DATA ACQUISITION SOFTWARE Time Is Precious Structural Strain Measurements When your new product introduction date is set in stone and you aren’t finished testing, you can’t afford to waste time with tedious programming tasks. DAC Express is fast to set up because it requires no programming. Connected hardware is auto-identified and ready for assignment to measurements. Stress and fatigue testing of large structures has special requirements.

DATA ACQUISITION SOFTWARE Set Up Channels With Table/Menu Pull-Downs Simply click on the tabs at the bottom of the screen to display the available measurement channels (shown below). This example screen shows three high-speed inputs connected to accelerometers and two connected to microphones. Select transducers from the pull-down menus shown in the highlighted window.

DATA ACQUISITION SOFTWARE Events DAC Express 3.5 and the EX1200 series allow you to select from a flexible set of alarm conditions so you can be notified when critical test data exceeds its limits. If the data sample exceeds or falls below the level you specified, DAC Express signals an alarm event to occur. For example, you can trigger an alarm event when an input or combination of inputs exceeds specified temperature limits.

DATA ACQUISITION SOFTWARE Select Measurement Rates Once you’ve created the channel connections, you set the sample rates in the timebase screen (not shown). The channel measurement rate for high-speed digitizer channels can be set independently from that of the scanning A/D channels. You can also set the length of the test and the triggering conditions before starting the test. Just Press “Record” It’s as simple as that.

DATA ACQUISITION SOFTWARE With the EX1629 transducer, bridge type can be set on a per channel basis. Excitation and unstrained voltage can be quickly measured before data collection and is stored as part of the advanced settings. All test setup information is automatically saved as part of each project. DAC Express allows you to choose the display type that best fits your needs — whether you want current values, short-term variations, or trend lines.

DATA ACQUISITION SOFTWARE Easily View Multiple Display Types In the hair dryer test example shown below, high-speed vibration and noise data is collected and monitored as time records and frequency spectrums. The strip chart simultaneously displays temperature. Temperature is also displayed in the numeric readout with an alarm set to 70 degrees C. Plus or minus alarms are available on meter and bar graph displays as well.

DATA ACQUISITION SOFTWARE The display wizard makes fast work of setting up multiple graphs and meter displays. Select your channels and display type and the display wizard does the rest. See All The Data On A Channel The data browser allows you select a specific channel for closer review. Simply right-click on the scrollbar display, select the desired channel, and the entire data stream collected for that channel will be displayed in the browser.

DATA ACQUISITION SOFTWARE All or part of the recorded data can be quickly exported in formats compatible with popular analysis and reporting software. To give you a complete overview of your test, the data browser trace at the bottom of the data viewer screen compresses the data view up to 1000 times. Any channel can be displayed in the data browser. DAC Express Release 3.
