  • Page 102 PPA55xx Quick User Guide Setting up PPA for “internal” measurements. The set up procedure for internal measurements is very similar to that above for external measurements. The only difference is in the configuration of the Ranging settings. Ranging should be set up as follows: Press “RANGE”...
  • Page 103 PPA55xx Quick User Guide Connecting up the PPA for “internal” measurements. The breakout box is connected to a mains supply. A load is connected to the breakout box to produce a current for the PPA to monitor. The PPA is used to monitor the voltage and current on the connections of the breakout box.

  • Page 107 PPA55xx Quick User Guide Harmonic Analyzer Mode Harmonic verification Verify that Vthd is nominally the same across all phases inputs, as a reference signal (such as a squared wave) is not being used we cannot verify individual harmonic magnitudes. This is not a problem as we have already verified this with the external inputs Page 104...
