Includes DC and all frequency components up to 3 kHz.
  • Page 156 User Setup The system defaults to Active Power as the output mode. The selection between Pa, P1, and Pt is determined by the user setting on page 2 of the User Preferences menu. The default Kh of the system is 10 micro-units per pulse. Hence the default output is 10 μWh per pulse.
  • Page 157 When operating in Frequency Domain measurement mode (a power computation every 4 cycles), ® the PowerMaster computes the result for a four cycle interval (for example the cycles designated by the vertical cursors above) and outputs the associated pulses starting approximately 10 ms later.
