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
4-20 mA Measurement Resolution
Data Acquisition > 4-20mA Current Loop Don’t overlook a vital component that affects 4-20 mA measurement success: Measurement resolution. Additional Reading: 4-20 mA Shunt Resistor and Current Loop Data Acquisition Products Measurements from sensors that have a 4-20 mA output are very common. Customers always ask how to connect them to a data logger or data acquisition Read More
How To Install Model DI-245 Under Windows XP
Data Acquisition > Voltage > DI-245 Since our new model DI-245 voltage, millivolt, and thermocouple data acquisition system was released after Microsoft very vocally discontinued support for Windows XP, the instrument is the first in a long while that does not natively support that operating system. We’ve since learned to our chagrin that Microsoft continues to Read More
Introducing the DI-245 Voltage and Thermocouple Data Acquisition System
Data Acquisition > Voltage > DI-245 DATAQ Instruments is pleased to introduce the all-new DI-245 Voltage and Thermocouple data acquisition system. The DI-245 provides four analog inputs that can be individually configured to measure voltage or thermocouple data. With 12 programmable measurement ranges from ±50V to ±10mV, the DI-245 provides resolution up to 1.2µV. The DI-245 Read More
Discontinued Support for Windows XP
Data Acquisition > Software > WinDaq As you may have heard, Microsoft has discontinued support for Windows XP, effective April 8th, 2014. After a 12-year run, Microsoft will no longer release updates or security patches for the widely embraced operating system. Consequently, DATAQ Instruments will also end support for Windows XP. While we will continue Read More
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
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
