DR130

The DR130 can perform various computations such as the four arithmetic operations, measurement data integra-tion processing, and detection of maximum and mini-mum values, in realtime. The results of computations are sent together with the measurement data to a PC thus reducing the burden of analysis work and improving the measurement efficiency.

The main computation functions of the DR130 are as follows.

• Standard computation functions:
  Linear scaling, moving average, differential computation
  
  
• Computation options:
  Four arithmetic operations, logic operations, related operations, computation of absolute and relative values, and statistical computations (maximum, minimum, mean, and integrated values)

• Moving average function
  This function renews the measured value while computing the moving average, hence it is effective for monitoring the trend of a varying input signal over a long period. It can also be used as a digital filter when noise components are present on the input signal. You can set the number of moving average scans by selecting a value between 2 and 64.
  
  
• Batch integration
  By using the DR130 in combination with the optional DI/DO module or alarm function, you can easily perform batch processing.
  
  

You can select a floppy disk function as an external memory device. You can save a number of set values and recall them whenever necessary, and in addition store the measurement data before and after an alarm, and also computed results. You can record the memorized data on a chart, or analyze it or make it into a report using a personal computer and commercially available spreadsheet software.

• If the floppy disk drive function is selected, the measurement data is stored in a binary format in the 512 kB (SRAM) internal buffer memory. You can also copy measurement data from the internal buffer memory to a floppy disk while converting it into the ASCII format.
• By combining the memory function with a remote function, timer, key operation, etc., you can memorize data at fixed intervals (e.g. 1 hour), or save the results of statistical computations alone (integrated value or maximum and minimum values).
• The DR130 comes with standard data conversion software, enabling you to convert data into the ASCII, Excel, or Lotus 1-2-3 format.
