Period-averaging measurement specifications
Use PeriodAvg() to measure the period (in microseconds) or the frequency (in Hz) of a signal on a single-ended channel.
Terminals: U1-U12
Accuracy: ±(0.01% of measurement + resolution), where resolution is 0.13 µs divided by the number of cycles to be measured
Ranges:
- Minimum signal centered around specified period average threshold.
- Maximum signal centered around data logger ground.
- Maximum frequency = 1/(2 * [minimum pulse width]) for 50% duty cycle signals
