Product: eZ-Analyst Software, v 5.0.104
CD: Data Acquisition, p/n 1022-0601, Rev 6.4
The following two enhancements have been added to eZ-Analyst software: (1) A Measurement Mode panel with a checkbox has been added to the Preferences Tab. (2) The Low Frequency Cutoff panel has been modified in the FFT Setup tab.
1. A Measurement Mode panel with a checkbox has been added to the
Preferences Tab. See following figure. This feature, when enabled
(checked) reduces the chances of accidentally overwriting your existing
Hardware and Configuration Setup file.
Edit > Configuration > Preferences Tab
Measurement Mode
In eZ-Analyst the same Hardware and Configuration Setups [that are used to Record data to disk in Measurement Mode] are also later used to read and analyze recorded data in Playback Mode.
After data has been recorded to disk, subsequent critical Configuration changes (such as changing the number or selection of enabled channels, or changing the Analyzer analysis frequency or nyquist settings), if saved to disk, would prevent eZ-Analyst from correctly interpreting data that was previously recorded using that Setup. Reversing the changes made to the Hardware Setup could restore the ability to view the previously recorded data, but only if ALL of the changes were returned to their original settings.
The Measurement Mode preferences checkbox helps reduce the chance of accidentally overwriting your existing Hardware and Configuration Setup file. The checkbox setting determines whether or not you will be prompted to save-to-disk the current Measurement Mode Setup when the program is either (a) closed while in Measurement Mode, or (b) the selection is made to switch from Measurement to Playback Mode.
Unchecked - If the checkbox is unchecked, you will not be asked to save the Hardware Setup, nor will the Measurement Mode Hardware Setup (along with any changes made to it) be saved to disk when the program is closed, or the mode switch is made. If you are switching from Measurement to Playback Mode, the Configuration Setup is restored by reading the Setup from the disk. Checked - If the checkbox is checked, and the program is either closed while in Measurement Mode, or the selection is made to switch from Measurement to Playback Mode, you will be asked if you want to save the Measurement Mode Hardware and Configuration Setup to disk.
You can respond to the prompt by clicking: Yes, No, or Cancel, with the following results:
o Yes - displays the Save Analyzer Setup File dialog, allowing you to select an existing setup file to overwrite, or enter a new filename to
create a copy of the existing configuration.
o No - accepts the current action without saving the Hardware and
Configuration Setup to disk.
o Cancel - aborts the switching of Mode or the program shutdown.
From the Save Analyzer Setup File window, if you press Cancel, you will abort the Mode switch operation, or abort the program shutdown.
However, if you press Save, one of three things will happen:
(a)If you entered a new filename [that does not already exist] the Hardware
and Configuration Setup will be saved to disk, along with a Plot Setup file that represents the current number and layout of display windows. In
addition, the switching of Modes [or program shutdown] proceeds.
(b)If you entered or selected a pre-existing filename and the Hardware and
Configuration Setup file already exists [but there is no recorded data
present with the same name] you will be asked if you want to overwrite
the existing Setup file.
If you choose Yes, the file will be overwritten and the shutdown [or the
switching of the mode] will proceed. If you choose No, you will be
returned to the Save Analyzer Setup File dialog box where you can
either Cancel the operation or choose a different file name.
(c)If you entered or selected a pre-existing filename and the Hardware and
Configuration Setup file already exists [and there is previously recorded data file present with the same name] you will be warned.
The warning states that there is a possibility that overwriting the
Configuration file may result in the inability to read the previously acquired data. The warning dialog asks, “Do you want to Overwrite the existing Hardware Configuration file and possibly make the existing data
unreadable?”
Yes - If you choose Yes, the file will be overwritten and the shutdown or switching of the mode will proceed.
No - If you choose No, you will be returned to the Save Analyzer Setup File dialog box where you can either Cancel the operation or choose
a different file name.
2. The Low Frequency Cutoff panel has been modified in the FFT Setup
tab. The FFT Setup tab previously offered an option to select either "Skip Data" or “Zero Data” in regard to Low Frequency Cutoff. Now, “Zero Data” is the method used. The following figure shows the modified panel.
The Low Frequency Cutoff panel can be used to change frequency-based displays.
Example:
If you wanted to remove frequencies below 10 Hz, you would enter "10" in the numeric field. In the Function View display window, all frequencies below 10 Hz would be set to a value of zero.
Entering a value of "0" in the numeric field disables Low Frequency Cutoff.
This means all frequencies will be displayed.

Product: eZ-TOMAS Software, v 5.4.24
CD: Data Acquisition, p/n 1022-0601, Rev 6.4 The following enhancements have been added to eZ-TOMAS software.
1. Multiple Rows of Gauges.
Up to 32 gauges are supported on the main window. Use the Gauge menu to select the gauge format. 8, 16, 24, and 32 Gauges are available. For
systems with more than 32 Channels, use the page up and page down keys to scroll through the gauges.
