Security Requirements
Warning
Only the voltage within the specified range can be connected.
Voltage exceeding the specified range may cause damage to the
device, and even present a negative impact on personal safety. Check
the product specification for detailed reference to the range of
voltages that can be connected by each port.
Warning
Do not attempt to operate the device in other ways that are not
mentioned in this document. Incorrect use of the device may be
dangerous. In the event of device damage, the internal security
protection mechanism will also be affected.
Warning
Do not attempt to replace device components or change devices in
other ways that are not mentioned in this document. Do not repair
the device yourself in the event of a product failure.
Warning
Do not use the device in an environment where an explosion may
occur or where flammable flue or gas is present. If you must use the
device in this kind of environment, please fit it into a proper case.
Warning
While the device is running, all chassis covers and fill panels need to
be closed.
Warning
For equipment with exhaust vents, do not insert foreign objects into
the vents or block air circulation in the vents.

Measurement Category
Warning
For use in measurement category I (CAT I) only. Do not use in
measurement category II/III/IV. Use this device to connect signals or
make measurements.
Measurement categories Note
Measurement categories I (CAT I) means that measurements are made on a circuit that is not
directly connected to the main power supply. For example, a circuit that is not exported from
the main power supply, especially a circuit that is exported from a protected (internal) primary
power supply, is measured. In the latter case, the instantaneous stress will change. Therefore,
the user should be aware of the instantaneous affordability of the device.
Measurement categories II (CAT II) means that measurements are made on a circuit that is
directly connected to a low-voltage device. For example, a measurement on household
appliances, portable tools and similar equipment.
Measurement categories III (CAT III) means that measurements are made in construction
equipment. For example, a measurement on the distribution boards, circuit breakers, wiring
(including cables, Busbars, junction boxes, switches, sockets) in fixed equipment and
equipment for industrial use and certain other equipment (for example, fixed motors that are
permanently connected to fixtures).
Measurement categories IV (CAT IV) means that measurements are made on the source of
low-voltage equipment. For example, a measurement on a meter, a major overcurrent
protection device, and a pulse control unit.

Pollution level explanation
Pollution degree 1: No pollution, or only dry non-conductive pollution. This pollution level has no
effect. For example: a clean room or an air-conditioned office environment.
Pollution degree 2: Generally, only dry non-conductive pollution occurs. Temporary conduction
can sometimes occur due to condensation. For example: General indoor environment.
Pollution degree 3: Conductive pollution occurs, or dry non-conductive pollution becomes
conductive due to condensation. For example, an outdoor sheltered environment.
Pollution degree 4: Permanent conductive pollution caused by conductive dust, rain or snow. For
example: outdoor places.
Recycle precautions
Warning Some of the substances contained in this product may be harmful to the
environment or human health. In order to avoid releasing harmful
substances into the environment or endangering human health, it is
recommended that appropriate methods be used to recover this product
to ensure that most materials can be properly reused or recycled. For
information about processing or recycling, please contact your local
professional organizations.

Precautions
To prevent electrostatic discharge (ESD) from damaging the device, please note the following:
Please wear a grounding wristband or touch a grounded object first to ensure being
grounded.
Before removing the equipment from the packaging, please first connect the anti-
static packaging to the grounded object
Do not touch the exposed pins of the connector.
Place your device in anti-static packaging when you are not using the device.
Check the packing list
After unpacking the product, follow the packing list in the box, check the host and each
attachment individually to ensure that the items in the box are consistent with the packing list.
If you find that any item is missing, please get in touch with us for help as soon as possible.
If you find that the product comes in damaged after unpacking, please get in touch with us as
soon as possible. Do not install damaged equipment on your devices.

Attention When USB 3300 DAQ card is connected with a single-ended
connector via analog input, AI SENSE should only be connected
to the terminal of the group in which the channel is located, that
is, the positive and negative ends of the measured analog signal
should be connected to the same terminal, otherwise it will cause
a measurement error..

2.2. USB Cable Reinforcement Design
USB cable connectors are prone to be pulled off during operation. USB-3300 series data
acquisition devices provide a cable reinforcement design, with which a strap can be used to
fix the USB cable to the device to prevent the accidents. Check Figure 2.2 for details.
Figure 2.2 USB cable reinforcement design
2.3. Drive Installation
Smacq USB-3300 series data acquisition device support Microsoft Windows XP, Windows 7,
Windows 8/8.1, and Windows 10, including all the 32-bitand 64-bitversions. Toinstall
the driver for USB-3300 devices, you need to turn off driver signature enforcement first.
Here is an example step-by-step tutorial on how to install the driver in Windows 7.
1) Connect your USB-3300 card to the computer and launch the Device Manager in
Windows.
2) There should be a device with an exclamation point.
Right-click it, select “Update driver”.
3) In the pop-updialog box, select “Browse my computer for driver software”
4) And then select “Let me pick from a list ofdevice drivers on mycomputer”.
5) Click on“Next” and then select “Have disk”.

19|
6) Click Browse in the pop-up dialog box, then enter the \USB-3000SeriesDAQ\driver
folder in the CD-ROM, then enter the "win7" folder, then the 32-bit operating system
enters the "x86" folder, the 64-bit operating system enters the "x64" folder, select the
"susb.inf" file, and then click "Open". (The drivers of Windows8/8.1 and Windows10 are
the same as those of Windows7, using the same file. )
7) Then in the dialogue of “Install from disk”, click on “Yes”.
8) Click “Next”, if the Windows security warning pops up, you need to select “Install this
driver software anyway” to finish the installation.
After these steps, the operating system will start installing the driver, which usually takes
about 30 seconds. After the driver is installed, the exclamation point in Device Manager will
disappear, as shown in the following Figure 2.3.
Figure 2.3 the Device Manager after the driver is correctly installed

3.2. Signal Connection methods
USB-3300series data acquisition devices support analog input acquisition connection
methods of non-grounding reference single-ended input (NRSE) and differential input
(DIFF).
Table 3.1 lists the recommended connection methods for floating-ground signal sources and
grounding signal sources
