DATAQ Instruments Application Notes and News

Error Binding UDP Port 1234

Data Acquisition > Ethernet It’s come to our attention that some DI-720/730 Ethernet users are having trouble communicating with their instruments. Upon running the DATAQ TCP/IP Manager, users receive an error message stating that there is an “Error Binding UDP Port 1234” and that the IP Manager cannot continue. We are working hard to determine Read More

Boot Your Graphtec Data Logger in USB Drive Mode

Data Logger > USB > Graphtec An oft-overlooked feature of Graphtec data loggers is the ability to boot into USB Drive Mode. As the name implies, USB Drive Mode allows you to access, save, copy and delete files from your GL220, GL820, GL900, GL7000 or MT100, just as you would with a USB flash drive. Read More

Sample Up to 14.4 kHz in Stand-alone Mode

Data Logger > Stand-alone Thanks to single-level cell (SLC) technology, DATAQ Instruments stand-alone data loggers can once again sample at throughput rates up to 14,400 samples per second. Due to inconsistencies with older SD cards using multi-level cell (MLC) technology, we were forced to reduce the maximum stand-alone sample rate specification for DATAQ Instruments data Read More

Acquire Data in Minutes

Data Acquisition > Software > WinDaq WinDaq data acquisition software allows you to acquire data in minutes! So you’ve chosen a DATAQ Instruments data acquisition system or data logger, you’ve connected the instruments to your PC, and you’ve successful installed the software. Now what? How do you record data? WinDaq data acquisition software allows you Read More

Save a Segment of Data as a Second, Smaller File

Data Acquisition > Software > WinDaq   The WinDaq Waveform Browser allows you to select a segment of data, and save it as a second, smaller file. Suppose you have a very large data file, recorded over several days, or even weeks. Now suppose that that file contains a significant event that transpired in a matter of Read More

Data Logger vs. Data Acquisition

Data Acquisition or Data Logger If you need to digitize an analog signal, record it, and provide a method to analyze it, do you need a data logger or a data acquisition system? It has become increasing clear that the answer is ‘Yes’ to both products. What I mean is that the traditional definitions of Read More

How To Measure Current

Data Acquisition > 4-20mA Current Loop …current is always measured indirectly from an external sensor that produces a voltage output that is proportional to current. Since the only difference between a voltage and current measurement is the scaling that you apply to the result, voltage measuring instruments are almost always used to measure current.   Read More

WinDaq System Used in Bridge Monitoring

Data Acquisition > Ethernet > Distributed Synchronous The I-35W Mississippi River Bridge in Minneapolis, MN connects Downtown East to Marcy-Holmes. Following its catastrophic failure on August 1, 2007, a decision was made to rebuild the bridge with a state-of-the-art monitoring system. The contractor chose DATAQ Instruments hardware and software for the job due to our expertise Read More

FFT (Fast Fourier Transform) Waveform Analysis

Data Acquisition > Software > WinDaq To calculate an FFT (Fast Fourier Transform), just listen. The human ear automatically and involuntarily performs a calculation that takes the intellect years of mathematical education to accomplish. The ear formulates a transform by converting sound—the waves of pressure traveling over time and through the atmosphere—into a spectrum, a Read More

Three Easy Steps for Stand-alone Data Logging Using a DI-71x Data Logger

Data Logger > Stand Alone Configure Connect a Data Logger to the USB or Ethernet port of your PC and run the provided set up software. Configure the data logger for your specific requirements in the following ways: Enable or disable specific analog channels in any order. For enabled channels define input configuration (single-ended or Read More
