BOSCH MTS 5200 LAB SCOPE
OVERVIEW
21-800-71-TRAIN (1-800-718-7246) OR www.auto-video.com
For this training session we will be discussing the Bosch MTS 5200 Lab Scope. Why is the use of
a lab scope in your diagnostic strategy important? The answer is that a scan tool can only go so
far. The Tech 2 for example is able to retrieve fault codes and provide you with diagnostic
information that will point you in the right direction for your diagnostic process. However, if you
have a code for a faulty TP sensor for example, the scan tool will tell you if the sensor is
responding or whether or not you have voltage to the sensor. The scan tool will not tell you what
the exact source of the problem is.
A lab scope, such as the MTS 5200, will help you to pinpoint the exact cause of the problem and
verify fixes fast. Using the MTS 5200 you will be able to check the wires to the sensor to
determine if the proper amount of voltage is being supplied, and also test for a proper ground
signal. Then you can specifically test the sensor itself for proper usage and accuracy.
esigned for professional automotive technicians, the MTS 5200 is a high speed data acquisition
product. The MTS 5200 utilizes a real-time operating system to run a RISC based computing
environment, giving you lightning fast measurement capabilities. This hand-held state-of-the-art
tester contains a number of diagnostic instruments providing automotive professionals with the
tools required to diagnose sophisticated electrical and mechanical systems on today’s modern
vehicles. The tester supports multiple languages.
The MTS 5200 color touch screen user interface enables you to select from a number of different
test modes such as 4-Channel Oscilloscope, Graphing Multimeter, VOM, Vacuum Waveform, and
Primary/Secondary Ignition. You can configure these functions to allow you to take charge of the
diagnostic process and let you perform circuit testing down to a component level.
WHAT MAKES A GOO LAB SCOPE?
A good lab scope needs to be designed for a technician to be able to use it on a regular basis. If
you have ever purchased a lab scope and it was too complicated to use, you may not use it often
enough to become comfortable using it in your diagnostic process.
The MTS 5200 is designed to be user friendly to the technician. All of the connections on the
MTS 5200 are easy to find and well labeled. Also, the menu and navigation system can be
mastered in a reasonable period of time.
There are other features to look for when buying a lab scope. One of those is the refresh rate. A
good refresh rate for a lab scope is twice the speed of the sensor that you are testing. For most
cases a lab scope that is reading at 1,000,000 samples per second is more than enough to
capture anything under the hood of the vehicle.
This is actually one of the features that you don’t want to get really concerned about. If you have
a lab scope that is incredibly fast, but the screen that you have on the scope is not capable of
showing those points, then it doesn’t do you a lot of good. One of the advantages of the MTS

WHAT MAKES A GOO LAB SCOPE? (CONTINUE )
5200 is that the refresh rate of the screen is 12 times per second, which is double of what the
human eye can actually see.
Another feature that you want to make sure the lab scope has is a multi-channel connection. The
MTS 5200 has four individual color coded channels, and each channel has their own analog to
digital converter. This means that each one of the channels must be able to sample the data
that is coming into it. By having four channels with each having their own analog to digital
converter, you are far less likely to miss any fault events while sampling other data on one of the
other channels.
Another thing to look for in a good lab scope is how good the processor is. Traditionally, most lab
scopes use an 8 bit processor. This means that the processor is going to use 850 dpi to draw the
image on the screen. A better lab scope will use a 12 bit processor which will display the image
at 4090 dpi resolution. The better the resolution, the better you will be able to view images such
as secondary waveforms. The MTS 5200 uses a high end processor to give you the maximum
capability for viewing images.
The MTS 5200 has bonus features that you may not find in most lab scopes such as the ability to
record data & playback, store images and the ability to create a database of known good values
for the vehicles you work on.
The ability to create a database of known good values is one of the best features of the MTS
5200. As you build this database over time, you will have data to compare problem vehicles with
and be able to narrow down the cause of faults faster and more accurately.
HOW TO GET STARTE WITH YOUR LAB SCOPE
One of the best places to get started on with your lab scope is to read the manual that came
with it. The MTS 5200 comes with an extensive 222 page manual that goes into great detail on
the tools functions, how to navigate them and how to use them. Also included are examples of
what the lab scope is capable of and how to apply it to real world situations. Later in the
program we will show you how to download the manual from the manufacturer’s website. Be
sure to read it once you have downloaded it. Also, you will need to have to start learning to use
the lab scope on your own time. This means that you should use training aids like a
demonstration board to get started.
A demonstration board, pictured right, has very
easy points to connect your lab scope. These
types of boards will let you simulate the testing
of injectors and sensors with the ability to
simulate a fault during the test.
Congratulations on purchasing this course and
taking the first serious step in learning how to
use the MTS 5200 lab scope.

