      • MAX HOLD sets the display to hold the maximum value measured.
      • MAX DECAY sets the display to hold the maximum value measured for a certain amount of scans.
      • AVER 4 sets the amount of running averaging to 4.
      • AVER 16 sets the amount of running averaging to 16.
    • STORAGE
      • STORE TRACE writes the current measurement to the green trace.
      • CLEAR STORED removes the stored trace
      • SUBTRACT STORED subtracts the stored trace from the current measurement.
      • NORMALIZE will store the current scan and subtract this stored scan from future measurements.
    • LIMITS
      • LIMIT x where x=1..6. Activates the input menu to set one of the maximum 6 limit line segments
