Job Editor

Use the Job Editor to create a new job or to modify the configuration settings of an existing job. The Job Editor opens when you select the New Job icon or the Edit Job icon from the Data Logger Schedule tab toolbar.

The Job Editor provides a series of tabs to configure channel, acquisition, logging, and alarm settings, and view data acquired for the job. You can advance through the tabs sequentially using the Next button. Tap the Finish button on any tab to save the settings in the job and close the Job Editor.

Each saved job appears in the job list on the Data Logger window. You can use the Schedule tab toolbar to duplicate jobs, save job settings to a file, and import job settings from one job to another.

The job name is set by default to Job1. You can enter a new name in the Job Name field.

Channels

Use the Channels tab to view the channels included in the job, add or remove channels, and customize channel properties. The channels list includes the name and type of each channel added to the job.

Channels Tab Toolbar
AddDisplays the channel types you can add to add to the acquisition. When you select the channel type, a Selected Channel(s) dialog box opens for you to choose the channel number. A channel can only be added once. Click OK to add it to the channel list and display its properties. Refer to Channel Properties below for the specific options you can customize for each channel type.
RemoveRemoves the selected channel from the channel list. Note that any channel configured as a trigger source or alarm source cannot be removed until the trigger or alarm is deleted or its source is changed to another channel.
ImportImports the channel list from another job in the job list. Tap the down arrow to select the job list to import from. The Import option is only enabled when the channels list is empty (does not contain any channels).
Move Up
Move Down
Moves the selected channel up or down in the channel list. The order of the channel list sets the order of items in the display and in data when it is exported.

Source Select the digital bit to trigger (start/stop) the job.
TypeRising Edge: Start or stop on the digital edge of a rising pulse.
Falling Edge: Start or stop on the digital edge of a falling pulse.
Low: Start or stop when the external digital trigger is 0V (logic low or 0).
High: Start or stop when the external digital trigger is 5V (logic high or 1).
Analog Trigger
SourceSelect the analog input to trigger (start/stop) the job.
TypeAbove: Start or stop when the reading at the selected Source channel goes above the Threshold.
Below: Start or stop when the reading at the selected Source channel goes below the Threshold.
Inside Window: Start or stop when the reading at the selected Source channel is above the Low Threshold and below the High Threshold.
Outside Window: Start or stop when the reading at the selected Source channel is below the Low Threshold or above the High Threshold.
Slope Positive: Start or stop when the reading at the selected Source channel transitions from below the Low Threshold to above the High Threshold.
Slope Negative: Start or stop when the reading at the selected Source channel transitions from above the High Threshold to below the Low Threshold.

Window Types

NoneRecommended for use when your signal content contains random (white) noise or closely spaced sine waves.
Hann Bell-shaped cosine window typically used to analyze continuous signals. Recommended for use when your signal content contains sine waves, a combination of sine waves, vibration data consisting of narrow band random signals, or unknown content.
HammingBell-shaped cosine window optimized to minimize the maximum (nearest) side lobe. Recommended for use when your signal content consists of closely spaced sine waves.
Blackman-HarrisSimilar to a Hann window, this window has slightly wider main lobe but much better dynamic signal range. It is optimized to provide the minimum side lobe level.
BlackmanSimilar to the Hann and Hamming windows, this window has slightly wider central lobes and less sideband leakage.
Flat topOptimized for measuring peak amplitudes of discrete spectral components that are separated by several spectral lines. Recommended for use when your signal consist of sine waves and amplitude accuracy is important.
Logging

Use the Logging tab to configure data logging and to set logging options. Acquired data is logged to a binary WebDAQ data *.wdd file. You can save logged data to the internal storage on the device, or to an external SD card or USB storage device.

Acquiring data at higher speeds can generate large file sizes. If the log file exceeds the capacity of the selected storage location, a "File too large" error is returned and the acquisition stops. Internal WebDAQ storage can hold up to 3 GB of data. When acquiring larger data files, use external media. If you expect to acquire a large amount of data to a single file when logging to external media, do not use media formatted with the FAT32 file system as the max file size is limited to 4 GB. If the log file on FAT32 media grows beyond that size, a "File too large" error is returned and the acquisition stops. Before starting a logging session of this type, reformat the media using a different file system such as NTFS. Refer to the Frequently Asked Questions (FAQs) topic for more information about file systems.

Job Editor Logging tab

Logging Tab
Log File OptionsSpecify where to save data and whether to append or overwrite data:
  • Log File Name: The location and name of the data file. Tap Browse to enter a filename and specify where to save the file — choose from Internal Storage, SD Card, or USB Storage Device. Icons are provided to create subfolders, refresh the file list, and navigate the folder hierarchy. External media must be inserted for the external options to display.
    Logged data is saved by default to the device internal memory as Job1.wdd.
  • Append Date/Time to File name: Appends the date and time to the filename. Enabled by default. Disable to overwrite the data file upon each run of the job.
  • Notes: Optional information about the job that displays in the file header of the data file.

Use the Alarms tab to add an alarm, set alarm conditions, and specify the action(s) to take when an alarm is triggered, such as send a text notification, set the status of a digital bit, or run a specific job.

By default, alarm data is saved to a *.txt file in a location you specify — internal storage on the device, SD card, or USB storage device. Each alarm written to the specified file is appended, including repeated runs of the job.

When initially opened, the Alarm tab only displays a New  tab. Tap to add an "Alarm #" tab with alarm options to configure.

  • Email or SMS Message: Sends a notification that an alarm occurred via email. Specify the SMTP server from those you set up on the Email/SMS tab. For email notification, add one or more email addresses (separated by semicolons). For text, add one or more phone numbers and the associated SMSGateway. Click the 'Retry On Error' option if you want the WebDAQ to keep trying in the event of a connection error. Note: Email and SMS Message cannot be enabled at the same time. For more information about notification options, refer to Email/SMS discussion in of the Device topic.
  • Jump to Job: Ends the current job, and starts the specified job when an alarm condition is detected.
  • Digital Output: Sets a digital bit high or low when an alarm condition is detected.
