2.4 Power Sources
Your diagnostic tool can receive power from any of the following sources:
• Internal Battery Pack
• AC Power Supply
• Vehicle Power
2.4.1 Internal Battery Pack
The diagnostic tool can be powered from the internal rechargeable battery pack. A fully charged
battery provides sufficient power for about 3 hours of continuous operation.
Battery charging occurs when the diagnostic tool is connected to the AC Power Supply and to a
live AC power source.
8
Introduction
Power Sources
The Battery Status Indicator LED (located next to the AC power supply jack) indicates battery
status (Figure 2-3).
• Green - indicates battery is fully charged
• Red - indicates battery is charging
• Amber - indicates a battery issue. This is usually caused by excessive battery temperature
(above 104°F/40°C), which disables charging. Allow the diagnostic tool to cool down be
continuing operation.
2.4.2 AC Power Supply
The diagnostic tool can be powered from a standard AC outlet using the AC power supply. The
connector on the end of the output cable of the AC power supply attaches to the AC power supply
input jack on top of the diagnostic tool. Use only the AC power supply provided.
IMPORTANT:
Never connect the AC power supply to the diagnostic tool when the diagnostic tool is
communicating with a vehicle.
2.4.3 Vehicle Power
All OBD-II/EOBD vehicles have vehicle battery power (B+) available on the DLC. The diagnostic
tool is powered through the Data Cable when connected to the vehicle DLC. A green LED
indicator on the DLC end of the data cable, illuminates when power is being supplied to the cable.
If the LED fails to illuminate, check that the data cable is properly connected and then check the
DLC power circuit. See Data Cable Connection‚ on page 17 for additional data cable information.
An optional power cable is required when testing non-OBD-II/EOBD models that do not have
vehicle battery power (B+) available on the DLC. Contact your sales representative for availability.
IMPORTANT:
Never connect the optional power cable to the AC power supply to the diagnostic tool when the
diagnostic tool is communicating with a vehicle.

OBD-II/EOBD
This chapter describes the basic operation of the OBD-II/EOBD function.
The OBD-II/EOBD icon is located on the Home screen.
The OBD-II/EOBD function allows you to access “generic” OBD-II/EOBD data.
Generic OBD-II/EOBD data is data limited to emission related diagnostics such as:
• Checking for emissions-related diagnostic trouble codes (DTCs)
• Checking the cause of an illuminated malfunction indicator lamp (MIL)
• Checking monitor status prior to emissions certification testing
To access other available electronic control module (ECM) data for vehicle specific systems,
parameters or enhanced diagnostics use the Scanner function, see Scanner on page 19.
i
NOTE:
The OBD-II/EOBD function can also be used to access “generic” OBD-II/EOBD data for
OBD-II/EOBD compliant vehicles that are not included in the Scanner function databases.
6.1 Basic Operations
6.1.1 Screen Layout and Toolbar Controls
Screen layout and toolbar controls are similar to the Scanner function, see Scanner Control Icons‚
on page 20.
6.1.2 Connecting the Data Cable
Connection of the data cable to the diagnostic tool and vehicle DLC is required for OBD-II/EOBD
testing, see Data Cable Connection‚ on page 17.
6.1.3 Saving and Reviewing Data Files
Save and Pause control icon operation and data review procedures are the same as used for the
Scanner function, see Saving and Reviewing Scanner / OBD-II/EOBD Data Files‚ on page 34.
6.2 OBD-II/EOBD Menu
The following options are available from the OBD-II/EOBD menu:
• OBD Health Check
• OBD Direct
54
OBD-II/EOBD
OBD-II/EOBD Menu
6.2.1 OBD Health Check
The OBD-II Health Check offers a way to quickly check for and clear emissions-related diagnostic
trouble codes (DTCs), and to check readiness monitors for emissions testing. Selecting opens a
connection message. Select Continue or press the Y/a button to open a submenu of test options
(Figure 6-1).
Figure 6-1 OBD Health Check menu
Global OBD II Code Check
Global OBDII Code Check displays stored emission related generic DTCs reported by the ECM.
Selecting opens a submenu with two choices: Codes and Pending Codes. Either option opens a
code list (Figure 6-2).
The DTC results screen is similar to the same screen used in the Scanner function, as both display
the SureTrack results message below the toolbar. However, SureTrack is not accessible and no
information is displayed in OBD-II/EOBD mode. SureTrack is only accessible in the Scanner
function where the vehicle has been identified.
Figure 6-2 DTC Results Screen
55
OBD-II/EOBD
OBD-II/EOBD Menu
Codes
The Codes option displays a list of current emission related DTCs.
OBD-II/EOBD Codes have a priority according to their emission severity. The priority of the code
determines the illumination of the MIL and the code erase procedure. Vehicle manufacturers have
implemented the ranking differently, so there are differences between makes.
Pending Codes
The purpose of this service is to enable the diagnostic tool to obtain “pending” or maturing
diagnostic trouble codes. These are codes whose setting conditions were met during the last drive
cycle, but need to be met on two or more consecutive drive cycles before the DTC actually sets.
i
NOTE:
Save valuable time by using this service to verify test results after a single drive cycle following a
vehicle repair and code clearing procedure.
• If a test failed during the drive cycle, the DTC associated with that test is reported. If the
pending fault does not occur again within 40 to 80 warm-up cycles, the fault is automatically
cleared from memory.
• Test results reported by this service do not necessarily indicate a faulty component or system.
If test results indicate another failure after additional driving, then a DTC is set to indicate a
faulty component or system, and the MIL is illuminated.
Refer to the Global OBD Vehicle Communication Software Manual for additional information.
Global OBD II Clear Codes
This option is used to clear all emission related diagnostic data, such as DTCs, freeze frame data,
and test results, from the memory of the selected ECM. Although OBD-II/EOBD displays generic
OBD-II/EOBD data only, clearing codes erases all of the stored data, including any enhanced
codes and freeze frame information.
A confirmation screen displays when the clear codes option is selected to prevent accidental loss
of data. Select to continue from the confirmation screen. Refer to the Global OBD Vehicle
Communication Software Manual for additional information.
Readiness Monitors
This test checks the status of the readiness monitoring system. An OBD-II /EOBD control system
runs continuous and periodic tests to check the status of emission-related subsystems to gauge
the integrity of the electronic operations. Two options are available for Readiness Monitors:
• Monitors Complete Since DTC Cleared—displays the status of all monitors that have run
since the last time ECM memory was erased.
• Monitors Complete This Cycle—displays the status of the monitors that ran during the
current drive cycle only.

