Abstract
An adjusting apparatus sets a designated value of a current source circuit to be a predetermined value, and causes discharging of a capacitor to end by switching a switch to a discharging side when the capacitor is not being charged by current output from a switching power source circuit. After the discharging of the capacitor ends and the designated value is set, the adjusting apparatus causes the capacitor to be charged by switching the switch to a charging side. The adjusting apparatus further measures a time period from the time when the switch is switched to the charging side until an electric potential difference of the capacitor exceeds a threshold value. Based on the measured time period and the predetermined value, the adjusting apparatus calculates the designated value such that the measured time period is a predetermined time period.
