B. Overview
1)
DCN PRO is the world's first scan tool with a 4-channel oscilloscope function . It
can display up to four scope waveforms at a time.
The oscilloscope is not designed for R&D or research in labs , but for analysis of
electric and electronic signals in automo tive circuits .
2)
The Oscilloscope measures and displays DC voltage and up to 100kHz of an AC
signal.
a.
Time division : 25/Ls - 20s

Calibration
If the voltage values are not equal to zero when the pro bes are not aUached to
any voltage source, the voltage output may not be correct. If this occurs,
calibration is necessary .
For proper calibration, connect the probes of each channel to the ground port
of the 4-channel adaptor and then press the [O] key.
3. Duty Cycle
A. Duty Cyc1e
The Duty Cycle function can be used for the rectangular type signals.
In example, Duty Cycle is especially useful for checking the performance of
Idle Speed Control motors, especially for the duty-control type vehicles as
opposed to frequency or voltage control type. The engine load increases when
accessories such as air conditioner, power steering or other power consuming
items are running. The ISC motor therefore increases its active time to increase
the engine RPM for compensation . The Duty Cycle module of DCN PRO
enables the user to check this performance of ISC motor.
B. The waveform ofISC motor

1. Introduction
A. What is an Ignition Pattem?
An Ignition Waveform is a graphical representation of voltage fluctuations in a
recurring procedure - the high voltage from the secondary ignition coil which is
created when the electric power in the primary coil that was fuliy charged by power
TR collapses when the power TR is turned off. This produces a spark over the
gap of the spark plug in the cylinder, which is used for combustion of the air-fuel
mixture.
DCN PRO can analyze both Primary and Secondary Ignition Waveforms.
B. Purpose ofIgnition Pattem Analysis
The Ignition Waveform Analysis function of the DCN PRO is to provide an
accurate visual representation of ignition waveforms to enable the user to analyze
the possible causes of problems within the ignition system.
By designating X(horizontal) axis for time and Y(vertical) axis for voltage, the
change of voltage in relation to elapsed time during the spark-ignition sequence
can be graphed as a waveform. Waveforms have typical characteristics of height
and duration that can be influenced by various factors.
Since each of these factors brings about a noticeable change in the ignition
waveform, the cause of a malfunction can be traced by analyzing the transformed
waveform in reverse.

DeN PRO USER'S MANUAL
You will find the inscription 'This side to the spark plug' on one side of the
clamp. Connect the clamp to the spark plug cable of cylinder #1 so that the
inscribed side faces the #1 cylinder spark plug. The spark plug that is nearest
to the generator is usually the #1 plug.
When the clamp is connected properly and the clamp picks up the trigger well,
then DCN PRO will indicate it by flickering the ground mark ( 'Y ) on screen .
When the clamp is not connected properly, a waveform may still be displayed
but without or incorrect cylinder numbers. In case the high tension cable is not
available or the #1 cylinder doesn't ignite, the clamp should be connected to the
spark plug cable of the other cylinder. The ignition order will then be
determined.
DCN PRO recognizes the cylinder to which the trigger pickup clamp is
connected to be Cylinder #1 . The ignition order of 4-cylinder engines is usually
1-3-4-2. For example, if the clamp is connected to cylinder #3, the ignition
waveform will be displayed in a row as 3-4-2-1 while DCN still displays the
cylinder indicator as 1-3-4-2. Accordingly, when connected to cylinder #2, the

incorrect line.
DANGER
CAUTIONI
Be sure NOT TO attach the probe needle to any high tension cables
attached to the ignition plugs or the center cord that connects the distributor

extremely dangerous to attach the probe needle to such high voltage lines.

Since it is very easy to find the primary lines for conventional cars with

selected as the trigger. The secondary signal is not stable enough since it
fluctuates in relation to engine RPM and engine load . In this case, DCN

It is easy and simple to use the secondary signal as trigger - just connect
the probe without needle to a high tension cord. That is all.
However, since the secondary signal is easily affected by engine RPM
and engine load, the resulting waveform may be incorrect and unstable.
Therefore, it is always recommended to use the Primary signal as a trigger.
Despite all the reasons for use of primary ignition signal, sometimes it is
necessary to use the secondary trigger signal when the primary lines cannot
be found. Sometimes the lines of some DLI cars are hidden under metal
shields and plates or may be too short for proper attachment of the probe.

As shown in the illustration, DCN PRO displays two waveforms . This is
because an ignition Coil of this type discharges both positive and negative
electricity simultaneously to two spark plugs.
For 4-cylinder engines, there are two ignition coils and each coil is connected
to two spark plugs. When one of the coils discharges positive electricity for
example to cylinder #1, it also discharges negative electricity to cylinder #4
simultaneously. When the other coil discharges positive electricity to cylinder #3,
it also discharges negative electricity to cylinder #2 simultaneously.
Therefore, there will be positive discharges in cylinder #1 and #4, and negative
discharges in cylinder #3 and #2 at the same time. Will this cause cylinder #1
and #4 to fire together? No. When one cylinder is in combustion stroke, the
other will be either in the exhaust, intake or compression stroke. Since the
mixture in the other cylinders is not dense enough to properly combust, it burns
but does not fully combust.
From the two cylinders that ignite together, the waveform of the valid electricity
discharge that creates combustion is called 'True Waveform', and the other that
ignites but does not fully combust is called 'Waste Waveform'.
The density of mixtures in the cylinders that are in the strokes other than
combustion stroke are below combustible level. The higher the resistance level,
the higher the voltage is required to bridge the ignition gap . This means that the
peak voltage of the TRUE waveform is higher than that of the WASTE waveform.
Between the two waveforms , TRUE waveform can be distinguished from the
WASTE form in this manner. In ILL. 43, the second waveform is TRUE .
