RSS FeedsData Acquisition > Software > WinDaq Oversampling is a feature whereby a data acquisition instrument can sample data at a faster rate than what is being reported in the software. Intelligent Oversampling allows the instrument to evaluate the data that isn’t being reported, and yield just the information you’re looking for (average, maximum, minimum, the Read More

DAQ Starter Kit Helps Win Science Fair Competition
Data Acquisition > Start Kits DATAQ Instruments makes data acquisition hardware (usually a DAQ starter kit) and software donations from time to time to young people who demonstrate the need for a particular measurement that we can satisfy. Examples are measurements in school projects, science fairs, and even Ph.D theses. We recently learned that two Read More
Active USB Extension Cables Limit Data Loss
Data Acquisition > USB Perhaps you have an application that requires your USB-connected data acquisition system to be positioned further from the PC than the 2 to 5 meter maximum USB cable length specification. The USB Active extension cable allows you to position your USB-connected data logger up to 15 meters (almost 50 feet) from Read More
Trouble Communicating With Your Ethernet Connected DI-720 or DI-730 EN-B
Data Acquisition > Ethernet On This Page Symptoms Cause Resolution Verify that you’re installing the latest version of WinDaq Verify that your Network Interface Card (NIC) has a static IP address Disable any wireless connections Verify Windows Firewall settings Run the DATAQ IP Manager as an administrator Make sure that your Ethernet cables are not Read More
Die Cushion Qualification
Data Acquisition > Mixed Measurements DATAQ Instruments was recently mentioned in Evaluation Engineering magazine‘s special report on data acquisition systems. The feature focused on applications in machine condition monitoring, which is an area that is very popular for users of our equipment. So, we thought we’d publish an overview of it here for our readers. The specific Read More
WinDaq/XL Real-time Bridging Software
Data Acquisition > Software > WinDaq > Add-ons WinDaq/XL is real-time bridging software that allows users to stream data from WinDaq data acquisition software or the WinDaq Waveform Browser, into a Microsoft Excel spreadsheet. Once there, users can take full advantage of Excels exceptional ability to perform calculations and chart data. Since it’s initial release Read More
WiFi Range Considerations
Data Logger > Wireless We carry several WiFi products and we’re often asked about their range. In other words, how far from the WiFi router can the data loggers be located? Unfortunately, this is like asking us to forecast the weather next Sunday. There are simply too many variables for us to predict how well any WiFi Read More
Why You Need Channel-to-channel Isolation
Data Acquisition > Voltage > DI-245 Editor’s update: All information in this application note applies equally to model DI-808 data logger with a built-in Web server, and model DI-2008 Thermocouple, Voltage and Pulse Data Acquisition System. It’s difficult to temper excitement about DATAQ Instruments’ model DI-245 data acquisition system. Beyond thermocouple-based measurements and a superb voltage measurement Read More
How To Calculate Common Mode Rejection Ratio
Data Acquisition > Voltage > DI-245 Common Mode Rejection Ratio Defined Editor’s update: All information in this application note applies equally to model DI-808 data logger with a built-in Web server. Common mode rejection ratio doesn’t seem at all common. In fact, it sounds rather fancy and complicated. But it’s actually a simple concept. Recall Read More
The Ability of the DI-245 and DI-2008 to Reject Common Mode Voltage
Data Acquisition > Thermocouple > DI-245 The ability of the DI-245 and DI-2008 to reject common mode voltage is unmatched in the $75 per channel price range. To demonstrate the ability of the DI-245, where DI-2008 shares the same front-end configuration, to reject common mode (error) voltage, we connected K-type thermocouples to channels 1 and Read More
