n: Number of pulses per rotation (1 to 1000)
Pulse input period
interval)
100 ms or greater (50 ms or greater during high and low
interval)
Slope Set rising/falling for each channel.
Measurement mode Integration (addition, instantaneous), rotational speed
Integration Addition: Counts the number of pulses input from start of
measurement.
Instantaneous: Counts the number of pulses input within each
recording interval (integrated value is reset for
each rotational interval).
Rotational speed r/s: Counts the number of input pulses during 1 s and
calculates the rotational speed.
r/min.: Counts the number of input pulses during 1 min. and
calculates the rotational speed.
Smoothing function Select value from 1 s to 60 s (valid only when set to rotational
speed and r/min.).
Logic input Measurement mode Records 1 or 0 for each recording interval.
