MX’er SYSTEM
CDI unit.
Measure the resistance between the
terminals using the electric tester.
.
Testing Range
Use the xKΩ range for the Sanwa Tester.
Use the xKΩ range for the Kowa Tester.
Note: The readings in this table are taken
with a Sanwa Tester.
• 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 Sanwa Electric Tester or Kowa
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.
