DATAQ Instruments Application Notes and News

Using Intelligent Oversampling to Extract Important Information

Data 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

EL-USB Battery Issues

Data Logger > USB > EL-USB 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 Read More

Sub-zero Thermocouple Measurements

Data Logger > Thermocouple “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 Read More

How To Power Multiple 4-20 mA Sensors

Data Logger > 4-20mA Process Current 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 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

Changes to the Built-in Temperature Alert Server

Data Logger > Wireless > Temperature Alert There have been some changes to the server, built into the Temperature Alert TM-WIFI350 LAN-based temperature and humidity data logger. In the past, when typing the IP address of your TM-WIFI logger into a web browser, you were directed to ‘Developer Mode’. In Developer Mode you can set alarms, Read More

Flood Sensor for Temperature Alert

Data Logger > Wireless > Temperature Alert The AC-FLDRJ is a flood sensor designed for use with the Temperature Alert TM-WIFI-350 LAN-based temperature and humidity data logger. Measuring just 2.5” x 3.25” x 1”, simply lay the sensor on a flat surface to detect the presence of conductive, non-flammable liquids. Built-in feet on the bottom 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
