Evey Weighing scale either electronic or analytical needs calibration. First of all you need a stander Weight i.e 10 kg or 20 kg. Place this standard weight on the platform of the scale and take the reading. If reading is same as standard weight then scale is OK. Please place standard weight at platform at least three times. If the reading is not as per standard weight , then you have follow the calibration procedure. This calibration method written in manual of Weighing Scale. Otherwise you have to contact Weighing Scale dealer or company. Www.mughalwazan.com
A weighing scale is put to good use to assess the weight of a particular material. The method adopted for calibrating an electronic weighing scale includes the sampling of the output of the scale a predetermined number of times. This is done to generate a number of average readings for the particular weight that is placed on the scale. The method compares two successive average readings and selects one of the average reading that is identified within a predetermined weight of the previous average reading. This results in a comparison of the digital signals sampled, representing the selected average reading with the set plurality of settable switches. Each switch position represents a binary bit and displays on a display, the switch settings which highlight the selected average reading of the output. The operator, in response to instructions appearing on the display, then places a weight on the scale, sets one of the switches of the settable switches and sets the switches in response to the instructions displayed. The display helps to store the selected average reading in the settable switches. The method is repeated for a second weight. The industry, weight of the materials and the application determine the calibration of a weighing scale.
