The main unit of the DA100 with optional MATH feature can perform the four arithmetic operations, integration of measured data, and computations such as detection of maximum and minimum values, in realtime. Even without the optional feature, the DA100 can compute linear scaling, difference and moving average. The results of such computations are transferred with the measured data to a PC, thus reducing the system requirements on the PC and also resulting in more efficient analytical processing. The number of computing channels with the MATH option is 30 for the stand-alone model, and 60 for the expandable model.
The main computing functions are as follows (the shortest computation period differs depending upon the kind of computation).

• Standard computing functions:
  Linear scaling, moving average, differential calculation, pulse integration (when a pulse input module is recognized).
• Optional functions:
  The four arithmetic operations, logic operations, related operations, calculation of absolute and relative values, and statistical calculations (maximum, minimum, mean, and integrated values for fixed intervals)

By using the DA100 in combination with the optional DI/DO module or alarm function, you can easily perform batch processing.

This function renews the measured value while calculating the moving average, effectively monitoring the trend of a varying input signal over a long period. It is also usable 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.