Communication protocol is a standardized way of transferring data between an ECM and a
diagnostic tool. Global OBD may use the following communication protocols:
•
•
•
•
•
•
•
•
ISO 15765-4 (CAN)
ISO 27145 (WWHOBD CAN)
ISO J1939 (CAN)

Chapter 8
The Scope Multimeter function allows you to perform multiple types of circuit and component
measurement tests. This chapter includes general operation procedures, instructions for saving
and reviewing test data, optional settings, and general reference information.
8.1 Overview
The Scope Multimeter test functions are:
• Digital Multimeter (DMM)
• Graphing Multimeter (GMM)
• Lab Scope
8.1.1 Digital Multimeter (DMM)
The digital multimeter gives you the ability to quickly make precise common electrical
measurements (e.g. DC and AC voltage, resistance and amperage) on circuits and components
to verify operation. The meter displays measurements in a digital numerical format, and is typically
used for measuring signals that are not rapidly changing.
The DMM is ideal for performing basic tests on most standard automotive circuits, and displays
the results in a large easy to see format.
To use the DMM, select the Scope Multimeter icon from the home screen then select Digital
Multimeter from the menu. See Tests and Capabilities (Quick Reference)‚ on page 79 for a list of
available testing functions.

Scope Multimeter
Overview
8.1.2 Graphing Multimeter (GMM)
Unlike the DMM, the graphing multimeter provides two channels for testing and plots a visual
graphing line of the signal instead of displaying digital values. The GMM displays a signal’s
measurements over time on a two-dimensional grid. This plotted graph is basically a graphical
history (histogram) of the signal’s measurements over time.
The GMM uses a higher sample rate (than a DMM) to calculate signal measurements. This
characteristic along with the visual graph, make the GMM ideal for finding intermittent dropouts or
glitches that may not be obvious when viewing a digital value. A key advantage of the GMM is
being able to capture a signal over a long time interval and then review it’s graphical history, to
visually see if and when dropouts have occurred.
In addition, the GMM uses a combination of filter and peak detect modes to provide a good
balance between detecting fast glitches and preventing unwanted noise from displaying.
Unlike the lab scope, the sweep scales used with typical GMM tests are of longer time intervals,
and may range from seconds to minutes, compared to the lab scope sweep scales that use
relatively short time intervals (e.g. milli and micro seconds). This allows you to monitor a signal
over a longer period of time when looking for erratic glitches or dropouts.
To use the GMM, select the Scope Multimeter icon from the home screen then select Graphing
Multimeter from the menu. See Tests and Capabilities (Quick Reference)‚ on page 79 for a list of
available testing functions.

