3. Accuracy of hours meter
This unit does not use a battery backup CPU nor any special device for storing the hours meter data.
The hours meter data stored contains a small amount of allowable error.
This unit automatically stores hours meter data in the flash memory so that the storage interval becomes geometric reality.
The nth storage later from the power ON state is performed 1.5
n
_
1
minutes from the previous storage.
The maximum interval is 24 hours. The data will be saved in the memory after extrapolation arithmetic of half of the next
storage interval.
The error of the hours meter data stored is about
±
20% (maximum) when n is large.
The cleaning and thread counter are not stored in the hours meter everytime the counter is increased, but is updated at the
above storage interval.