HOW TO GET STARTE WITH YOUR LAB SCOPE (CONTINUE )
Another thing that you need to do is to use your lab scope to test known good vehicles. It is
critical that you do this because if you don’t, you will find that you will be trying to learn how to
use your lab scope while attempting to fix vehicles under pressure. This is the worst thing you
could possibly do. Take the time to practice with your lab scope on known good vehicles and
really learn how to connect, navigate and test BEFORE you start using it to fix vehicles in your
service bay.
While you are practicing on known good vehicles you should be documenting the actions that
you are performing with the tool. Start with something easy like a TP sensor or an O2 sensor and
keep good notes on how you test and the results you get. In the next few steps we will cover an
O2 sensor as example of what we are discussing.
O2 Sensor emonstration
In the screen capture to the left we have
chosen the 4 channel oscilloscope from the
main menu.
From the oscilloscope menu we have chosen
the Component Selection option from the left
side bar menu and the Sensors option from the
main Component Selection menu from the
center of the screen.

Once we have scrolled down to the O2 sensor
and selected it, the tool automatically sets
itself up to test O2 sensors.
From this screen you will be able to access
information on how to connect the scope to the
sensor, freeze the data on the screen, view
example O2 sensor waveforms and diagnosing
the signal.

Primary & Secondary Ignition
This portion of the presentation will cover how to navigate the MTS 5200 menu system and what
the menus are used for. Later on in the presentation we will cover the outside connections of the
lab scope and what they are used for.
It is important to note at this point that all of the features of the MTS 5200 are covered in
greater detail in the owners manual that came with the lab scope. Also, the manual can be
downloaded from the Bosch website at:

We have selected the analyzer utilities menu and you can see that there are three options
available. Setup, Tools and File Manager.
Once we have chosen the tools menu option, the Tools Menu will appear and as you can see in
the screen capture above there are a few choices we can make here as well. For this portion of
the demonstration we are going to choose Enable Ignition emonstration.
The Enable Ignition emonstration function allows for selection of a stored ignition waveform
program. This program operates in I Secondary Ignition, Secondary Quick Check, and Primary
Ignition.

This allows you to get better acquainted with the Engine
Analyzer controls, allowing for smoother operation when
hooked to a vehicle.
Once we have enabled the ignition demonstration we can
back out to the main menu and select Primary Ignition. In
the primary ignition function you will have the ability to
Choose Vehicle From atabase, Manual Vehicle Set-up
and/or Last Vehicle.
For this demonstration we will be choosing Manual Vehicle
Setup.
After selecting manual vehicle set-up we need to select the
ignition type. For our demonstration we will be using I
( ist. Ign.) External Coil. After making the selection
remember to click on the one option menu choice.
Next you want to Select the number of cylinders from the
Select Number of Cylinders menu. Engines with 2 to 12
cylinders are supported.
Select the correct firing order on the Select Firing Order
pop-up menu. The Page own and Page Up buttons move
you one complete page at a time, allowing faster access to
the firing order selections.
Choose firing order carefully, because selecting the
incorrect firing order causes mislabeled cylinders to display
incorrect data. Touch the one button to complete the
selection.

Once the firing order has been chosen, the ignition scope screen appears and is configured for
primary ignition. Notice that all eight cylinders are displayed in the correct firing order across the
bottom of the screen but the patterns for each cylinder are very small. This is because the
division on the screen is set at 50 V.
Pictured above is the same display but we have set the divisions to 10 V giving a more clear
picture as to what the primary ignition waveforms look like.

If you are in doubt about how the connections from the tool to the vehicle should be made, click
on the menu option “Lead Help” in the left sidebar of the screen. As you can see in the above
screen capture, a detailed schematic will appear on the screen giving you good direction on how
to make the connections.
The MTS 5200 has a set of trigger controls that determine the exact instant the trace begins the
sweep across the screen. If a trigger is set at a specific voltage level, and the signal being
sampled achieves that trigger level voltage, then the MTS 5200 displays the signal. When
triggering, a “T” appears in the small box at the left of the trigger settings box at the bottom of
the touch screen display.

While viewing live data, you can access all trigger properties through the Trigger Setup touch
screen display button to the left of the signal display area as illustrated in the screen capture
above. The 4-Channel Oscilloscope has the ability to use any one of four channels as the trigger
source.
For our demonstration we have chosen to locate the trigger on cylinder #8 as indicated in the
screen capture above.

