To measure high frequency, select ‘High Frequency’ in the drop-down box:
Also, set the CAN ID where The K Box will transmit the result.
Set the Rate you wish to measure at:
The Rate parameter affects measurement precision.
The K Box measures high frequency using a pulse counter for the selected Rate and normalises it to 1 second to calculate the value in Hz = 1 s * N pulses / Rate.
The K-Box averages measured values if the high-frequency changes for a measurement interval (Rate).
The sensor sends at a frequency of 10kHz for 60ms, and the K-Box registers 600 pulses (60ms * 10kHz).
The sensor sends at a frequency of 8kHz. For 40ms, the K-Box registers 320 pulses (40ms * 8kHz).
For the whole measurement interval of 100ms, The K-Box registers a total of 920 pulses.
Normalised to Hz, the measured frequency is 9.2kHz (1 s * 920 pulses / 100ms).
If the Rate is set to 1000 ms, the measurement's accuracy will be 1Hz.
