The present invention relates to a master toolkit to test and correct, which is effectively used to test and correct accuracy of a tire electric resistance tester. According to the present invention, the toolkit to test and correct the accuracy of a tire electric resistance tester comprises: a case capable of measuring indoor temperature and indoor humidity; and a standard bar to test and correct, arranged in the case. It is desirable that the number of the standard bars is several. If the number is 6, each standard bar is manufactured as silica and carbon are mixed at 0:100%, 20:80%, 40:60%, 60:40%, 80:20%, and 100:0% of weight% or volume% and are vulcanized. As such, the master toolkit enables a user to know an electric resistance property value of each standard bar in advance. |
