Now that you know something about the DAQSTATION, you're probably wondering how it can be used in your applications. A number of sample applications are presented below to give you some ideas. |
With an emphasis on "continuous"
The ability to record continuously is important when:
|
|
- You have a factory that's running 24 hours a day and want to be able to monitor and record data constantly.
- You want to keep records of the water level of a dam in a remote location, but you can't get out to the location on a regular basis.
What do you do? Well, in such cases, you can save your measurements in AUTO mode using large capacity storage media such as ATA flash memory cards or Zip disks. Insert the media in the drive on the DX Series. Now simply press the start button and you're ready for extended, continuous measurement recording. There's no need to worry about running out of ink or changing recording paper as in the case of conventional paper recorders.
The DX106 (6-channel model, no calculations, display updating interval of 30 minutes per div (data saved every 60 seconds)), together with a 20 MB flash memory card, will actually let you record data in a display data file continuously for a year or longer.

The ability to record just the data you need is important when:
|
- You only need the data recorded between the time you arrive at a site in the morning and when you leave in the evening.
- You want to collect experimental data through a simple procedure (just starting and stopping the recording process).
The DX Series recording Start and Stop buttons let you record just the data you need. For data recorded over extended periods of time, an ATA flash memory card or Zip disk can be used to save data in AUTO mode. Each time the recording process is stopped, a new file is saved on the storage media. If you don't require recording over extended periods of time, you can save data to a floppy disk in MANUAL mode for easy analysis.

|
The ability to capture abnormal data is important when:
|
- You want to detect and record data under abnormal conditions for detailed analysis on a PC.
The DX Series' trigger functions and event file capabilities are useful for this purpose. The trigger functions are easy to use once you specify a trigger source and data length (sample time). For example, by setting alarms as the trigger source and setting the data length (sample time) to ten minutes, you can create a 10-minute event file each time an alarm occurs. The DX Series also has pre-trigger functions that let you record and analyze data preceding a trigger.

The ability to record extended-period data and detailed data at the same time is important when:
|
- You want to continuously record the temperature of turbine bearings 24 hours a day, while simultaneously making a detailed analysis twice a day of just the measurements obtained at turbine startup and shutdown.
The combination of display data files and event files eliminates the need for two separate recorders. Do your continuous recording on display data files, and record the measurements obtained at turbine startup and shutdown in event files based on triggers. (See below illustration)

|
For measurements related to food and drugs applications The ability to use batch file recording is important when:
|
- You want to record a batch process, including batch numbers and comments with each batch file.
The optional batch function lets you add batch numbers (text strings as long as 16 characters, followed by four-digit serial numbers) and comments (text strings as long as three lines of 32 characters each) to each batch file. This information can be viewed when you open the data files on a PC.
|
|
The ability to create reports automatically is important when:
|
- You need daily and monthly reports based on acquired data, but don't want to go through the hassle of reading the data from the recording paper and preparing the reports manually.
The optional calculation function enables DX Series to produce reports automatically based on the measured data. The DX Series can create reports in hourly, daily, weekly, daily+weekly and daily+monthly formats. Average values, maximum values, and minimum values for fixed time intervals, as well as cumulative values are calculated and recorded in reports. Report data created and saved with a DX Series can be opened and worked with on a PC using DAQStation software. This greatly improves reporting efficiency.
