Electronic crane scale's composition and maintenance
 Electronic crane scale consists of the following eight large parts:
 1.  Tool bearing system: hook, ring, lug, shell;
 2.  Weighing sensor: it is one of the secondary parts of the electronic crane scale. The whole weighing is sensed by it, and the figure corresponding to the weight is displayed through the display.
 3.  Temperature sensor: to compensate the error caused by temperature change of the weighing sensor;
 4,  A/D converter: convert analog signals to digital signals (that is, the number of our rare display)
 5.  Microprocessor: the relevant processing of the electronic crane scale is transmitted to the display through microprocessor processing
 6.  Monitor: the final weight is shown by the monitor after weighing;
 7.  Receiving and transmitting system: for the electronic crane scales that need transmitting and transmitting devices at a long distance, there is no remote control operation
 8.  Power supply: for the direct display electronic crane scale or electronic crane scale of permitted receiving and transmitting type, the battery pack of a certain department is installed as the power supply to ensure the electricity needs of the sensor and display system as well as the receiving and transmitting system. Electronic Maintenance of electronic crane scale master form, four ways a point.
 Now the electronic crane scale develops rapidly, has been widely used. So many friends to take the initiative to understand the knowledge of the electronic crane  scales. So, born a batch of electronic crane scale maintenance master. How to become an electronic crane scale maintenance master?
 (1)  electronic crane scale short circuit and open circuit method
 Short circuit method is a part of the circuit short circuit, then through the electronic crane scale oscilloscope or multimeter test results to judge the fault point. Open circuit method is to open a part of the circuit, and then through the multimeter to measure the resistance, voltage or current to determine the point of failure.
 (2)  electronic crane scale intuitive method
 In  the electronic crane scale of the main circuit board components more, there are many faults due to the occurrence of short circuit, circuit breaking, plug out of bad contact, components pipe Angle welding and other reasons. Therefore, after the failure of the scale, the circuit board should be first checked with the intuitive feeling: sight, hearing, smell, touch and other methods.
 (3)Voltage measurement method of electronic crane scale
 Electronic crane scale through the circuit components, chip each tube Angle of the working voltage measurement and normal value for comparison, the big voltage change is where the fault is.
 (4)Comparison and substitution of electronic crane scales
 In the fault inspection, with the help of the instrument, the electronic crane scale and the scale with fault comparison, can quickly find the fault point. In addition, if the sensor, circuit board, power supply, keyboard and other parts prepared in the work are suspected to be damaged, replace them with the prepared parts, and then observe whether there is any change in the result. If the display is normal, it means there is something wrong with the original components. The comparison and substitution method can quickly and accurately determine the fault point.
