• Revolutions (rpm)/Revolutions (rps) (Revolution(rpm)/Revolution(rps))
Revolutions (rpm) = Frequency (Hz) ÷ pulses per revolution (Nr) × 60
Measurable range: 0.01 rpm to 100000 rpm
Revolutions (rps) = Frequency (Hz) ÷ pulses per revolution (Nr)
Measurable range: 0.001 rps to 2000 rps
F(Hz)
Number of pulses per rotation: Nr
• Periods (Period)
Period (s) = Tw (s)
Measurable range: 5 μs to 50 s
•
Duty Ratios (Duty)
Duty (%) = Thigh (s) ÷ Tw (s)
Or, Duty (%) = Tlow (s) ÷
Tw (s)
Measurable range: 0% to 100%
Thigh(s)
Tw(s)
Tlow(s)
• Power Supply Frequencies (Power Freq)
Power supply frequency (Hz) = 1 ÷ Tw (s)
Resolution: 0.01 Hz
Measurable range: (50 Hz, 60 Hz, or 400 Hz) ± 20 Hz
Tw(s)
• Pulse Widths (Pulse Width)
Pulse width (s) = Thigh (s)
Or, pulse width (s) = Tlow (s)
Measurable range: 2 μs to 50 s
Thigh(s)
Tlow(s)
• Pulse Integration (Pulse Integ)
Pulse integration = N (count) × physical amount per pulse (I)
Set the physical amount per pulse (I) to the distance or flow rate.
A suitable user-defined unit can be assigned to the specified physical amount.
Measurable range: Up to 2×10
