DATAQ Instruments Application Notes and News

Save Select Channels as a New WinDaq File

Perhaps you’re using WinDaq data acquisition software to record a file containing 10 or 20 channels of data. Now suppose you’re sending that file to a colleague, who is really only interested in two of those channels. Your colleague now has to dig through the file, looking for the information that he or she is Read More

Transmitting Data From Your EL-WIFI Series Data Logger

Data Logger > Applications > Wireless Data Loggers > Transmitting Data From Your EL-WIFI Series Wireless Data Logger There’s been some confusion with with regard to EL-WIFI series data loggers and the way that they transmit temperature & humidity data back to the PC. In order for an EL-WIFI series logger to remain connected and continually Read More

Dual-Channel Wireless Temperature Data Loggers

DATAQ Instruments is pleased to introduce the EL-WIFI-DTC and EL-WIFI-DTP+. These dual-channel wireless (802.11b compliant) temperature data loggers are capable of buffering over 1,000,000 temperature readings and transmitting that data to a PC via a WiFi router. The EL-WIFI-DTC can acquire temperature from -270 to 1300°C (-454 to 2372°F) using J, K, N or T-type Read More

Using Intelligent Oversampling to Extract Important Information

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 DC equivalent or frequency, for example). Read More

Starter Kit Helps Win Science Fair Competition

DATAQ Instruments makes data acquisition hardware 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 high school students used WinDaq high-speed software that we donated with one Read More

EL-USB Battery Issues

We’ve noticed an uptick in the number of customers reporting that the batteries included with their EL-USB series data loggers are ‘dead on arrival’. The battery included with most EL-USB series loggers is a 3.6V (½AA cell) lithium metal battery. The problem can occur when a battery is unused for extended periods of time, like Read More

Sub-zero Thermocouple Measurements

“One of the best kept secrets in the instrumentation world is that sub-zero thermocouple measurements require thermocouples that are specially qualified for that application.” Looking at the specs of a typical thermocouple data acquisition system might be a little misleading when it comes to interpreting temperature measurement capability. For example Figure 1 is a snap-shot of the thermocouple Read More

How To Power Multiple 4-20 mA Sensors

We’re often asked how to power multiple 4-20 mA sensors using a single power supply. While it is possible to do this, the usual cautions apply regarding ground loops and other subtleties. Readers who are new to measurements using sensors with 4-20 mA process current outputs should refer to our earlier article that explains basic concepts Read More
