PROBLEM TO BE SOLVED: To provide a zero point adjusting method and a zero point adjusting device for a measuring instrument, which shortens an adjusting time to adjust a zero point. SOLUTION: An adjusting level is calculated based on a zero point data N of an output from a sensor 1, an adjusting objective point N2 in an adjusting range, and an amount of variation ΔN in which an adjusting level changes by a variation of a step. Zero point data N can be set to the objective point N2 at a time by switching the port output state by a switching means 6, so that a relation between resistances R1-RN in an adjusting circuit 5, which corresponds to the adjusting level that shows a degree of an adjusting amount size referring a port adjusting table of a port adjusting table means 7, and a port output state of a microcomputer 4 is formed. As a result, an adjusting time to adjust a zero point can be shortened. |
