Specifications
Computes the deceleration condition in realtime when the pulse input is cut off.
Can be specified when measuring the frequency, RPMs, RPSs, period, and velocity
Sets the frequency to 0 after a certain time elapses after the pulse input is cut off.
Stop interval setting: Set in the range of 1.5 to 10 times (10 settings) the period of the
pulse measured last
Can be specified when measuring the frequency, RPMs, RPSs, period, and velocity
Computes the moving average of the measured data using the specified time
Specified time: 0.1 to 1000 ms (0.1 ms resolution)
Can be specified on all measurement parameters
Performs frequency measurement per specified number of pulses. When fluctuation
exists periodically in the pulse interval, the fluctuation can be eliminated.
Specified number of pulses: 1 to 4096
Can be specified when measuring the frequency, RPMs, RPSs, power supply frequency,
period, pulse integration, and velocity
Observe fluctuation with respect to the offset frequency
Offset range: Can be set up to 1000 times the maximum div value
