Simple Setting and Reference Value of Measurement Setting
The reference value of a measurement setting according to situation is introduced.
Note: By setting a reference value, it does not guarantee that a situation improves.
In the tidal current measurement mode (all screens except fish finder mode)
Filter setting using STC knob is possible.
Filter setting by the STC knob,
One-dimensional setting (-15 to 0 to +6) with the STC knob is enabled.
In the past, adjustment of 7 kinds of parameters is necessary.
-15 : Shortest verage time (Respons is fast, not stable)
0 : Initial value (Respons is relatively slow, stabilized well)
+6 : Longest average time (Respons is slow, stabilized)
It is recommended to use between -10 and +1
In the following cases,
It may be improved by decreasing the setting value (shortening the average time).
· Tidal current value does not easily approach the true value.
· Tidal current display value is small continues.
· The respons is slow and can't detect the tide (current-rip
)
.
If it is set to less than -10, In most situations the display value of the tidal current does not stabilize
(large variation) and it is hard to use.
If it is not stable even if it is set to a value greater than +1, there are bad factors that affect
measurement.
By operating the STC knob, change the measurement setting value of 7 items.

After adjusting with the STC knob it is also possible to change every item by menu.
