Safety 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 Categories
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 (C AT 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.

data acquisition device.
2.1. Connector signal pins distribution
Figure 2.1 USB-3200 signal pins distribution
Attention When USB 3200 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

14 |
same terminal, otherwise it will cause a measurement error.

2.2. USB cable reinforcement design
USBcable connectors are prone to be pulled off during operation. USB-3200series 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. Driver installation
Smacq USB-3200series data acquisition device support Microsoft Windows XP,Windows 7,
Windows 8/8.1,and Windows 10, including all the 32-bit and 64-bit versions.Toinstall the
driver for USB-3200 devices, you need to turn off driver signature enforcement first.
Here is an example step-by-step tutorial on howtoinstall the driver in Windows 7.

16 |
1) Connect your USB-3200 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-up dialog box, select “Browse my computer for driver software”
4) And then select “Let me pick from a list of device drivers on my computer”
5) Click on “Next” and then select “Have disk”
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.

series data acquisition devices.AI here isshort for Analog Input.

3.2. Signal connection methods
USB-3200 series 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

3.3. Floating grounded signal source
A floating grounded signal source is not connected in any way to the building ground system but,
it has an isolated ground-reference point. Common floating grounded signal sources are
transformers, thermocouples, battery equipment, optical isolators, and isolation amplifier output.
An instrument or device with isolated output is a floating-ground signal source.
Attention When measuring the floating ground signal source, it is important to
connect the negative end of the signal source directly or indirectly
through the resistor to the AGND。
Using differential mode (DIFF) connection
When any of the following conditions are true, a differential mode should be used to connect the
floating signal:
Analog input AI+ and AI- are all valid signals.
Low input signal voltage while higher accuracy demanded
The cable length ofthe connection signal to the acquisition device exceeds 3meters
The input signal requires a separate ground-reference point or a return signal
There is obvious noise in the environment of the connection wire
Differential connectionmode can reduce noise interference and improve the common-mode
suppression ability of acquisition device.
For a floating signal source with lessthan 100ΩF internal resistance, you can directly connect the
negative endof the signal toAI- and AI-GND ports and connect the positive end ofthe signal to
AI+ ports,asshown below in figure 3.2.
