​Detailed steps of electronic crane scale weighing test

Detailed steps of electronic crane scale weighing test
 Is it right that we buy back the electronic crane scale tester? Of course not. Buying it back is only the first step, and the next step is to understand it, use it and maintain it. Here and you introduce the electronic crane scale weighing detailed steps as follows:
 Detailed steps of weighing test:
 1.  Determine the status of automatic zero setting and zero tracking device, and cross the corresponding box to record.
 2.  Determine at least 10 different load values selected in this test.
 3.  Preloading.
 4.  Record the application, ambient temperature and humidity.
 5.  Find the error of zero or close to zero (10d).
 6.  Add weight, small gradually increase to the maximum scale.
 7.  Record time and ambient temperature.
 8.  Calculate and record error E.
 9.  Determine whether the electronic crane scale through the requirements.
 10.  If the electronic crane scale has more than 20% of the initial zero range of the maximum scale, then to carry out supplementary scale test.
 11.  In the whole process of the electronic crane scale test, it is necessary to regularly carry out range stability test.

 About the correct use method of electronic crane scale.
 1.Before the use of electronic crane scale, should be the corresponding battery into the scale body and handheld device or change the battery, need to tighten the battery clamp lock screw, check whether the battery clamp is firmly fixed on the scale body, and then the crane scale door closed lock, to prevent accidents.
 2.Prevent the electronic crane scale from violent pull (and collision internal many  electronic components, electronic crane scale, such as integrated circuit, quartz crystal, sensors, monitors, etc., when there is intense collision of  electronic crane scale, can damage the components, electronic scale caused by fault, affect accuracy so as to affect the normal use, and other items to prevent scale body collision or falling from high up in the air, instrument to should take put down gently, don't put randomly, to prevent the loss of don't want to, instrument fixed on the crane should be taken when using vibration reduction measures, so as not to affect the reliability.
 3.Banned optional electronic hook scale components, electronic crane scale, normal use don't assemble the parts on the electronic scale, more do not open the sealing mouth of the sensor assembly instrument on the integrated circuit components, such as the necessary repairs, required in under the guidance of relevant technical personnel or have a certain knowledge of maintenance, after in case of failure to expand.
 Structural innovation and application analysis of electronic crane scale
 Load-bearing device, weighing sensor and weighing instrument are three basic components of electronic scale, among which the scientific and rational structure of load-bearing device is an important guarantee of accuracy, stability and reliability of electronic scale. Nowadays, the electronic scale market is becoming more and more internationalized. The improvement and innovation of electronic scale structure are bound to be oriented by the needs of users and market competition.
