The software upgrades are secured from being uploaded to other hardware versions, than they are originally destined to.

• Fixed incorrect scaling of recorded waveforms of Unpe voltage and In current in 1-phase and split-phase networks.
  
• Average values of power factor and tangent(phi) are now calculated from average power values.
  
• Average value of reactive power (nonactive power) in 3-wire networks is now calculated from average apparent and active power.
  
• Removed harmonics smoothing.
  
• PC disconnect time when communication is lost has been shortened from 5 mins to 30 seconds.
  
• Added support for PQM-701Z.

PQM-701_FW105HW 

• Fixed: logging not started in event threshold trigger mode.
  
• Fixed: recording of the first erroneous Plt flicker result.
  
• Added: displaying E150 error message when internal power supply is not working (when fuse is open or not inserted).
  
• Added: possibility to measure THD up to 40th or 50th harmonic (Sonel Analysis 1.0.43 or newer required).
  
• Updated: wireless transmision (OR-1 version 1.03 or newer required).
  
• Added: signalization work of analyzer when the display is off.
  

PQM-701_FW104HW

• Fixed: keyboard lock setting can be now changed while logging.
  
• Fixed: faster switching to the internal PLL clock after L1 voltage interruption.
  
• Fixed: bug with a possibility to clip first two periods of voltage and current event waveforms recordings.
  
• Fixed: bug with writing additional aggregation record for averaging periods 10s and longer.
  
• Added: keyboard lock is now rearming 30s after unlocking (if not pressing any keys).
  
• Added: SDHC card support.
  
• Faster SD card initialization.