Scope Multimeter
Overview
8.1.3 Lab Scope
Similar to the GMM, the lab scope (oscilloscope) plots a visual image line of a signal’s
measurements over time on a two-dimensional grid. The visual line that is displayed is commonly
called a trace, and the graphical form created by a signal is called a waveform.
Unlike the DMM, the lab scope allows you to visually see a signals waveform, which in turn allows
you to see the strength and shape of the signal, as well as any noise that may be occurring on the
circuit. The lab scope also samples signals at a high rate, which allows you to see a higher level
of detail in short samples of the signal, especially in signals that change rapidly. In addition, the lab
scope also provides more control over the acquisition of the signal and in how it is displayed,
through the use of triggers and channel controls. All of these features allow you to analyze signals
in great detail when performing diagnostics.
To use the lab scope, select the Scope Multimeter icon from the home screen then select Lab
Scope from the menu. See Tests and Capabilities (Quick Reference)‚ on page 79 for a list of
available testing functions.

Peak Detect
Peak Detect Off
When peak detect is off, the scope samples at a high rate but saves just enough sample points to
the data buffer memory to plot a waveform across the screen. No preference is given to any point
during the selection process.
i
NOTES:
— Turning peak detect “off” is suitable for basic measurements, and viewing waveforms
(e.g. oxygen (O2) or Cam sensor) when capturing fast events is not necessary.
— The longer the time sweep, the greater the chance a glitch could be missed because it
occurred in between the sample points saved to the data buffer memory. To increase the chance
of capturing a glitch with peak detect “off”, a shorter time sweep should be selected.
— Turing peak detect “off” avoids the need for an external filter to decrease the display of
unwanted noise, which can make diagnosis more difficult.
Example: With a time sweep of 10 seconds on a screen 100 points wide, the effective sample rate
would be 10 times a second. Decreasing the time sweep to 1 second, increases the effective
sample rate to 100 times a second. At this time setting, a fast occurring event is more likely to be
captured due to the increased rate. This is the standard mode of operation for many scopes.
96
Scope Multimeter
Operation and Controls
Peak Detect On
When peak detect is “on”, all sample points are evaluated. The points stored to the data buffer
memory are intelligently selected to capture fast events that might be missed at slower effective
sample rates. Peak Detect captures fast events, spikes and glitches for signals going in both
positive and negative directions.
i
NOTES:
— Turn peak detect "on" when capturing fast events (e.g. ignition firing voltage, glitches, and
intermittent events).
— Turning peak detect “on” may capture unwanted noise, therefore, using peak detect may not
be suitable for some tests (e.g. oxygen (O2) sensor), as the waveform may be more difficult to
evaluate due to the additional noise that may be displayed.
— Peak Detect decreases the possibility of waveform aliasing.
To turn peak detect on and off, select the Peak Detect icon.