Gauge axis caption shows spectral band name, units, and scale.
Current gauge values are shown on Gauge Axis.
High Water (peak hold) values and dates are shown using Mouse Over
popup.
2. Multiple Machine States Supported
RPM and Time can be used to define a Machine State. Six (6) states are supported. State 0 (“All Other”) is defined as a default state.
A machine state is defined by RPM Range and Time within that Range.
For example, a machine state could be defined as 60 minutes after machine speed has reached 3600 RPM.
Unique Limit Sets can be defined for each Machine State.
3. Statistical Report Generates Limits for Machine States.
The statistical report can be used to generate limits for each machine state.
The user can select channel(s), spectral band(s), and variance for high and low limit(s).
4. Change Cursor Color within Plot Displays
The cursor color can be changed within the plot displays. Right Click within the plot area and select the Color Preferences menu.
5. Apply DC Coupling Button for Time Waveform.
For Time Waveform displays, you can apply the DC Coupling offset to the plotted data. This can be useful for Displacement Probes.
6. “g – ips – mils” Units Convention for A-V-D Probe Types.
Acceleration – Velocity – Displacement units are selected in the Acquisition Tab. Improves label consistency.
Acknowledgement
7. Alarm
If an Alarm event occurs, Channel Labels will flash until the alarm event is acknowledged. Click on the OK button in the Limit check frame to
acknowledge all outstanding alarm events. Right click on a channel gauge to acknowledge alarm events for an individual channel.
Channel Alarm Reports.
8. Individual
To list alarm events for a specific Channel, Right Click on the Channel
Gauge and select the View Alarm Event(s) menu option.
9. PlotSet File PopUp Menu
The left most button on the 2nd toolbar, activates a popup menu that lists the saved plot setup files in the current eZ-TOMAS directory. Allows you to
quickly recall plot setup formats.
10. Analysis Displays - Spectral Band Color
The spectral band color trace can be changed within Plot displays. Right Click on Spectral Bands and select the popup Color menu.
11. Analysis Displays – Waterfall Cursor Track
A cursor track is attached to the waterfall cursor. If machine speed is
known, the track is based on the current multiple of machine speed. (Order) The cursor can be moved and the track will correspond to the order on each spectrum traces.
12. Post Process – Overlap Processing.
Overlap processing can be used to analyze machine transients using
continuous data in the FIFO history file. Select the Overlap Processing
button to calculate and store data.
Select the overlay Overlap data button to plot the overlap processed data on Bode and Polar analysis displays. Feature can be used to compare various startup and shutdown data.
13. Production Test Reporting
User Interface enhancements have been made in the Production Test feature. Acquisition and Report limit set points are consistent for all machine states, including delayed states.
14. AutoBackup Uses Rename Based on Date / Time.
If Automatic Backup is selected, prior to the FIFO event, eZ-TOMAS will
rename the existing data project to “project name” followed by “_DateTime”.
For typical XP computers, the backup process will take less than 3 seconds.
After the backup process is completed, new data is stored in the original
project file.
All Backup data files have the Read-Only file attribute set.
15. Selectable User Fonts in Display Preferences
Font style and size can be specified using display preferences.
16. User Defined Function Keys
Function Keys F1 through F12 can be programmed. Options include turning On and Off Acquisition, Limit Checking, and Digital IO. A Function Key can be programmed to open a specific eZ-TOMAS Project.
17. Bode Display – Invert X Axis.
An option to Invert (Flip) the X axis scale for shutdown events is available in Display Preferences. When selected, and displaying historical shutdown data, the RPM scale will be from MAX to MIN.
Product: Daq Device Verification Procedure, rev 1.3 CD: Data Acquisition, p/n 1022-0601, rev 6.4
Partial View of an Excel Spreadsheet used for Verification of Specs
A verification procedure can be used to determine how well a device is meeting its specifications and to show you how your device has changed over time. You can use this information to determine meaningful calibration intervals for your specific application.
A Daq Device Verification Procedure has been added to the <View Manuals> feature of the Data Acquisition CD, first available on CD version 6.4. The document contains information about verifying acquisition data for IOtech Daq devices, i.e., DaqBooks, DaqBoards, and Personal
Daq/3000 Series devices.
We use two programs in our verification process. First we use DaqView to obtain a “measured value.” We get this number from DaqView’s Scope Status Bar. Next, we enter this value into an Excel template. Equations within the template automatically determine if the deviation [between measured and applied values] is within tolerance, per published specification.
The Excel spreadsheets can be found in the CD’s root directory; simply navigate to the CD’s Misc (Miscellaneous) folder, open it, then open the Cal (Calibration) folder within. The procedure includes a table which indicates which Excel spreadsheet is to be used for a given device verification.
Upon completion of the verification you can save a copy of the Excel sheet for your electronic records and print copies for hardcopy reports.
