Abstract

The invention discloses a method for correcting the northing accuracy of an electronic compass. The method for correcting the northing accuracy of the electronic compass includes: step 1, fixing the electronic compass in the normal working area of ​​the system electrical appliance where it is located, and connecting the electronic compass and the system electrical appliance to Normal work; step 2, perform north accuracy correction on the electronic compass. The method for correcting the northing accuracy of the electronic compass overcomes the problem that the accuracy of the electronic compass in the prior art will decrease when it is used as an accessory in a certain electrical environment, and realizes the accuracy adjustment of the electronic compass.

Description

technical field [0001] The invention relates to the field of correcting the northing accuracy of an electronic compass, in particular to a method for correcting the northing accuracy of an electronic compass. Background technique [0002] The electronic compass in the present invention refers to an electronic device with north-pointing performance, and the north-pointing performance of the electronic device is easily affected by the surrounding electrical environment. At present, most of the electronic compasses popular in the market, when they are used as an accessory in a certain electrical environment (for example, the present invention will take the electronic compass as a north pointing accessory of a display module as an example), indicate In this case, how to ensure the accuracy of the north performance of the electronic compass. Contents of the invention [0003] The purpose of the present invention is to provide a method for correcting the northing accuracy of an...
