RSS FeedsOften, you’ll need to acquire signals at very high sample rates. Higher sample rates allow you to capture voltage transients, or events that occur in a very short period of time. And since all channels in WinDaq are sampled at the same rate, you might get the results you’re looking for on some channels, and Read More
DATAQ Instruments Application Notes and News
Using the Time Marker and Cursor for Data Analysis
When acquiring and analyzing data, it’s often useful to isolate a particular event, or area of interest. When dealing with very large data files, containing days, weeks or even months of data, this may seem like a daunting task. In this application note, we’ll demonstrate the ability in the WinDaq Waveform Browser, using the ‘Time Read More
Stand-alone Data Acquisition and Flash Memory
For years, DATAQ has offered a number of different flash memory solutions for stand-alone data acquisition. Beginning with standard 2GB max capacity SD-style cards for older DI-710/718 series data loggers, progressing to the 32 GB thumb-style USB drives, included with contemporary DI-2000 and DI-4000 series instruments. With maximum sample rates on the order of 14.4 Read More
Convert and Combine WinDaq Files in Microsoft Excel Format
Getting data into Microsoft Excel format is one of the most common customer requests. Often times customers are dealing with numerous data files, and the prospect of manually converting those files, one-by-one, into .CSV format. Fortunately, the software engineering team here at DATAQ has a solution! In conjunction with the WINDH32.EXE (WinDaq Waveform Browser), the Read More
A Meter Display for WinDaq Data Acquisition Software
The question often arises, “Is there a way to display the actual values in WinDaq?”. While real-time numerical data is displayed in WinDaq data acquisition software along with a real-time graph, some customers might prefer to display data in a larger “meter-style” graphical format. Fortunately, there’s a WinDaq add-on that allows you to do just Read More
Measuring Wind Speed Using an Anemometer with a 4-20mA Output and a DI-2108-P Data Logger
One of the most common measurements in data acquisition is that of 4-20mA analog signals. Not only are 0-20mA and 4-20mA process current measurements extremely common in industrial settings, but a significant number of flow, pressure and rate sensors also feature 4-20mA outputs. Why Choose a 4-20mA Output? Additional Reading:4-20 mA Shunt Resistor and Current Read More
Stand-Alone Date/Time Stamps in Microsoft Excel
A critical component of data acquisition, date/time stamps allow you to determine the status of your device under test at a particular instant in time. How that date/time stamp is displayed, and the precision (to the nearest tenth or hundredth of a second) can be quite subjective. Some like to see the date first (mm/dd/yyyy), Read More
Making Pressure Measurements with the DI-1100 Starter Kit
As discussed in a previous post, acquiring pressure data for review and analysis is a common and important data acquisition application. In this application note, we’ll demonstrate the ease with which pressure data can be displayed, archived and analyzed on the cheap using DATAQ Instruments model DI-1100 starter kit, WinDaq data acquisition software and the Read More
How to Determine Power Consumption Using a Current Probe with the DI-4108
In this article, I will show you how to display and record current (Amps) using a DATAQ Instruments model DI-4108-U, WinDaq data acquisition software and a 400 Amp AC/DC current probe (Electronic Specialties Model 697). I’ll use the current information to determine how much energy is used in a typical household appliance. I chose the Read More
New Stand-alone Data Logging Features Added to the WinDaq Dashboard
The latest version of the WinDaq Dashboard includes two helpful new features to the Stand-alone data recording functionality of the DI-2108, DI-2108-P, and DI-4000 Series of data acquisition and data logger products. Record on Power Startup Use the Record on Power Startup checkbox in the Stand Alone Setup window to begin a recording session to Read More
