iTestSystem Application: MultiDAQ

iTestSystem MultiDAQ

MultiDAQ is a configurable general data logging and real-time data viewing application for iTestSystem (iTS).  An intuitive user interface allows test technicians and engineers to choose sensor channels, synchronize DAQ hardware,  change sample rates,  setup input data filters, configure data file triggering, and manage automated data file naming.  Once configured, MultiDAQ provides graphical, tabular, and digital real-time data views for test operators to visualize data trends during the data collection process.

Function List

  • Stream data from multiple C-series NI chassis.
  • Stream data at different sample rates.
  • View real-time data, including RMS and waveform data in tables, graphs, colormaps, spectra, and waterfall graphs.
  • Alarm when signals exceed channel’s minimum or maximum values.
  • Trigger acquisitions based on custom duration or value trigger statements.

iTestSystem Tip: Start and Stop Tests with MultiDAQ Trigger

When deploying a DAQ system for unattended testing, use the MultiDAQ trigger function in iTestSystem to automate data collection.  Data collection starts when the start trigger condition is met.  Data collection stops when the stop trigger condition is met.
Follow the steps below to enable and configure triggering.
  1. Enable auto save
  2. Enable triggering
  3. Build a start trigger statement
  4. Build a stop trigger statement
  5. Start configured MultiDAQ
  6. Let MultiDAQ simplify your data logging..

Webinar Video: ITM Shares MultiDAQ Configuration Tips

Our second monthly Webinar at ITM focused specifically on how to configure the MultiDAQ plugin for our iTestSystem software. Two of our engineers — Chase Petzinger, a software developer, and Todd Holtkamp, a field test engineer, hosted the free online demo on Oct. 2, 2014, to walk users through exactly how to configure ITM’s custom product when using National Instruments MAX hardware.

As you can see in the archived video, they also covered how to create a MultiDAQ session, how to create a task, how to enable synchronization, how to select specific hardware and channels to record data and, finally, they gave some tips for setting up file settings. As usual, we finished off the Webinar by allowing those who joined the GOTO Meeting session to pose specific questions.

Stay tuned for news of our next Webinar so you can join us live.
