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
www.autoscope.eu

USB Autoscope III
- 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.

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" software appears, agree and install
the suggested program.
Installation of the "Adobe Reader" program may take several minutes.

3.3 Installation of the device drivers
Connect the device to USB 2.0 480 Mbit/s (HI-SPEED) port of the laptop or PC only after
installation of USB Oscilloscope software.
Right after connection of the device to a USB 2.0 480 Mbit/s (HI- 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 2.0 A/B interface cable.
The computer must have Microsoft Windows XP SP2 or higher operating system and have
the USB Oscilloscope software installed.
The black alligator clips from the USB Autoscope III's oscilloscope probes, cables and
adapters must be connected to vehicle ground on the diagnosed vehicle (if an older vehicle,
use the engine ground) at only one point.
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 mm2, 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 III using a separate multi stranded copper wire with
a cross section of more than 0.5 mm2.

6. Manufacturer limited warranty
The manufacturer guarantees the performance of components supplied with the
USB Autoscope III during their warranty period.
Warranty period for the main unit USB Autoscope III is 24 months from the date of sale,
for transducers Px and Dx - 12 months.
During the warranty period, the manufacturer will at their discretion, replace or repair
components that failed due to a manufacturing defect or during normal use. Failures caused
by abuse or neglect, are not covered.
This warranty gives you specific legal rights and you may have other rights that vary, depending
on where you reside.
7. Troubleshooting
7.1 The device does not turn on
The device is not connected to USB 2.0 480 Mbit/s (HI-SPEED) port of the host computer.
Connect the device to USB 2.0 480 Mbit/s (HI-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 2.0 A/B interface cable of no more than
3 meters in length and with a label stating "CERTIFIED HI-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 2.0 480 Mbit/s (HI-SPEED) port of the personal computer is broken.
Try another port or computer.
The USB 2.0 480 Mbit/s (HI-SPEED) port of the personal computer does not provide
enough current.
While in operate mode the current consumption does not exceed 350 mA which is well
below the maximum allowable 500 mA for USB devices. However, some computers does not
provide the required current. One of several possible reasons is a malfunction
of the USB port's supply circuit. Try another port, or try to connect to a powered USB hub.
The PC or laptop's power settings may have been set to limit the current available
to the USB port. Try changing power settings, or use a powered hub.

7.2 "USB transfer error"
If in the process of working with the device in the USB Oscilloscope window the message
USB transfer error message 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 mm2.
Used faulty, low-speed or too long USB cable.
Change the USB cable to a quality high-speed USB 2.0 A/B interface cable of no more
than 3 meters in length and with a label stating "CERTIFIED HI-SPEED USB".
