  About BT・WT    Average time 3   
It is a setting similar to "BT・WT・Tide Average time1". 
Although  tracking performance  is as quick as the numerical value of a setting 
being small (or short) and stability becomes high in the numerical value of a 
setting being large (or long). However, since other calculation items and a result 
have correlation, the expected setting result is not necessarily obtained.

  About Tide Response time 2   
Tracking performance immediately after the start of current calculation is mainly setting. 
Tracking performance may be made quick when the bottom of the sea depth measures 
a current at the place which becomes deep suddenly. 
Tracking performance becomes quick, so that a numerical value is small, and tracking 
performance becomes slow, so that a numerical value is large. 
If tracking performance is too quick, in the state where beginning displays in a current 
value, an actual current and display do not suit in many cases. 
When the current at the time of a display start is not stabilized, it sets to a large value.
