About the Product
This product is a digital multi-meter board for PCI bus, which has 51/2 digits high precision, and has 2
channel simultaneous measurement function. It possesses five measurement functions that are direct
current voltage / current measurement, alternating current voltage / current measurement, resistance
measurement.
Collect data from personal computer directly, which contribute to largely shortening of tact time,
miniaturization of examination device, cost reduction. The maximum conversion speed is 1500SPS, so
it is possible to continuously sampling by 2 channels at the same time. The precision, integral time,
sampling interval can be set by software.
The digital multi-meter of bench
top type attaches to the application software [Front Panel Software]. It can be
used as a Voltage/Current/Resistance measurement instrument.
Windows API
is also attached
, so it is possible to
program by Visual Basic and Visual C++.
Features
Miniaturization of examination device / Cost reduction
The function of high precision digital multi-meter is realized by
the expansion board of personal computer. Examination devices
can be gathered into one personal computer,
measurement
instruments and
expansion boards for communication are not
necessary.
Largely shortening of tact time because directly controlled by personal computer
Compare with the system which use a
measurement instrument
and
a personal computer, the transmission time from
measurement
instrument to
personal computer and the communication
processing are reduced. Directly collect from personal computer
can be judged immediately, so the tack time for examining is
largely shortened.
[ The
essential time for collecting 10,000 data ]
51/2 digits high precision, 2 channel simultaneous measurement function
24bit ΔΣ Model A/D Converter is used, it is possible to measure (direct current voltage / current,
alternating current voltage / current, resistance (only channel 1)) by maximum 51/2 digits. It is insulated
between 2 channels. Therefore, even if there is a potential difference between channels, it is possible to
measure simultaneously for 2 channels. And, continuously sampling can be realized with the maximum
conversion speed that is 1500SPS * 2 channels.

DMM-552-PCI
[Front Panel Software] is used as a
digital multi-meter
The digital multi-meter of bench
top type attaches to the
application software [Front Panel Software], which can be used as a
Voltage/Current/Resistance measurement instrument. And, this
application has the function of diagnosing and reporting the state of
the board and device driver, so it can be used for make sure of the set
up execution environment.
The Function of Level Judgment
Set a threshold level beforehand. Level can be judged without software. Load of CPU can be reduced.
The types of threshold are OverRange, UnderRange, InRange, OutRange.
The Synchronization Control Connector for Synchronization Movement
In order to synchronization control maximum 16 boards, this board has a synchronization control
connector. Therefore channels can be easily added only by adding boards. And, this board can work
together with the others expansion board of our company which has a synchronization control connector.
Such as analog I/O board, digital I/O board, counter board etc. Advanced real-time control can be
performed without software.
The Function of Auto Range
The function of auto range is that select the most suitable range automatically according to the input
signal size. Therefore, when the signal which’s size can not be distinguished is input, a measurement
can be performed without range setting.
Select a Input Impedance from 10MΩ or more than 10GΩ
In the case of direct current voltage, range is 10V or 1V or 100mV, the input impedance can be selected
from 10MΩ or more than 10GΩ. If you want to reduce the noise influence, select 10MΩ. If you want to
reduce the influence of signal source’s output impedance, select more than 10GΩ. Therefore, the
measurement can be performed according to the measurement environment.
Software Trigger, Analog Edge Trigger, Hysteresis, Window Trigger, Digital Edge Trigger, Sampling
Start / Stop condition of Event Control Output etc.
The control of sampling start can be selected from software trigger, analog edge trigger, hysteresis,
window trigger, digital edge trigger, event control output. The control of sampling stop can be selected
from software trigger, sampling times stop. The control of sampling start and sampling stop is
absolutely independent. It can be individually set.
Use BNC Connector for Measurement Terminal
Use BNC connector for measurement terminal. It is easy to connect to the device which has BNC
connector.
Windows compatible driver library API-PAC(W32) cTEST is attached.
Using the attached driver library makes it possible to create applications of Window.
