DATAQ Instruments is happy to introducing the all-new EL-USB-TP-LCD, a single–channel thermistor data logger. With a -40 to +125°C (-40 to +257°F) measurement range, the included 1-meter thermistor probe has an accuracy of ±0.1°C (±0.2°F). Capable of storing up 32,510 readings, with sample intervals ranging from 1 second to 12 hours, the EL-USB-TP-LCD can acquire temperature data, unattended, for months, or even years. Programmable alarms allow you to illuminate a LED when temperatures rise above or fall below user-defined levels, and a high-contrast LCD display allows you to view the current temperature, the maximum logged temperature or the minimum logged temperature.
The included EasyLog USB software gives you the ability to configure the EL-USB-TP-LCD (choose a sample interval, set alarm levels, etc), download and display (graph) acquired data, or save data in Microsoft Excel format.

Ask customers what they want to do with acquired data, and the vast majority answer, “Take it to Excel.” Although our WinDaq Playback software has always supported an Excel-compatible CSV export option, the process was cumbersome and not very flexible. We fixed that.
DATAQ Instruments is proud to announce the beta release of a new built-in utility to WinDaq Waveform Browser called “WWB to Excel.” The Export-to-Excel utility is easily accessible via the File menu. It’s simple to use and offers some great features for data export and format including precise data selection with the time marker and cursor, time stamp options for relative time as well as local time, event marker options, workbook and worksheet names and files, start cell declaration, user annotation, comments, engineering units, and sample rate.
The utility doesn’t just run in the background and spit out a saved file – it works in real time and provides a back button that allows you to change any of your export options. There are no secondary files. The export utility opens Excel and you save the file from Excel when you are happy with the export data.
Download it, take it for a test drive, and let us know what you think in the comments below. Compatibility is Microsoft Excel 2003 and up. WinDaq Waveform Browser is free software.

DATAQ Instruments is pleased to introduce the all-new EL-GFX-DTP dual-channel thermistor data logger, with a -40 to +125°C (-40 to 257°F) measurement range. Capable of storing up to 250,000 readings at sample intervals between 2 seconds and 1 hour, the EL-GFX-DTP can acquire temperature data, unattended, for days, weeks, months or years. Programmable alarms allow you to illuminate LEDs and/or sound audible alarms when temperatures rise above or fall below user-defined levels.
Downloadable EL-WIN-USB software allows you configure the EL-GFX-DTP (choose a sample interval, set alarm levels, etc), download and display (graph) acquired data, or save data in Microsoft Excel format.

DATAQ Instruments is pleased to announce the availability of the all-new EL-USB-ACT. This low cost AC/DC current data logger is capable of taking current readings from 0 to 100 Amps DC (0 to 723 amps RMS) and can be used with a compatible current clamp, current transformers, hall-effect current sensors, or connected directly across a shunt. The stand-alone logger, power by two replaceable AA batteries, can acquire 127,000 readings over wide range of sample intervals, from 1 second to 12 hours.
The EL-USB-ACT includes EL-Win-USB software, for configuration, data retrieval and data analysis.

We’ve touched on several features of Advanced CODAS, demonstrating the ease with which you can integrate, differentiate, and peak detect waveforms without leaving the WinDaq Waveform Browser.
In this example we’ll break down a real-world application, demonstrating how several Advanced CODAS functions are used in concert to derive and report the time between the rising edges of individual pulses in a pulse train.
When integrating a waveform using Advanced CODAS, the Periodic Reset feature allows you to reset the integral function after a user-specified period of time (number of data points).
In this example, featuring the new Advanced CODAS user interface (in beta), we’ll integrate a flow rate waveform and perform a periodic reset every five seconds. Doing so allows us to determine flow volume (total flow) after each five second interval.
The ‘Integral’ function in Advanced CODAS alloys you to perform a level reset when integrating a waveform.
In this example we’ll integrate a flow rate waveform to derive flow volume, and reset the integral function at a specific level (3 gallons in this case). Resetting the integral function (flow volume calculation) allows users to determine the time taken to reach a particular flow volume.
It’s come to our attention that there’s some confusion when it comes to enabling a digital channel and displaying digital input in WinDaq Data Acquisition Software.
In this example, we’ll enable a digital channel, and show how digital inputs are displayed.
