Explanation
•  Selecting the Input Range of the Revolution and Torque Signals
  Two types of range settings are available: fixed and auto.
  •  Fixed Range
Select the input range from the following:
20 V, 10 V, 5 V, 2 V, or 1 V
  •  Auto Range
  Select ON for the auto range setting to enable auto range. The range changes 
automatically depending on the amplitude of the input signal.
  •  Range Increase
•  When the rotating speed or torque data exceeds 110% of the current 
measurement range, the measurement range is increased.
•  When the peak value of the input signal exceeds approximately 150% of the 
measurement range, the range is increased.
  •  Range Decrease
  When the rotating speed or torque data is less than 30% of the measurement range 
and the peak value of the input signal is less than 125% of the next lower range, 
the measurement range is decreased.
Note
When non-periodic pulse waveforms are applied during auto range, the range may not remain 
constant. If this happens, use the fixed range setting.