Scope Multimeter
Operation and Controls
Filter
Using the filter feature can minimize or smooth out signal spikes and fast variations, depending on
which function is its used with.
Filter - Lab Scope
Using the filter with the lab scope, smooths out fast spikes, which helps to provide a good balance
between noise suppression and signal integrity.
Using the filter is useful when working with scales of 5 volts and below, as the lower the voltage
scale, the more likely noise can occur.
Example: Using the filter is helpful when testing components such as, an O2 sensor (1or 2
volt scale), or when performing a throttle position (TP) sensor sweep test (5 volt scale).
In addition, the filter is also helpful for low amp probe tests, as a low voltage scale is used to
measure the output of the probe (due to the conversion factors of the probe).
Example: For a probe with a conversion factor of 100 mV/A connected to a 2 amp load, the
scope uses a 200 mV scale to measure the output of the probe. The scope converts the
measured output to 2 amps for display on the screen.
Filter - GMM
Using the filter with the GMM, the filter minimizes noise by ignoring or smoothing out fast signal
spikes.
• For a direct measurement test, such as volts, amps, or pressure, the filter minimizes the
display of very fast spikes by averaging the sampled data when filter is active.
• For a calculated measurement test, such as frequency, pulse width, dwell, or duty cycle,
extremely fast spikes (20 µS and faster) from sources like the ignition system are ignored
when filter is active.
To turn the filter on and off, select the Filter icon.
Filter Icons
On (Interference is suppressed)
Off (Interference is not suppressed)
Invert
The Invert feature is used to switch signal polarity, so the trace appears upside down (inverted) on
the screen. This is typically used when measuring amperage using the low amp probe, or highvoltage signals like, secondary ignition.
Example: A signal that normally rises from 0 to +5 volts, if inverted would show falling
from 0 to –5 volts.
To turn inversion on/off, select the Invert icon.
Invert Icons
On (Polarity is inverted)
Off (Polarity is not inverted)
98
Scope Multimeter
Operation and Controls
Coupling AC
Coupling AC subtracts the average value of a signal so that small variations can be displayed in
the waveform. This is accomplished by blocking the direct current (DC) portions of a signal in
order to amplify (show) the alternating current (AC) portions of the signal, without driving the trace
off of the screen.
Using coupling AC can be helpful when testing and diagnosing alternator ripple or fuel pump
amperage, by allowing you to see any abnormal small variations or events.
To turn coupling AC on and off, select the Coupling AC icon.
Coupling AC Icons
On (DC signal portion blocked)
Off (DC signal portion not blocked)
Trigger
i
NOTE:
The Trigger feature is only available in the lab scope function.
A trigger can be used to stabilize a changing or erratic signal (a signal that may flicker or drift as it
refreshes), so that it is easier to view or diagnose. This stabilization effect is accomplished by
basically displaying the same part of the trace repeatedly from the same starting point, thus the
flicker or drift is minimized which makes the trace appear more consistent or static.
A trigger is basically a “specific point” on the display, at which a trace will start to display (start the
sweep) if it crosses that point.
The trigger feature allows you to set the conditions of that “specific point” also called a “trigger
point”. When the trigger conditions are set, and a trace “meets” those conditions (crosses the
trigger point), the trace will start.
Trigger conditions:
• Vertical scale position (amplitude)
• Sweep position - the horizontal scale position, or position in time
• Slope direction - the direction the trace must be moving (up/rising or positive) or (down/
falling or negative) when crossing the trigger point.
i
NOTES:
Triggers can be set on any channel, however only one trigger can be activated (used) at a time.
If a trigger is set outside the range of the scales, a yellow marker (e.g. arrow with plus symbol) will
be displayed (Figure 8-22) indicating the trigger is out of range and a confirmation screen will
display.
When a trigger is set on a channel, and more than one channel is active (displayed), trigger
conditions must be met for that channel in order to display all the other channels.

3. Proceed to “To set trigger position” next to complete the trigger set up.
z
To set trigger position:
Trigger position (also called trigger level) can be adjusted in two ways:
– Dragging the trigger marker (Figure 8-21) on the touch screen - rough adjustment
– Using the trigger position control panel (Figure 8-21) - fine adjustment
The trigger marker is indicated by a plus symbol (+) on the display (Figure 8-22). The trigger
marker represents the trigger point and is displayed on the screen when the trigger is turned
on.
To roughly position the trigger marker, select and drag it into position using the touch screen.
4. To more accurately position the trigger marker, select the Trigger Position Control icon
(Figure 8-22).
The trigger position control panel opens.
5. Use the directional controls provided, or the thumbpad directional controls to move the trigger
marker into position (Figure 8-21). Sweep and vertical scale values are provided in the trigger
position control panel, which gives you the precise position of the trigger marker.

