw to balance the empty scale.
3、 Maintenance items of mechanical scale:
When the platform scale is used for a long time, each blade and tool carrier ring are subject to certain wear and fatigue, and the accuracy and sensitivity will decrease each other. Therefore, the mechanical scale must be checked and calibrated regularly. Generally, it should be overhauled in the second half of the year or once a year, and the weight should be calibrated at least once a year.
The collimator shall be kept dry and clean at all times to prevent estimated liquid substances and dirt from remaining in the collimating frame and tool holder. The lifting ring of the scale should always be kept clean so as not to affect the sensitivity (attention should also be paid to the addition of the weight to avoid losing the original accuracy).
The weight shall be kept intact and shall not be unloaded at will.
During transportation, avoid collision. Never let the lever lift the measuring lever, otherwise the scale body and parts will be damaged, the measuring lever will be deformed, and the accuracy of the mechanical scale will be affected.
The mechanical oxide skin shall not be placed in the open air and shall not be placed together with corrosive articles to avoid the corrosion of components affecting the service life.