Also in the main menu is a menu option called “Freeze”. The Freeze button is available any time
the MTS 5200 is collecting data in any of the display modes. The Freeze button stops the
collection of live data and freezes the signal on the display, allowing you to analyze the frozen
signal. Once the Freeze button is pressed, you are able to perform additional functions, such as
Save the frozen signal to memory.
Another great feature of the MTS 5200 is that you have the ability to select one of the cylinders
at the bottom of the screen and it will overlay the pattern above the firing patterns for the entire
engine. As you can see in the screen capture above, we have chosen the #3 cylinder and the
firing waveform has appeared above the parade pattern.
Selecting a single cylinder in this manner gives you the ability to get a closer look at the primary
charge, secondary kick, burn time and the coil oscillation at the end.

Superimposed isplay mode allows you to view the waveform of each cylinder in the firing order
on a single screen, simultaneously. Each cylinder waveform is positioned beginning with the
firing spike at the trigger position. The cylinder waveforms therefore overlap each other.
Selecting a cylinder from the Cylinder Selection buttons at the bottom of the touch screen display
causes the MTS 5200 to hide or display the selected cylinder. You may choose to display any
number of cylinders on the display at one time. oing this will help you to identify the cylinder
that is having the problem so you can further diagnose the fault.

Raster isplay mode allows you to view the waveform of each cylinder in the firing order on a
single screen, simultaneously. Selecting a cylinder from the Cylinder Selection buttons at the
bottom of the touch screen display causes the MTS 5200 to hide or display the selected cylinder.
You may choose to display any number of cylinders on the display, but the MTS 5200 always
takes into account the number of cylinders in the firing order and spaces the patterns so that all
cylinders are displayed on a single screen. You may change the spacing between the cylinder
waveforms using the Pattern Spacing touch screen button in the Setup menu. Pattern Spacing
affects all cylinders in the firing order and is not specific to your selected cylinders.

Bar Chart isplay mode allows you to view the voltage levels of each cylinder in the firing order
on a single screen. Each cylinder’s primary voltage is displayed in Bar Chart format so it is easy
to spot a cylinder voltage that does not compare with the others. All cylinders are displayed in
the correct firing order at all times.
The Firing Volts Barchart displays a bar graph showing the primary voltage required for each
cylinder. Live, Min (Minimum), Max (Maximum), and Avg (Average) values for each cylinder are
displayed. The numeric units are displayed in volts. The cylinders are listed in firing order
sequence.
• The Live data value is the same data displayed in the barchart format.
• The Min value is the lowest voltage value recorded for that cylinder.
• The Max value is the highest voltage value recorded for that cylinder.
• The Avg value is the average voltage value recorded for that cylinder.
Pressing the Reset button resets the Min/Max/Avg data.
It is important to note that the peak Kv firing line will be different for each cylinder and will
change as the engine runs. This is because the fuel mixture for each cylinder is different and is
being adjusted as the engine runs.
You want to keep an eye on the Avg. data. The Avg. is going to show you the average for all of the
cylinders over time. If you see one that is significantly higher or lower than all of the others, this
indicates that is the bad cylinder.

Secondary Quick Check
uring diagnosis of a secondary ignition system you might encounter situations where you want
to display information on one specific cylinder. A iagnostic Trouble Code ( TC) such as a P0302
(cylinder #2 misfire) would direct you immediately to the cylinder. Secondary Quick Check gives
you a quick and easy way to look at individual plug wires in the secondary ignition system by
simply hooking up one lead. The Secondary Quick Check utilizes a pre-configured display based
on the Secondary Ignition function.
The Secondary Ignition Lead is connected to the Sec Ign port on the tester and then clamped to
the plug wire. Connecting this lead directly to a plug wire will give you a cylinder ignition output
display on istributor ( I), istributorless (EI) and Coil-Near-Plug (CNP) systems. Be sure to
connect the secondary probe shield to a good engine ground.

Although the Secondary Quick Check is fully functional on istributor Ignition ( I) systems, some
applications filter the ignition signal as it passes through the distributor. This distorts the signal
at the individual spark plug wires. For this reason, Bosch recommends using the Secondary
Ignition Mode on istributor Ignition ( I) vehicles.

Graphing Multimeter is a powerful diagnostic tool that allows you to view circuit operation over
extended periods of time. All measurements are plotted horizontally from left to right to show
the measurement over time and vertically to display the measured value.
epending on the operating mode selected, the graphing multimeter can read C voltage, C
low current and C high current, frequency, pulse width, duty cycle, RPM, temperature, vacuum,
and pressure.

Graphing Multimeter
Graphing Multimeter displays data over extended periods of time giving you a better way to view
the data or a fault condition. For intermittent problems, simply connect to the suspect circuit and
monitor the plotted measurement by verifying glitches in the graph and/or look for higher than
normal min/max readings.
Graphing Multimeter helps you accurately evaluate automotive signals such as O2 Sensors,
MAF / MAP, IAT, Injector pulse width, EGR valve position sensor test, and TPS sweep test.