Trigger Auto/Manual Mode (Optional Setting)
i
NOTE:
The Auto and Manual Trigger modes allow you to set the criteria used to display signals on the
screen. To change the trigger mode, the trigger must be set on one of the channels.
In both Auto and Manual Trigger mode the screen is updated when the signal crosses the trigger
point in the selected direction (rising or falling), however:
• Auto Trigger—(default mode)
– when Auto Trigger is on, even if the signal does not cross the trigger point, the screen
automatically updates after a short period (allowing you to see the waveform). When this
occurs, the message "Waiting for the trigger" (Figure 8-22) is displayed on the screen.
The trigger point can then be set to optimize viewing.
• Manual Trigger
– when Manual Trigger is on, if the signal does not cross the trigger point the screen will not
update. This allows you to capture intermittent events, as the screen only updates when
the signal meets your trigger selection.
i
z
NOTE:
When using Manual Trigger, it may be easier to initially set the trigger point using Auto Trigger, as
the screen will update regardless if the signal crosses the trigger point. Once the trigger point is
set, then switch to Manual Trigger mode.
Selecting Trigger Auto/Manual Mode:
1. From the Control Panel (on the test meter screen), turn the trigger on for the desired channel.
2. Select the Settings icon from the toolbar.
3. Select Settings > Configure Scope / Meter > Trigger Mode from the menu selections.
4. Select either Auto Trigger or Manual Trigger.
5. Select Back or press the N/X button to navigate back to the test meter screen.
Threshold
i
NOTE:
The Threshold function is only available in the Graphing Meter function for specific tests. This
function may also be referred to as Auto Threshold Select (ATS).
The Threshold function can be used, to display and obtain a more accurate measurement when
measuring signals (e.g. Frequency, Duty Cycle, MC Dwell and Pulse Width) that may be difficult
to display or have noise or other undesirable variations in the signal. When selected, the
Threshold function automatically sets a trigger and determines a threshold level in the middle of
the signal range (calculated from the Min and Max measurements) to be used as a reference point
to calculate the measurement. The falling edge (slope) of the signal is used in determining the
threshold level.
102
Scope Multimeter
Operation and Controls
To activate the Threshold function, select the Threshold icon, then select Continue from the
confirmation screen (Figure 8-23). Once selected, the Threshold function remains active until the
test is exited.
Figure 8-23 Auto Threshold Confirmation Screen
If after enabling the Threshold function, if the signal is still not displayed, reduce the vertical scale
setting. Sometimes a low frequency signal may not display if the vertical scale is set too high. If the
signal still seems incorrect use the lab scope to verify the signal integrity and signal spacing. Slow
or unequal spacing will display as a band or ragged signal, depending on the sweep setting.
Refresh
Selecting the Refresh icon (Figure 8-24) clears the active trace(s) displayed and restarts the
signal tracking from zero. It also clears the minimum, maximum and live measurements displayed
for both channels.
Use the Refresh feature to:
• Track the variation in a component or circuit under a certain condition. If the condition
changes, Refresh lets you start tracking again to see the change.
• Verify that a connection problem you found by looking for a dropout or spike in min/max values
has been fixed.

Cursors
i
NOTE:
The Cursors feature is only available in the lab scope and Graphing Meter functions.
Two vertical cursors are provided that allow you to make precise signal measurements, when
determining signal characteristics such as, amplitude at specific points, and cycle time (duration)
or frequency.
Using cursors can also be helpful when performing certain diagnostic tests, such as:
•
•
•
•
O2 sensor rich/lean switch time
fuel injector pulse width frequency
secondary ignition spark duration
crankshaft position sensor frequency
Measurements can quickly be taken between the two cursors, when measuring a single cycle or
across multiple cycles by positioning the cursors at the start and end of the cycle or multiple
cycles.
The cursor measurements panel is displayed when using the cursors, providing you digital values
of the cursor measurements. See Cursor Measurements Panel‚ on page 106 for additional
information on the values displayed in the cursor measurements panel.

Cursor 2 - cursor position in time at cursor 2
Delta - difference in time between cursor 1 and 2
Frequency - the frequency value (Hz) of the signal for the time period between cursor 1
and 2
NOTE:
Frequency is the number of times a signal repeats itself per second and is measured in hertz (Hz).
The frequency value displayed, is the inverse of the Delta value, and can also be calculated as 1
divided by Delta. The frequency value (Hz) shown is automatically calculated by the scope.
Example 1: Delta = 20.46ms, to get frequency divide 1 by .02046 (1/.02046 = 48.87Hz)
Example 2: Delta = 2.53ms, to get frequency divide 1 by .00253 (1/.00253 = 395.27Hz)
Use applicable decimal point placement during division as the Delta value changes.

NOTE:
This setting ONLY changes the vertical scale, the sweep (horizontal) scale is NOT changed.
NOTE:
When adjusting the vertical scale setting, it is important to remember that the vertical scale is
divided into 10 major divisions, and all scale adjustments reflect this factor of 10. The division set
of 10 cannot be changed, divisions cannot be added or removed.
Trace Full Scale - changes the dropdown vertical scale menu selections to full scale mode, which
represents the selected unit of measurement over the entire (full) scale.
Example (Figure 8-29): Selecting 10V, changes the vertical scale to a 10V volt scale. The vertical
scale is “always” divided by 10, therefore each division is incremented by 1V.

