Packaging scale price

Packaging scales must go through a series of tests before they are officially put into operation to ensure the effectiveness of the equipment. This includes a color mark compensation test. The focus today is here, let’s see how the packaging scale performs color mark compensation testing?
When performing color mark compensation testing on packaging scales, the use of an oscilloscope is indispensable. First, connect the input terminal of the equipment, and then use the buttons to set the appropriate number of compensation steps. Then, a rising edge level transition is created at the color mark detection input port, which indicates that color mark compensation is required. Finally, an oscilloscope is used to detect a certain number of drive pulses at the stepper motor drive signal port of the main control circuit board. If the high level time of the pulse is the same as the timing time of the timer, it means that the packaging scale control system can correctly Stepper motors send drive pulses.
In fact, to complete the color mark compensation of the packaging scale, it is not only necessary to send drive pulses to the stepper motor, but also to provide it with a direction signal. The next step is to do this work. Use the same method to connect the oscilloscope to the main control circuit board and the pin corresponding to the stepper motor driving direction, and observe the level change of the pin. If what is seen on the oscilloscope is a low-level signal, it means that the packaging scale control system can correctly compensate for the color mark, and our goal has been achieved.
