1, 3 Connections "In+" and "In–" are used for connection of high voltage probes.
The signals from the high voltage probes are inversely summed and go to the analog
input 8.
2Connection "In Synchro" is used for the synchronization (trigger) transducer that is used
to detect ignition spark. The signal from the transducer goes to the analog
input 7 through a peak detector.
4Device ground connection. Used to connect device ground to vehicle ground on the
diagnosed vehicle.
5, 6 Pulse polarity indicator from synchronization transducer.
7USB connection. Used for connection of the USB Autoscope Lite
to USB .0 1 Mbit/s (Full-SPEED) port of a laptop or PC. The connection uses a
USB .0 type A-B cable.

2.7 Ground cord
Signal measurements on the analog inputs of the USB Autoscope Lite are recommended to
perform relatively to the black alligator clip of the ground cord. Therefore, before starting the
measurement, the cable must be connected to the back of the device connector (ground) and the
black alligator clip must be connected to vehicle ground on the diagnosed vehicle. When
working with high-voltage probes, this connection is necessary.
In case of breakage of the cable, it can be repaired or manufactured according to the
diagram below.

3.2 Installation of the USB Oscilloscope program and utilities
Insert the installation CD disc in the optical disk drive of the computer.
If the notification "Tap to choose what happens with this disk" appears, left-click
the message screen.
Choose the option "Run setup.exe".
If after inserting installation CD in the optical disk drive of computer nothing happens,
browse through the disc and open the program setup file, called "Setup.exe". The drive letter
your computer uses for the optical drive, often D:\Setup.exe or E:\Setup.exe
http://usbautoscope.eu/ 8
USB Autoscope Lite – Operation Manual
If a pop up about unknown publisher of "setup.exe" appears, click "Yes".
You may have to wait while the installer verifies.
In the window "Installer Language", change the installation language if desired.
Then, follow the installation instructions, changing parameters only when required.
http://usbautoscope.eu/ 9
USB Autoscope Lite – Operation Manual
In window "Windows Security" activate option "Always trust software from…" then
press button "Install".
If the message "Windows can't verify the publisher of this driver software" appears,
choose the option "Install this driver software anyway".
If a message about the need to install "Adobe Reader" or "Adobe Flash Player ActiveX"
software appears, agree and install the suggested program.
Installation of the additional software may take several minutes.

3.3 Installation of the device drivers
Connect the device to USB .0 1 Mbit/s (Full-SPEED) port of the laptop or PC only after
installation of USB Oscilloscope software.
Right after connection of the device to a USB .0 1 Mbit/s (Full-SPEED) port
the installation of drivers will start automatically.
After successful installation the user will get an installation report.

4. Preparing the device for use
The device connects to a laptop or PC's USB port using a USB .0 A/B interface cable.
The computer must have Microsoft Windows XP SP or higher operating system and have
the USB Oscilloscope software installed.
Before the measurements, the black alligator clip from the USB Autoscope Lite's ground
cord must be connected to vehicle ground on the diagnosed vehicle. The preferred
connection point is a vehicle body ground on the diagnosed vehicle. If an older vehicle,
use the engine ground. The signal measurements on the analog inputs are relative to vehicle
ground, because the vehicle ground is connected to the common ground of the device
through the black alligator clip of the ground cord.
Note that in some cases signal ground and ground of vehicle body are not at the same
potential. One example would be Lambda or Oxygen sensor ground on GM vehicles. This
can skew voltage readings if not taken in to account. In such cases a differential mode can be
used, connect one channel to the signal and another channel to the signal ground.
The device and it's cables must be placed as far as possible from the high voltage wires
of the ignition system, the exhaust manifold, and the cooling system fan.
The computer itself must be grounded using a separate multi stranded copper wire
with a cross section of more than 0.5 mm , otherwise a failure of the computer or device
is possible. If a laptop running on its internal battery and with the main power supply
disconnected is used, this requirement is unnecessary.
In order to avoid distortion and / or damage to the data that are sent via the USB interface,
due to electromagnetic interference from the vehicle's ignition system, it is recommended
to ground the USB Autoscope Lite using a separate multi stranded copper wire with
a cross section of more than 0.5 mm .

6. Troubleshooting
6.1 The device does not turn on
The device is not connected to USB .0 1 Mbit/s (Full-SPEED) port of the host computer.
Connect the device to USB .0 1 Mbit/s (Full-SPEED) port of the host laptop or PC.
Faulty, low-speed or too long USB cable.
Change the USB cable to a quality high-speed USB .0 A/B interface cable of no more than
3 meters in length and with a label stating "CERTIFIED Full-SPEED USB".
The driver for "Universal Serial Bus controller" is not installed.
Install the drivers for the motherboard that is in your computer.
The USB .0 1 Mbit/s (Full-SPEED) port of the personal computer is broken.
Try another port or computer.
6.2 "USB transfer error"
If in the process of working with the device in the USB Oscilloscope window the message
USB transfer error appears, it indicates distortion and/or damage to the data that are sent via the
USB interface.
The device and / or its USB cable placed too close to the source of electromagnetic
interference.
Ground the device using a separate multi stranded copper wire with a cross section
of more than 0.5 mm .
Used faulty, low-speed or too long USB cable.
Change the USB cable to a quality high-speed USB .0 A/B interface cable of no more
than 3 meters in length and with a label stating "CERTIFIED Full-SPEED USB".
