The adjustment of weighing and counting of electronic scales is usually done through the adjustment buttons or adjustment programs on the scales. Different electronic scales may have different adjustment methods, but generally it can be done as follows: remove all the items on the scale to ensure that the scale surface is clean, and then press the power button to open the electronic scale.
Safe. Remove items from the scale, press the zero key, wait for the screen to display 0.00, and then proceed to the next step after ensuring the screen is stable. Turn on counting mode. On the screen, press the "Unit" button until "PCS" (short for number of pieces) is displayed on the screen.
Put the items to be weighed on the scale and wait for a few seconds until a stable number is displayed on the scale. Press the counting button on the scale or select the counting adjustment program, and then adjust according to the instructions of the electronic scale or the instructions on the screen. You need to enter the quantity or weight of the item, or adjust it according to the instructions in the manual.
After the adjustment is completed, remove the items to be weighed from the scale, and then turn off the power of the electronic scale.
Electronic scales belong to measuring instruments. According to the provisions of the metrology law, all measuring instruments must be verified once a year. It is a weighing instrument and a tool for measuring mass by Hooke's law or the principle of force lever balance. According to the structural principle, it can be divided into three categories: mechanical balance, electronic balance and electromechanical combination balance.
The electronic balance is mainly composed of three parts: weighing plate bearing system, weighing body, lever force transmission system, force transmission system, sensor and dial indicator system, and electronic display instrument. When an object is placed on the scale, pressure is applied to the sensor, which deforms and changes the impedance. At the same time, the change of excitation voltage is used to output an analog change signal.
The signal is amplified by the amplifier circuit and output to the AD converter. Converted into digital signal, which is convenient for processing and output to CPU for operation control. The CPU outputs the results to the display according to keyboard commands and programs. Until this result is displayed.
