​The operation of electronic crane scales should be done according to certain rules

The operation of electronic crane scales should be done according to certain rules
 Follow certain procedures, so as to better complete the operation of electronic crane scales, let's understand:
 1.  Press the "on/off" button of the meter. After the welcome screen, the meter enters the measuring and indicating interface.
 See if the scale is active. Under normal circumstances, after the instrument is turned on, the weighing body is automatically activated, and the instrument can immediately receive the weight signal from the weighing body. When the instrument is turned on, the weight signal cannot be received, which can be solved according to the following steps. *, confirm the weighing body in the remote range of the instrument, if the distance is too far, the instrument is placed relatively low, weighing will not receive the starting signal of the  instrument, adjust the distance, and then re-open the instrument, see whether the activation of the weighing body.
 2.  Confirm whether the weight has been seriously underpowered. Open the small door to replace the battery and try again.1. Press the "start" button. Before weighing, print the title once and check whether the title time is consistent with the current time. If the time is inconsistent, it can be solved by setting time and setting date.2. Press the "tired" button. Eliminate the accumulated and stored original data (or press the "total accumulated" button to clear all stored data).
 3.  The cargo category can be set as required. Press "category" and enter the category number to set the corresponding cargo category.
 4.  Lift the goods off the ground. When the number is stable, press the print button to record the weighing data and place the goods in the designated place.
 5.  End of work. Confirm that the weighing body battery does not need to be charged, and is ready to continue to use in a short time, directly close the meter, otherwise, take out the weighing body battery.
 How to do the routine inspection of electronic crane scales

1. Measurement performance verification

Before metrological performance verification, the load should be preloaded to the maximum scale or the maximum safety load, but attention should be paid to avoid overload of crane scale sensor. 

 2. Zero test

 A scale without zero tracking device or automatic zero setting
 So in the operation of the electronic crane scale should be strictly in accordance with the above method.
 Second, with the lifting machinery safety standards to examine the electronic crane scale1, the design of electronic crane scale mechanical design can be divided into structural design and strength design, both are very important to safety. Here I would like to say more about structural design. There are many structural forms of electronic crane scales. This paper can only choose two common forms to analyze and compare. Divided by the force mode of the sensor.
 The first type of structure: the sensor is under tension, for example, s-type sensor, LN pull sensor.
 The second type of structure: sensor pressure, such as the use of torsional ring sensor, hub-and-spoke sensor.
