  • Page 32: Digital Filtering Operation

    Chapter 3 Unit Configuration Digital Filtering Operation Digital filtering smooths out the display of fluctuating values. The parameter FILTER S defines the operating range of the filter. This operating range is represented as a yellow band (each small square is one digit). While the measured value (red curve in Figure 23) is within this band, the filter is active.
  • Page 33 Unit Configuration Chapter 3 The FILTER S parameter, which represents the action range of the digital filter, is programmed to a value that must be slightly higher than the percentage amplitude of the fluctuation, for example, 1.0%. FILTER CO: if the new value that is measured by the instrument is within the action range of the filter, the new displayed value is obtained by adding algebraically the previous value to the variation divided by the filtering coefficient.
  • Page 34 Chapter 3 Unit Configuration FILTER CO: if the new value that is acquired by the unit is within the filtering action range, the new displayed value is obtained by adding algebraically the previous value to the variation divided by the filtering coefficient. As a consequence, a value higher than this coefficient implies a higher settling time and therefore better stability.

In addition, Modbus TCP/IP is supported in units that are ordered with optional Ethernet communication. Communication parameters in the power monitor must be configured. See the Unit Configuration section of this manual.
  • Page 44 To avoid errors due to signal reflections or line coupling, a termination resistor must be connected at the RS-485 ports of the master station and of the furthest power monitor from the master station. In the PowerMonitor 500, you can implement a jumper between (B+) and (T) to apply the required termination resistance between (A-) and (B+) internally.
