Pulse frequency at the maximum rate
Hz
- Pulses per reporting interval
- 3,000 pulses
- 32-bit maximum counter value
- 4294967295 counts
- Increments from zero before wrap
- 4294967296 increments
- Maximum represented total
- units
- Time to rollover at the maximum rate
- days
Use this prediction to plan a controlled source-meter reconciliation; it does not by itself diagnose every missed pulse.
Underlined figures are rounded. Select one to copy its full value.
Method and assumptions
Formula
pulse frequency = process rate × pulses per unit ÷ 3600; time to wrap from zero = 2^counter bits ÷ pulses per hourThe maximum represented unsigned value is 2^bits − 1, but a zero-start counter wraps after 2^bits increments. A zero process rate has no finite rollover time.
Limits of this result
- The result does not prove that an electrical pulse level, width or gap is compatible with an input.
- A matching predicted rate does not detect every bounce, wiring, power-loss or counter-reset fault.
- Use the source meter totaliser and a controlled reconciliation period as the acceptance reference.
