Abstract

The invention provides an electronic scale with adjustable measurement accuracy. The electronic scale comprises a controller, a digital display, a first weighing sensor and a second weighing sensor, wherein the digital display, the first weighing sensor and the second weighing sensor are connected with the controller, the measurement accuracy of the first weighing sensor is lower than the measurement accuracy of the second weighing sensor, the digital display comprises three seven-segment nixie tubes, a light-emitting diode is arranged between each two adjacent seven-segment nixie tubes and isused for displaying a decimal point, the controller employs the first weighing sensor and the second weighing sensor to weigh commodity placed on a weighing table and judges whether decade before thedecimal point in weight information detected by the second weighing sensor is zero or not, if yes, a first light-emitting diode from left to right is controlled to be turned on, the weight information detected by the second weighing sensor is displayed on each seven-segment nixie tube of the digital display, otherwise a second light-emitting diode from left to right is controlled to be turned on,and the weight information detected by the first weighing sensor is displayed on the digital display.

Description

technical field [0001] The invention belongs to the field of electronic scales, and in particular relates to an electronic scale with adjustable measurement accuracy. Background technique [0002] The electronic scale usually includes a controller, a digital display and a load cell, which mainly uses the load cell to weigh the goods placed on the weighing platform, and uses the digital display to display the weighed weight. However, in some scenarios, the digital display is limited by its location, and only a small number of seven-segment digital tubes can be set, which makes the digital display unable to fully display all the data within the range of the load cell. For example, the measurement accuracy of the load cell is two digits before the decimal point and two digits after the decimal point. If the digital display only has three seven-segment digital tubes, it can only measure one digit before the decimal point and One digit after the decimal point is displayed. It c...
