5. MEASURING MODESThere are four different ignition systemparameters that can be selected formeasurement,dependingontheengine’signitionsystem:•EngineRPM.

•Sparkburn(firing)time.

•Sparkplugvoltage.

•Dwellangles(forignitionsystemsequippedwithhighvoltagesparkplugwires).

•Primaryignitioncoilcurrentramptime(forcoilonplugandcoilnearplugignitionsystems).

5.1 Engine RPMMeasuresengineRPM(revolutionsperminute)in2and4strokeengines,andmaybeusedincombinationwithothermeasurementstoevaluateignitionsystem performanceatdifferentenginespeeds.

5.2 Spark burn (firing) timeThe spark burn time, also called “firing time”, is themeasurement of the period fromthemomentasparkisinitiateduptothepointwhenit isextinguished,andisthemostindicativemeasurementofperformanceoftheignitionsystem.Abnormallylongorshortburntimesmayindicatesomeproblemintheignitionmodule,sparkplug,fuelmixture,cylindercompression,etc.

5.3 Spark plug voltageSparkplugvoltagevaluesareusefulforcomparingtheperformanceoftheignitionsystembetweencylinders.Thismaybeusedtodiagnosecommonproblemslikemisfires,brokensparkplugwires,etc.Sparkplugpeakvoltagesmayvarywidely,arelessconsistentandnotalwaysindicativeofaproperlyworkingignitionsystem.Ontheotherhand,observationofthesparkplugvoltagewaveformortrendmayproveusefulindiagnosingignitionandmechanicalproblems.

5.4 Dwell angle (for ignition systems using spark plug wires only)Dwellangleisameasurementoftheangleofrotationofthecrankshaft,betweenthemomentinwhichtheprimaryoftheignitioncoilisenergized(e.g.pointcontactsclosed)andthesparkisgenerated(e.g.pointcontactsopened).Itsmainuseisindeterminingifthereisenoughangle(ortime)toenergizetheprimaryoftheignition,andnotsomuchastocausetheignitioncoiltooverheatandfail.DwellanglesarespecifiedforaparticularengineandRPM,andusuallyadjustedinthemechanicaldistributor/pointassembly.

5.5 Current ramp time (for coil on plug and coil near plug only)Ramp time ismeasured fromwhen theprimary coil current first begins to increase towhenitstopsincreasing.Thecurrentmaystopincreasingbecausethecoilhasreacheditssaturationpoint,oritisinterruptedtogenerateaspark.

Ramp timemeasurementsareuseful fordiagnosingproblems in theprimarycircuitoftheignitionmodule.Abnormallylongramptimesmayindicateexcessiveprimarycircuitresistance,lowinputvoltage,thatthewrongmoduleisinstalled,etc.Shorterthannormalramptimesmayindicateashortedprimarycoil,thatthewrongmoduleisinstalled,etc.

7. MEASUREMENT PROCEDURES

CAUTIONTo avoid personal injuries and damage to the instrument carefully inspect thespark plug wires, distributor cap, ignition coil , ignitionmodule, and all otherignition system parts for damage or leaks, and avoid using this instrument incase any damage or leaks are found. Never touch the capacitive pick-up or flexible probe during a test. Wear insulating gloveswhenworking around highvoltage, and hot parts, and keep away frommoving parts (fan, drive belts, etc)and hot objects (exhaustmanifold and pipes,muffler, catalytic converter, etc.)

7.1 Flexible probe and pick-up setupThisinstrumentissuppliedwithaflexibleprobe,andtwotypesofpick-upsensors:

• Flexibleprobe:equippedwithaBNCconnectoratoneendandabarrelconnectorattheother.

• COPpick-up:formeasuringcoilonplugandcoilnearplugignitionsystems.

• SPWpick-up:forallignitionsystemswhichusehighvoltagewires(sparkplugwires)toconnecttheignitioncoilordistributortothesparkplug.

NOTES

• The position of the pick-up and the particular design of the ignitionmodulemayaffect the signal’s shapeshownwhen thewaveformdisplay is selected. Inorder tocomparewaveformsbetweenseveralcylinders’ignitionmodules,theplacementofthepick-uprelativetotheignitionmoduleshouldbekeptasconsistentaspossibleforallthemeasurements.

•In someengines, the ignitionmodulesare located very close together, and in rareoccasions this could cause the instrument’s pick-up to detect signals fromnearbymodules,leadingtoinconsistentmeasurements.Thiscanusuallybesolvedbychangingtheplacementororientationofthepick-upontheignitionmodule.
