FLI-3 and FLI-6

Flicker meter and calibrating generator
 


FLI-3 and FLI-6
To identify a flicker source 3 or more channels are essential. 
That is what FLI-3 or FLI-6 provides. 
 
  • it complies with IEC 555, IEC 868-0 and EN 50160
  • flicker measurement on 3 or 6 channels simultaneously
  • 3 or 6 isolated inputs
  • serial port to communicate with the computer where the measured data will be stored
  • input range: 80-400Vrms
  • 1 minute Pst is continuously displayed (3 or 6 channels)
  • 1, 5, 10, 15 minute Pst is stored
  • logarithmic classifier
  • Pst range from 0.1 to 99
  • visualisation of input time functions
  • automatic restart following voltage outage
  • automatic saving by 15 minutes
  • measuring interval normally 1 month (option up to 1 year)
  • built in calibration generator 
  • menu selectable automatic calibration
  • printed calibration protocol according to IEC 868-0
  • automatic testing of the flicker filter characteristic with sinusoidal or square wave modulation (modulation depth can be set to a proper Pst value eg.Pst=1).
  • accuracy of calibration: dfm=0,001 Hz; dV/V=0.01%
  • accuracy of measurement: better than 5% (IEC requirement) 
  • 2 hour Plt (default), X hour Plt can be set when evaluating
  • evaluation of Pstmax, 2nd, 3rd max, mean value standard deviation, 99% 95% of CPF, 95% of CPF of the 2 hour Plt for a week
  • statistics (density and cumulative probability function)
  • visualization of time functions (Pst, Plt), statistics of selected durations
  • CE proof
  • supply: 230 V 50/60 Hz max 50 VA
  • size: 320x210x300 mm
  • weight: 5 kg