Saving and Reviewing Scope / Multimeter Data Files
8.7 Saving and Reviewing Scope / Multimeter Data Files
The following section describes the procedures used to save and review Scope/Multimeter and
Guided Component Tests data files.
8.7.1 Data Buffer
The graphing multimeter and lab scope functions have the capability to save, store and playback,
data (test signals) utilizing internal storage memory and buffer memory.
When a test function (e.g. Lab Scope > DC Volts) is selected and displays onscreen, a data buffer
automatically starts to store data in buffer memory. The data buffer runs continuously (storing
data) until the Stop icon is selected.
i
NOTE:
The data buffer starts and runs continuously with or without an active input test signal, when a test
function is selected.
The Data Buffer Indicator can be used to visually see the amount of stored buffer data. This
graphical indicator contains a slider within a bar graph. The bar graph shows how much stored
data is in the memory buffer. The slider indicates the position of the current screen in relation to
the entire memory buffer contents.
The Data Buffer Position Counter displays a numerical value, indicating the position of the current
displayed frame of data within buffer memory.
1— Data Buffer Indicator Slider
2— Data Buffer Indicator Bar Graph
3— Data Buffer Position Counter
Figure 8-33
Buffer memory is limited to a predetermined “total” size. When buffer memory reaches it’s full
capacity, the data buffer will continue to store new data, however earlier stored data will be
removed to allow room for the new data being stored.
The most recent data is always available for review when the scope is stopped, and can be
reviewed using the toolbar controls.
113
Scope Multimeter
Saving and Reviewing Scope / Multimeter Data Files
8.7.2 Saving Files
Selecting the Save icon writes the data stored in buffer memory to a file. Saving data files is useful
when trying to isolate an intermittent problem or to verify a repair during a road test. The saved file
can be played back (similar to a movie clip) by selecting Previous Vehicles and Data > View
Saved Data. See View Saved Data‚ on page 128 for additional information.
i
NOTE:
The Save icon performs the same function as “Save Movie” function choice for the programmable
Shortcut button, see Configure Shortcut Button‚ on page 131 for details.
The saved file can also be downloaded to a personal computer (PC) using the Mini USB jack.
Once connected to the PC, the files can be printed, transferred, and copied using ShopStream
Connect. ShopStream Connect is a companion application that interfaces the diagnostic tool with
a PC. ShopStream Connect is available at no cost, and can be downloaded online. See the
ShopStream Connect website information at the front of this manual for additional information.
The toolbar control icons are described in Scope Multimeter Control Icons‚ on page 86 and
Common Toolbar Control Icons‚ on page 15.

To save files:
• Select the Save icon from the toolbar.
A save dialog box displays while files are being saved. The file is saved when the message
box disappears.

8.7.3 Stopping and Reviewing Data Files
During normal scope multimeter operation, data is continuously being store stored in buffer
memory as it is displayed onscreen. The Stop feature, allows you to temporarily stop the
waveform (signal) to review it in detail.
i
z
NOTE:
Glitches may cause drivability problems and may not turn on the MIL or set DTCs. As a general
guide when looking for a suspected signal glitch, always try to verify the problem by duplicating the
conditions while capturing data. Utilize the GMM to monitor the signal over longer time periods
and review the histogram for possible faults.
To stop and review data files
Playback control icons are described in Scope Multimeter Control Icons‚ on page 86 and Common
Toolbar Control Icons‚ on page 15.
1. While viewing a waveform (capturing data), select the Stop icon.
The playback control icons are displayed.
2. Select the desired playback control icon to step forward or backward through the data.
You can also use the data buffer indicator slider to quickly scroll through the captured data in
buffer memory (Figure 8-35).

The Shortcut button can be set to perform the Pause/Play function. See Configure Shortcut
Button‚ on page 131 for additional information.
8.7.4 Saving Screens
The Shortcut button can be programmed to save a snapshot (screen shot) of a visible screen as
a bitmap file, see Configure Shortcut Button‚ on page 131 for details The saved file can be viewed
by selecting Previous Vehicles and Data > View Saved Data, see View Saved Data‚ on
page 128 for additional information.
8.7.5 Using the Zoom Function
The zoom function allows you to change the magnification level of the signal sweep during data
review. Changing magnification levels allows you to compress or expand multiple screens of data
to quickly find glitches, or signal losses.
Example: While monitoring a MAF (Mass Air Flow Sensor) signal, the waveform displays
normally. As the signal is being monitored, an erratic “condition” suddenly develops, then goes
away, but may have not been observed on the screen. Stopping the data capture (when such
an event occurs) allows you to analyze the waveform using a higher zoom level (wider view)
to look for a glitch in the signal.
During data capture, the default magnification level is 1x. The zoom function is not available until
data capture is stopped by pressing the Stop icon (Figure 8-37).

