If the COVID-19 pandemic has proven anything, it is that we live in a business climate where efficiency and accuracy have never been more important. In other words, none of us can afford to make costly mistakes. With that in mind, I’d like to share some tips for…
Precision testing generates precision data. Acquiring, accessing, and analyzing these data files allows engineers and scientists to lower product costs, engineer time-saving solutions, and even save lives. National Instruments (NI) created the Technical Data Management Streaming (TDMS) file format for high performance data streaming and retrieval. This binary…
Our test engineers collect vibration data on rotating machinery using four basic tools. We use a Laptop computer with iTestSystem software to stream accelerometer and rotational/speed pulse sensor data from a National Instruments cDAQ equipped with vibration and voltage input modules. The video above shows how to collect…
On a recent project, one of our engineers needed to measure structural strain at several locations on mobile lifting equipment while in operation. Since the strain measurements were distributed and mobile, a wireless internet of things (IOT) solution was required. This blog describes the steps and tools we…
Our iTestSystem customers who routinely acquire data with high channel counts and data from full-bridge transducers recently requested that we update the sensor auto-zero utility to improve test setup efficiency. In the latest version of iTestSystem, we updated the sensor auto-zero utility to include all channels that use…
In order to prevent or troubleshoot structural vibration problems, it is important to characterize a structure’s dynamic behavior using both experimental and Finite Element Analysis (FEA) technologies. One method used to identify a structure’s vibration modes is to perform a roving accelerometer or roving hammer impact test. In…
While iTestSystem is designed to collect data from specific sensor types like strain, voltage, current, and accel; custom signal types such as pressure, displacement, and force can also be configured by utilizing the Custom Scale functionality during the channel creation process. For example, manufacturers often need to measure…
As engineering consultants, it’s the nature of our business for our work to take us out on the open road. It is for this reason that we are proud to support several state Departments of Transportation (DOT) with their structural testing and data acquisition needs. We travel the…
As the global market moves steadily in the direction of increased productivity through integration of software into the world of testing services, Integrated Test & Measurement finds itself at the forefront of the field. Our other LabVIEW developers and I have been hard at work creating custom applications…
Over the past few weeks we have been updating our Joint Time Frequency Analysis (JTFA) tool for iTestSystem. In general, the JTFA tool is used to show how the frequency content of a signal changes over time. This tool is particularly useful for analyzing and visualizing vibration and…
When we develop LabVIEW™ applications for our customers, a common request is for a simple, resizable and intuitive user interface (UI) for data visualization. In these cases, we use a tree control and a subpanel. This type of UI functions like a tab control that automatically resizes. The…
The latest video in the ITM Live Demo series shows users how to configure an Ethernet/Network cDAQ or FieldDAQ chassis with NI Measurement & Automation Explorer (NI Max). One of the most common questions we get from iTestSystem users; How do I configure my network/ethernet cDAQ or FieldDAQ…
