• Due to the semiconductor in circuit, it is
necessary to use a specified tester for
accurate testing. Use of an improper
tester in an improper range may give
false readings.
• Use a YF-3501 Electric Tester.
• In this table, “Needle swings then
returns” indicates that there is a charging
current applied to a condenser. The needle
will then remain at “∞” unless the
condenser is discharged.
