Abstract
PURPOSE: To make the time for measurement unnecessary by detecting that a leak current exceeds a preset level to stop the charging operation of a capacitor so that the terminal voltage of the capacitor may be measured.
CONSTITUTION: If a control terminal 15 is under a condition of 0 level logic, a capacitor 4 is discharged. At this time, the operations of the voltage measurement by a voltage measuring circuit 5 is stopped. If the control terminal 15 is placed under the condition of the logic level, the charging operation of the capacitor 4 is started because the operations of a discharge circuit 3 are stopped. If the terminal voltage of the capacitor 4 is so increased that the leak current exceeds a preset level, the output of a comparator circuit 72 is changed to 1 level logic so that a constant current supply circuit 2 is stopped. Simultaneously as this, the output of an inverter 13 is changed into the level logic to measure the voltage. If, now, the control terminal 15 is returned to the 0 level logic, the initial condiction is restored.
