DATAQ Instruments Application Notes and News
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
EL-WIFI-Alert Alarm Indicator
Data Logger > Wireless > EL-WiFi Series The stand-alone EL-WIFI-Alert alarm indicator is an add-on for EL-WIFI series temperature and humidity data loggers. The EL-WIFI-Alert produces an audible and visual alert when an alarm level on any of your EL-WIFI temperature and humidity data loggers (installed on the same wireless network) is breached. Note that 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
