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
Measurement Categories
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.

2.2. Drive installation
PCI-1132 data acquisition device can be used in Windows 7 and Windows 10, including
32-bit and 64-bit. Here, taking the driver installation in Windows 10 environment as an
example, we will introduce how to install the driver of PCI-1132 data acquisition device
step by step. The steps of installing drivers in Windows 7 environment are the same as
those in Windows 10 environment.
1) Open the device manager of Windows operating system, and when the driver is
not installed, it is displayed as "PCI Data Capture and Signal Processing
Controller", as shown in Figure 2.3 below.
Figure 2.3 Before the driver is installed

2) Select "PCI Data Capture and Signal Processing Controller", right-click and select
"Update Driver". Select "Browse my computer to find driver software" in the pop-
up dialog box, as shown in Figure 2.4 below.
Figure 2.4 Browse my computer for driver software

3) Then in the pop-up dialog box, click "Browse" button, locate the operating system
version folder corresponding to the driver, and then click "Next", as shown in
Figure 2.5.
Figure 2.5 Locate the folder where the driver is located.

4) The computer starts to enter the driver installation process. After the installation
is successful, the dialog box shown in Figure 2.6 below pops up, and the driver
installation is completed.

3. Digital Input（DI）
This chapter introduces the related contents of PCI-1132 data acquisition device used for
digital signal input.DI is the abbreviation of Digital Input here.
The circuit diagram of digital input is shown in Figure 3.1.

Figure 3.1, digital input circuit Figure
3.1. Digital sensitivity
The setting of digital input sensitivity is to filter the input level jitter of unpredictable
length, such as the jitter caused by button switch. Sensitivity is set in time units. For
example, the default value of digital input sensitivity of PCI-1132 is 20ms, and its
function mode is shown in Figure 3.2 below.
Actual input
Acquisition result
Figure 3.2 Schematic diagram of function mode of digital sensitivity
Take the default value of 20ms as an example. When PCI-1132 detects that the level of the
actual input port changes, it starts timing. When it reaches 20ms, it takes the current level
state of the actual input port as the acquisition result.

Attention
The number of set collection points cannot exceed 2MPts.
3.2. Signal acquisition mode
PCI-1132 data acquisition device supports the following three acquisition modes when
performing DI acquisition:
Continuous acquisition mode
Limited collection mode (OneShot mode)
Single read
The sampling rate of the first two modes adopts hardware timing.The limited number
acquisition mode is called OneShot mode.
Hardware timing
Hardware timing refers to the sampling rate of the sample acquired by DI. It is controlled
by the hardware digital signal (DI sampling clock).
Continuous acquisition mode
The continuous acquisition mode refers to continuous and uninterrupted data acquisition at
a set sampling speed.
In the continuous acquisition mode, after the DI acquisition triggers, the acquisition device
collects the signal at a fixed sampling speed, buffers it in the FIFO, and continuously
uploads the data in the FIFO to the computer memory buffer. The user program only needs
to continuously process the data in memory to achieve continuous uninterrupted data
collection.
If the user program could not process the data fast enough, the data will gradually fill up
the 2M points of storage space in the computer's memory buffer. After filling it up, the
new data cannot be written into memory buffer correctly, resulting in data discontinuity.
Limited number acquisition mode
Limited number of acquisition modes (OneShotmode) refers to one-time acquisition of the
set number of collection points at the set sampling speed.
In OneShot mode, after the DI acquisition triggers, the acquisition device will start
acquiring set number of data at the set sampling speed and stop the acquisition
automatically after. The user program only needs to read the set data amount from the
computer memory buffer.
Single read
Single read refers to reading the status of the current digital input port once. No trigger is
required for a single read.

3.3. Trigger
The PCI-1132 data acquisition device provides rich trigger options. The DI acquisition
trigger options are shown in Figure 3.3.
DoSoftTrig software trigger
Globa software trigger
DI trigger signal
Figure 3.3 DI trigger options
The DI acquisition uses the DiSoftTrig software trigger as the trigger source by default.
The DI acquisition can use other trigger sources via software settings to achieve the
synchronization of each function.
DiSoftTrig software trigger and Global software trigger are software triggers, which are
used to send a command to the acquisition device to initiate device triggering.
Clear Trigger
Trigger status can be reset to an untriggered state via software settings.

3.4. Counting edge
Counting edge means that every DI channel can count the edges on the DI input port, each
DI channel has a 32-bit counter, and each channel can independently set whether to count
the rising edge or the falling edge.
The schematic diagram of rising edge counting principle is shown in Figure 3.4.
Figure 3.4The schematic diagram of rising edge counting principle
Attention
Counting edge function is to make counting edge for the collected
results after digital input sensitivity filtering.
3.5. Interrupt
All DI input channels of PCI-1132 can be set as bit interrupt sources, and can also be set
as high-level interrupt or low-level interrupt at will.
Through the dll and functions provided by us, users can implement custom interrupt
service functions. Please refer to the corresponding routine for detailed usage methods.
