​Maintenance of electronic crane scale's charger

Maintenance of electronic crane scale's charger

1. The battery inside the electronic crane scale is only allowed to be charged with the charger provided randomly. It is strictly forbidden to charge the battery with other devices.

2. When the ambient temperature is too low, the working time of nickel-cadmium battery in the scale cannot be guaranteed.

3. If not used, the fully charged battery will discharge itself gradually.

4. In order to achieve the best performance of the battery, it is recommended to charge the battery for at least 12 hours before using the new battery or the battery that has not been used for a long time. The new battery needs several charges and discharges to reach its best performance. New batteries or batteries that have not been used for a long time may cause the charger to indicate that the battery is fully charged prematurely. When you see the indication that the battery is fully charged, you should continue to let the battery charge for a few more hours.

5. When the battery is no longer in use, please use up the battery and store it in a cool, dark and dry place.

6. Avoid the built-in micro printer when using the Cranemate battery.

Electronic crane scale main components, sensors, all instruments and independent production, high precision, reliable performance. Crane scale strictly and fatigue strength testing of tolerance components. Instrumentation, sensors, temperature test, the whole scale, full range calibration precision absolute guarantee. Can be analysis from the aspects of energy conversion, the capacitive transducer is a kind of passive converter, convert the data in the first place, converted into a voltage or current, amplification, processing again.

Electronic crane scale in mechanical quantity, a lot of quantity is closely connected with the degree, such as tensile, compression, expansion, and needs to be measured by length. At the same time, under certain conditions, the dynamics of change is not quickly, change only in a small scope, if you want to accurately measure the slight change, other sensors cannot do, this would require the use of capacitance sensor. Capacitive sensors have been vibration, Angle, displacement, acceleration of mechanical quantity measurement has been widely used, Characteristics, when measuring mechanical quantities with very small changes, this kind of sensor is needed. Its main characteristics are shown in  the following aspects: the measurement range is very large, and the rate of change can sometimes exceed 100%.

Electronic crane scale manufacturing technology for electronic crane scale the influence of mechanical safety is self-evident, mainly reflected in the main load-bearing structure of the forging, heat treatment, mechanical processing, parts of products in a wide range can be welded. Crane scale production enterprise scale is not large, usually often do not have the forging and heat treatment ability. Need to select qualified professional manufacturers, and pay attention to strengthen the crane scale product acceptance link. Here is a special emphasis on the crane scale connection thread processing. Main stress in crane scale structure bearing thread and the stress state of the thread on the straight shank hook is actually pretty close. Straight shank hook in the national standards related to thread And nuts have detailed requirements, including material, hot working, cutting and inspection methods and requirements.
