2.1.

Assembling the tester.

2.1.1.

Attach the extension probe onto the tester’s probe tip.

2.1.2.

Press fit the signal receiver pad onto the extension probe.

2.2.

How to operate the tester.

2.2.1.

Turn on the tester by turning the rotary switch. To indicate the tester is on, the red and green LEDs rapidly flash alternately, and the tester

emits an ascending beeping sound for a short period. After use, until the tester is turned off, the green LED continues to slowly flash to

indicate the tester is on.

2.2.2.

With the engine running, firmly place the tester’s signal receiver pad against the COP’S body. Make sure the marked side of the pad

is towards the COP, adjust the sensitivity switch until the red and green LEDs flash simultaneously. As the tester relies on a

signal emitted from the COP body, it may be necessary to move the signal receiver pad around until the pad is in a position to pick up the

strongest signal.

note:

The strength of signal that each car produces is different, so you will need to adjust the sensitivity switch when you test another vehicle

until the red and green LEDs flash simultaneously.

2.2.3.

It is possible that a misfire may not develop whilst the engine is at idle, so it may be necessary to test the COP with raised engine revs.

2.2.4.

Continue testing each COP and compare the results.

2.3.

Test results.

2.3.1.

A consistent steady flashing red LED light, supported by an audible beeping indicates that the COP is producing the correct amount of

voltage. No response or an inconsistent reponse indicates that the COP is not producing the correct voltage. Possible causes are a fouled

spark plug or an incorrect gap, damaged or corroded connectors and wires, or a faulty coil.

2.3.2.

A consistent steady flashing green light indicates that the duration of the arc is correct. No response or an inconsistent response

indicates that the duration of the arc is not correct. Possible causes are shorted windings inside the coil, resistance or bad connections, or

a faulty coil.

2.3.3.

Refer to the vehicle manufacturer’s service instructions or proprietary manual to establish the current procedures for repairing or replacing

COP’s.

2.4.

Turning the tester off.

2.4.1.

Turn off the tester by turning the rotary switch until it clicks. The tester will also automatically turn off after approximately 2 minutes of

non-use. Before shutting off, both LED’s flash and a descending beeping sound is emitted.
