The DC100 utilizes long RAM memory (1 MB standard, 2 or 4 MB optional) to provide simplified, low cost, low maintenance, data acquisition and recording without needing a PC, hard disk, paper charts or pens.

• "Single memory" - using the entire memory as one data file
  Data acquisition and recording are performed with the entire memory used as a single data file. Simply pressing the START key starts data acquisition and recording until the specified length of data has been recorded.
  
  
  
  
• "Repeat memory" - continuous data saving
  The memory is divided into multiple data files for data acquisition and recording. When the first file becomes full, the next file is selected automatically and used to record data without interruption. There are two ways of dividing the memory.
  
  
  
  
  1. Dividing the entire memory into 2, 4, 8, or 16 files of identical size
     Example: When dividing into four files
     
     
     
     
  2. Dividing the entire memory arbitrarily by specifying the data length of each file
     Example: When making a file of 1 MB
     
     
     
     
• "Rotary memory" - automatically deleting and updating the old file
  When all the divided data files become full, the data file containing the oldest data is automatically updated with new data and data acquisition and recording continue.
