    • Programming Set-up: This will define the QNA-412 analyzer's operating mode. • File setup: This will define the variables that the QNA-412 is to record in its internal memory 8.1.- Programming Set-up for the QNA-412. There is a complete series of parameters that may be set in the analyzer: 8.1.1.- Voltage transformation ratio.

  • Page 21: Features Of The System

    This parameter is necessary for calculating the effective value of the signal in extreme quality systems. • 3 wire / 4 wire: The QNA-412 is designed to operate in installations with Neutral (4 wire) or installations without Neutral (3 wire). For this, the type of connection will be defined.
  • Page 22 • Overvoltage hysteresis: An overvoltage hysteresis is to be defined so that the voltage at the start of the overvoltage is not the same as the voltage at the end. Therefore an overvoltage starts when the overvoltage threshold is exceeded and ends when it is below the value defined by difference between the overvoltage threshold and the overvoltage hysteresis.
