5.3 Calculation and display of measurements

This chapter deals with capture, calculation, and display of all supported measurement quantities. For
more information about display presentation see chapter 3.2. Only the most important equations are
described; however, all of them are shown in chapter APPENDIX C: EQUATIONS with additional
descriptions and explanations.
5.3.1 Voltage
Voltage related measurements are listed below:

5.3.2 Current
Real effective (RMS) value of current.
Figure 51: Current equation
All current measurements are available on communication as well as LCD display.
5.3.3 Active, reactive and apparent power
Active power is calculated from instantaneous phase voltages and currents. All measurements are
seen on communication or are displayed on LCD. For more detailed information about calculation see
chapter APPENDIX C: EQUATIONS.
