Setting the Measurement Item: Function
The following nine items are available.
• Frequency
Tw(s)
Frequency (Hz) = 1/Tw (s)
Measurable range: 0.01 Hz to 200 kHz
• Period
Period (s) = Tw (s)
Measurable range: 5 µs to 50 s
• RPMs/RPSs
F(Hz)
Nr: The number
of pulses per rotation
RPMs = Frequency (Hz)/the number of pulses per rotation
(Nr) × 60
Measurable range: 0.01 rpm to 100000 rpm
RPSs = Frequency (Hz)/the number of pulses per rotation
(Nr)
Measurable range: 0.001 rps to 2000 rps
• Duty Cycle
Thigh(s)
Tw(s)
Tlow(s)
Duty cycle (%) = Thigh (s)/Tw (s)
Or, duty cycle (%) = Tlow (s)/Tw (s)
Measurable range: 0% to 100%
• Pulse Width
Thigh(s)
Tlow(s)
Pulse width (s) = Thigh (s)
or pulse width (s) = Tlow (s)
Measurable range: 2 µs to 50 s
• Power Supply Frequency
Tw(s)
Power supply frequency (Hz) = 1/Tw (s)
Resolution: 0.01 Hz
Measurable range: (50 Hz, 60 Hz, or 400 Hz) ± 20 Hz
•P&se Integration (Distance/Flow Rate)
N (count)
l
Pulse integrated value = N (count) × physical amount per
pulse (I)
Set the physical amount per pulse (I) to distance or flow rate.
A suitable user-defined unit can be assigned to the specified
physical amount.
Measurable range: Up to 2×10
9
counts
• Velocity
Tw(s)
Distance
per pulse (l)
Velocity (km/h) = Distance per pulse l (km)/Tw (s) × 3600
Velocity (m/s) = Distance per pulse l (m)/Tw (s)
The distance and unit can be user defined (angular velocity,
etc.).
Measurable range: F (=1/Tw) = 0.01 Hz to 200 kHz
