App for Vibration Testing on iPad: Operating Modes

• Editing: cut, paste, rescale, fill in, taper end points, apply windows, decimate
• Displacement Compensation: brick-wall high pass filter, high pass filter, DC removal, or disabled
• Compensation Template: high pass filter, low pass filter, band pass filter, acceleration DC removal, velocity DC removal.
• Signal View: time waveform of acceleration, velocity, and displacement; FFT spectra; shaker limits; histogram
• Editing Redo: allows the user to redo a previous editing
• Window: half sine, Hann, triangle

General Options

• Line number for spectral analysis sets the number of spectral lines. More lines increase the resolution of frequency data.
• Bin Number sets the resolution of histogram data.
• Profile Quantity sets the quantity as acceleration, velocity, displacement, or voltage
• Undo Max. Step sets the number of cached operations for the Undo command
• Start Average Frame sets the starting frame of the average.

Unique Features for Vibration Testing on iPad

Black Box Mode: Operating Without a PC
A supported vibration test controller can operate in Black Box mode which allows it to perform a test without a connected PC. In this mode, a PC is used only to configure the system before the test and then to download the data after the test is complete.

Languages
English, Japanese, and simplified Chinese are available. The language can be switched through the iPad language environment without reinstalling software.

Auto Test
Auto test can include multiple tests in the test sequence and run sequentially in loops. The sequence can be edited and initiated by the user command.

Vibration Utilities App

Crystal Instruments in partnership with our sister shaker company Sentek Dynamics provides users with the Vibration Utilities mobile app on iOS and Android. This app provides calculation features for sizing your vibration profile (Random, Sine or Shock) and searches through our catalogue of shakers and controllers for the best fit.

Continuous Data Recording

During vibration testing, all measurement input and drive signals can continuously record to a Spider-NAS or the internal storage residing in each front-end. Users can view and analyze data files with Crystal Instruments Post Analyzer. The variable sampling rate can be enabled to simultaneously record slow-change signals together with high speed vibration data.

Spider Vibration Testing

From the EDM App for iOS™, the user can select one of the Spider front-ends detected through its wireless network. The EDM App for iOS™ can be disconnected or reconnected to any valid front-end. The EDM App for iOS™ software can only run one Spider front-end at a time. Each Spider front-end has its own access control password to prevent unauthorized access on the wireless network.

• Spider-81/81B Vibration Test Controller
• Spider-80X/80Xi High Channel Vibration Test Controller - Scale up to 512 Channels
• Spider-80M MIMO Vibration Test Control System
• Spider-80SG General Data Acquisition Device with Strain Measurement

Monitoring Through EDM Cloud

All vibration tests in EDM-VCS support status checks through EDM Cloud. With EDM Cloud support, users can set up any VCS test to upload live data or run logs for completed tests to a cloud storage space provided by Crystal Instruments, where data is securely stored in the user’s account.

The EDM Cloud website is located at https://cloud.go-ci.com. Users can access EDM Cloud from anywhere in the world to check the status of past and current tests. A secure login flow ensures the status can only be checked by authorized personnel with proper credentials. Multiple logins for accessing the same Cloud account is available.