NOTE:
Zoom playback controls are identical to the standard playback controls used when reviewing data
files, with the following exception:
Skip Forward / Skip Back control icons - (press once) moves multiple steps relative to set
magnification level (e.g. 2X setting, moves 2 steps; 16X setting, moves 16 steps)
Additional information on playback control icons are described in Scope Multimeter Control Icons‚
on page 86 and Common Toolbar Control Icons‚ on page 15.
When the Zoom icon is selected the display defaults to the "Max" magnification level and a
dropdown scroll menu displays. The dropdown menu allows you to select the display
magnification level from a range of 1X to 256X. The "Max" (maximum) option displays all data
captured on one screen (Figure 8-37).

4— Zoom Cursor
Figure 8-37 “Max" Magnification Level - displays all captured data
When zoom levels of 2X and higher are selected, a Zoom cursor (vertical dashed line)
(Figure 8-37) displays onscreen. The cursor is used to quickly mark and navigate to points of
interest or glitch in a captured waveform.
The Zoom cursor can be used to mark the approximate position of a glitch and can be manually
dragged onscreen to the desired position. The new cursor position will be centered on the screen
when a lower magnification level is selected. Figure 8-38 shows examples at 32X and 64X with
the Zoom cursor positioned in the area of a signal drop glitch.
i
NOTE:
To quickly identify a glitch in a pattern, it may be easier to initially view the waveform at a higher
magnification level (e.g. 256X or "Max") to display the entire captured waveform, then lower the
zoom level to 8X or 2X to review in detail.

8.8.1 Basic Setup Tips (unknown signal type)
When conducting automotive diagnostics, situations may arise when you need to capture and
analyze a signal that you are not familiar with, or know what the intended waveform pattern should
look like, or even how to set the scope to acquire the signal.
The following tips are intended to provide guidance, at the most basic level to assist you in your
lab scope diagnostics.
Testing information and/or procedures for testing certain components may be available in the
Guided Component Test function, see Guided Component Tests‚ on page 64 for additional
information. If you have already narrowed down the system and/or component to test, ID the
vehicle within the Guided Component Test function, and check the available tests first, as this may
save you some time.
If the Guided Component Test function, does not have the test you are looking for, you need to
determine are few thing about what you are testing to get the scope / meter set up to capture a
signal or make a measurement.
i
NOTE:
Testing information and known good waveform libraries may also be available from other sources
(e.g. SureTrack, ShopKey Pro or other online sources). Obtaining correct testing reference
information can be a key advantage in making sound repair decisions.
Listed below are a few basic questions to help narrow down the testing direction to follow.
• Are you looking to make or test a simple voltage or current level or maybe check resistance or
continuity? Then you may want to use the DMM.
• Are you looking to check a circuit/component for an erratic dropout or make a frequency test?
You may want to use the GMM.
• Do you need to see signal details (level, shape, frequency etc.)? The lab scope may be the
best choice.
• Are you testing a DC or AC signal?
• What is the operating range of the circuit?
• Do you know what type or shape the intended waveform should be?
After answering the questions above (at a minimum), you need to determine which Scope /
Multimeter test function you are going to use (e.g. Lab Scope, DMM or GMM). See Tests and
Capabilities (Quick Reference)‚ on page 79.
Once your test function is selected, you can now connect the test leads and select the applicable
probe and scales:
Probe (test) type, see Probe (Probe type “test” selection)‚ on page 94
Vertical scale, see Scale (Vertical scale adjustment)‚ on page 91
Sweep scale, see Sweep (Horizontal or Time scale adjustment)‚ on page 93
Connect the test leads or probe, to the applicable test point(s). Always use the correct lead or
probe designed for the test and ensure the signal and ground connections are clean and secure.
For the initial setup, you may wish to turn other channel settings off (e.g. Peak, Filter, Invert, AC
Coupling, Threshold etc.), as these may affect the signal display. See Channel Settings‚ on
page 95.
119
Scope Multimeter
General Reference
As a default setting, trigger is normally off. The scope/meter uses internal circuitry to display a
signal if present. However, in certain circumstances additional channel adjustments may be
required, or the trigger mode may have to be turned on, for a signal that is present but is not
displayed. You may also need to readjust the vertical scale if set to low, in order to bring the signal
into the viewable display area.
At this point you should have a visible signal on the screen. An ideal signal should be displayed
within the area of the display.
• If the signal goes beyond the top and bottom of the display, try and readjust the vertical scale
to a higher setting, to bring the signal into the viewable display area.
Use the zero baseline controls or move the zero baseline marker onscreen to move the zero
baseline of the signal vertically on the screen to the desired position. See Trace (Zero Baseline
position adjustment)‚ on page 96.
• If the signal cycles are compressed (close to each other), try and readjust the sweep scale
(horizontal scale) to a lower setting to display less cycles.
Once you have a usable signal displayed, if needed use the trigger function to stabilize a changing
or erratic signal (a signal that may flicker or drift), so that it is easier to view. Try and set the trigger
at the mid-point of the signal, and then adjust as needed from there. See Trigger‚ on page 99.
As all signals are different, and due to other variables, additional adjustments may be needed to
get the signal displayed exactly how you need. Review the channel settings section in this manual
for additional information on using the settings. See Channel Settings‚ on page 95.
At this point you should have a signal displayed that will allow you to see the overall signal
characteristics, and allow you to begin your diagnosis.
Comparing your captured waveforms to known good waveforms, can be a time saver and provide
supporting evidence when trying to determine a fault. See Using Known Good Waveforms‚ on
page 120 for additional information.
8.8.2 Using Known Good Waveforms
In some cases captured waveforms may not provide enough information to determine if a
suspected sensor or circuit is at fault. Comparing the test vehicle waveforms to known good
waveforms, can help to provide supporting evidence when trying to determine a fault.
Known good waveform examples may be available from different sources including the Guided
Component Tests function, information services (e.g. ShopKey Pro) or from other sources.
One of the many resources available within the optional online version of SureTrack is the
comprehensive collection of known good component waveform examples gathered through
actual vehicle tests. Waveform and PID graph screenshot examples are provided by fellow
member technicians and shared with all members in a searchable (vehicle/component specific)
database.
As good practice, capturing waveforms before and after the repair will help you to build your own
library of waveforms for future troubleshooting.

