7. MEASUREMENT PROCEDURES

CAUTION

To avoid personal injuries and damage to the instrument carefully inspect the

spark plug wires, distributor cap, ignition coil , ignition module, and all other

ignition system parts for damage or leaks, and avoid using this instrument in

case any damage or leaks are found. Never touch the capacitive pick-up or

exible probe during a test.  Wear insulating gloves when working around high

voltage, and hot parts, and keep away from moving parts (fan, drive belts, etc)

and hot objects (exhaust manifold and pipes, mufer, catalytic converter, etc.)

7.1 Flexible probe and pick-up setup

Thisinstrumentissuppliedwithaexibleprobe,andtwotypesofpick-upsensors:

• Flexibleprobe:equippedwithaBNCconnectoratoneendandabarrelconnectorat

theother.

• COPpick-up:formeasuringcoilonplugandcoilnearplugignitionsystems.

• SPWpick-up:forallignitionsystemswhichusehighvoltagewires(sparkplugwires)

toconnecttheignitioncoilordistributortothesparkplug.

Fig.10-Pick-upconnectiontoexibleprobe

1- ConnecttheprobetotheinstrumentusingtheirBNCconnectors.

2-InsertandrmlypresstheappropriateCOPorSPWpick-upintothebarrelconnector

oftheprobe.

NOTE: Theinstrumentwillautomaticallydetectandcongurethepick-upconnectedtothe

probe.Usingthewrongpick-upfortheignitionsystemundermeasurementmay

leadtoerroneousreadings,ornoreadingsatall.

7.2 Measuring coil on plug and coil near plug ignition systems

1-Ensuretheinstrumentisturnedoff.

2-InserttheCOPpick-upbarrelconnectorplugintotheexibleprobereceptacle,removing

theSPWpick-upifnecessary.

3- Turn the instrument on and select the appropriate cycle for the engine under

measurement.

4-Selectthedesiredmodeandview.

5- PlacetheCOPpick-uponthetopandcenteroftheignitionmodule(asshowninthe

Fig.11),andobservewhethertheinstrumentisabletodetectanddisplaythedesired

measurement.
