Page 6: Operation
Operation WARNING: Do not connector or disconnect the 25 pin external micro d‐sub connector while the 4401 is powered. This may result in damage to the unit and/or loss of data. 1. After the computer is restarted, the user will find the “9009 VibraCorder” icon in the Windows menu, as shown in Figure below. A Shortcut will also be created on the Desktop for ease of access. Figure 4: VibraCorder Icon. 2. Insert the SD card into your PC and launch the software. Figure 5: 9009 Software 3. Create configuration file – this tab allows the creation of the configuration file for the data acquisition. Rev A, ECN 12775 Page | 6 ... - Page 7 3.1 It is recommended to format your SD card before every use. Use SD card drive navigation window to select the card and press “Format SD card” button. 3.2 Free run is determined by switch on hardware on. Default value of 40 pre‐triggered samples is provided. 3.3 Three different sampling rates are available. The measurements bandwidth is effectively half of the selected sampling rate. These rates are 250, 1200, and 4280 Hz. 3.3 “Keep running after triggering” check box will allow for continuous recording once the triggered value is reached (Triggered acquisition has to be selected for this feature). 3.6 After the popup “Config.txt created” appear, press “Ok” button and safely eject the SD from the slot Insert the Micro SD card into the 4401AX Micro SD card slot and press the “Power” button. Ensure Vibracorder is powered off before inserting or removing Micro SD Card. If SD Card is removed during any operation, a format of the card in a PC may be required as the card file system can become corrupted. 4. The firmware of the VibraCorder will verify the Micro SD card operation. The green “Ready Indicator” LED will remain illuminated if the system passes built in self tests and SD card is present. Dytran Instruments, Inc. specifies using only the included Sandisk Extreme Plus 32GB ‐ SDSQXVF‐032G‐ GN6MA. Other cards may operate, but have not been tested and are not guaranteed to work with the system. 4.1 After the accelerometer is verified operational, the firmware will check for the presence of the configuration file. Three beeps prior to startup sound will indicate the configuration file is not found.

When selected new, all the previously displayed data shall be erased and substituted with newly imported data set. 7.2 “RELOAD SELECTED DATA” button shall reload the original set of data into the analysis window. 7.3 “LOW PASS FILTER” and “HIGH PASS FILTER” buttons shall apply specified filter to the data, user shall be prompted for corner frequency and filter order. Butterworth topology is used. 7.4 “SINGLE INTEGRATION” and “DOUBLE INTEGRATION” buttons will apply either single or double numerical integration. The software shall automatically apply a high pass filter before performing integration (to avoid any data run off). User shall be prompted for corner frequency of the filter. 7.5 “OVERSAMPLING” button shall perform non‐linear interpolation on the data set, calculating additional data point in between the existing one. The user will be prompted for the oversampling frequency: Figure 7: Same data set before and after oversampling with 32,000Hz frequency Rev A, ECN 12775 Page | 9 ...

“RPM” control requires user input for TSA calculations and cursor location. “PLOT HORIZONTAL UNITS” allows the change between Hertz, Orders, and RPM for FFT graph. 7.10 “GET RMS” button shall show the RMS signal value for each axis. 8. “DATA EXPORT” tab allows the export of the data to conventional file formats: .csv, .mat, .tdms, .uff, and .sqlite User shall define the location of the file on the PC using the explorer. If “EXPORT ALL RAW DATA” is checked, the software will export all the raw data from the measurements file. If the “EXPORT ALL RAW DATA” is not checked, the software will export only the content of the analysis screen. Note: If running from external power through the 25 pin micro D‐sub external connector, the Vibracorder should be powered on and off via an external power supply. Please ensure that external power is off when performing any connection or disconnection to D‐sub connector. Turning the Vibracorder on with tactile buttons (battery powered operation) will not allow remote power cycling of the Vibracorder. VII. Mechanical configuration and mounting 1. Refer to 127‐4401A2 outline drawing for physical dimensions of the device. 2. Model 4401AX must be mounted using the supplied removable mounting plate and screws. Select a desired hole pattern as outlined on 127‐4401A2 drawing (2.00” x 2.00”, 2.00”x 1.00” or 1.00”x1.00”), drill and tap four 10‐32 holes x 0.35” minimum depth. Mount the plate to the test surface using the supplied four 10‐32 low profile head screws as shown in Figure 9. Torque screws to 28 lb‐in. Figure 9 Rev A, ECN 12775 Page | 11 ... -
Page 12: Data Recording Considerations
Mount model 4401AX onto mounting plate as shown in Figure 10. Secure the unit to the mounting plate from both sides using the four 4‐40 button cap screws supplied. Torque screws to 8 lb‐in. Figure 10 VIII. Data recording considerations The Vibracorder is powered by a non‐replaceable lithium ion battery. The minimum continuous recording time is defined as 24 hours. During freerun, the recording will be automatically broken down to 4gb files. That means if the recorder is left in free run, it will record the into VR‐00001.BIN, then it will close VR‐00001.BIN, open new file VR‐00002.BIN and continue the recording. It will perform that operation until battery runs out. Rev A, ECN 12775 Page | 12 ... -