8.8.3 Troubleshooting Signals
When capturing signals, you may occasionally encounter problems with the way the signal initially
displays. Noise, hash, fuzz are some of the terms used to describe, unwanted signals displaying
in or on the signal you are trying to capture, basically making the signal unclear. The following tips
are intended to provide some basic guidance, to help resolve these types of issues if encountered.
• Make sure you have the correct test leads connected to the applicable test point(s) and test
lead jacks on the diagnostic tool.
• Ensure the signal and ground connections are clean and secure, at the test points and
diagnostic tool.
• Ensure the polarity of the test leads connections are correct.
• If using stackable connectors, try to isolate or only connect the leads being used to capture the
signal.
• Make sure the ground lead is providing a direct ground from the circuit to the diagnostic tool
test lead jack.
• Isolate the test leads from other components, leads, or systems that may induce unwanted
noise into the signal being tested (e.g. electric motors, secondary ignition components, relays,
alternators, etc.)
• Use the shortest test leads possible.
• Try different test leads, to verify the issue. Use the recommended snap-on leads or probes
available for the diagnostic tool or equivalent. Shielded test leads are recommended.
• Check the test lead or probes for damage.
• Enable or disable channel controls also to help try and clean the signal:
– Peak Detect—maximizes sampling rate, but may pickup unwanted noise
– Filter—removes signal noise or interference
– Invert—switches signal polarity
– Coupling AC—blocks the DC portion of signal
– Threshold —provides a more accurate measurement on select GMM tests where noise is
present
– Scale (Vertical scale adjustment)—adjusts vertical scale. Using a higher setting may
provide a cleaner signal in some situations.
For signals that do not display or display off the screen, erratic, compressed etc.:
• Use a trigger to help stabilize the signal. Try and set the trigger at the mid-point of the signal,
and then adjust as needed from there. See Trigger‚ on page 99.
• If the signal wraps off the top and bottom of the display, try and readjust the vertical scale to a
higher setting, to bring the signal into the viewable display area. See Scale (Vertical scale
adjustment).
• If the signal cycles are compressed (close to each other), try and readjust the sweep scale
(horizontal scale) to a lower setting to display less cycles. Try a higher setting if the cycles are
spread too far across the screen and seem flat. See Sweep (Horizontal or Time scale
adjustment)‚ on page 93.
• Move the zero baseline marker to move the zero baseline of the signal vertically on the screen
to the desired position. See Trace (Zero Baseline position adjustment)‚ on page 96.
• Check calibration of test leads or probe(s) if applicable. See Test Lead / Probe Calibration‚ on
page 89.
