About the DAQMeter DAQCard-4050
Thank you for buying a National Instruments DAQMeter
DAQCard-4050. The DAQCard-4050 is a digital multimeter card
for computers equipped with Type II PCMCIA slots.
The DAQCard-4050 features accurate 5 1/2-digit
DC voltage, true
root mean square (RMS) AC voltage, ohm, and diode measurements
in a PC Card format. You can use the card to make the same
measurements you would with a standard benchtop digital multimeter.
The DAQCard-4050 contains a 24-bit analog-to-digital converter
(ADC) with digital filtering, which gives the card excellent resolution,
accuracy, and noise rejection. Coupled with a CSM series current shunt
module available from National Instruments, the DAQCard-4050 also
effectively measures AC and DC current.
The DAQCard-4050’s small size, weight, and low power consumption
make this device ideal for use in portable computers, which makes
remote measurements and data-logging practical. The DAQCard-4050
requires very little power when in operation, thus extending the life of
your computer batteries.
A system based on the DAQCard-4050 offers the flexibility,
performance, and size that makes it ideal for service, repair, and
manufacturing as well as for use in industrial and laboratory
environments. The DAQCard-4050, used in conjunction with your
computer, is a versatile, cost-effective platform for high-resolution
measurements.
Detailed specifications for the DAQCard-4050 are in Appendix A,
