4.1.14 Tide Process: J1/J1+/J2/J2+/J3/J3+/J4/J4+/J5/J5+
Function It is a menu for servicemen.
Used the J3 position usually.
Operation Standard Menu: [MENU] key/Menu screen/Measure setting≫/[ENT] key/ Tide
Process: J1/J1+/J2/J2+/J3/J3+/J4/J4+/J5/J5+
About current operation
It is a setting item which functions on the operation of a current value.
The variation in a current value becomes small so that a numerical value is large, but
the influence of the following comes out.
- The probability that the function to eliminate an unexpected value stops working
correctly becomes high.
- Since the tracking to change of a current becomes quick, it may not be stabilized
depending on a situation.
4.1.15 Shallow Water Mode: Standard/Shallow water /Auto 1/Auto 2
Function A standard/shallow sea is selected according to the depth region
which measures a current.
Use as standard usually.
The Auto 2 is a setting for servicemen.
Operation Standard Menu: [MENU] key/Menu screen/Measure setting≫/[ENT] key/Shallow
water mode: Standard/Shallow water /Auto 1/Auto 2
About shallow water mode
It is a setting item which functions on the measurement limit in a shallow sea
region.
If shallow water mode is selected, measurement of a current will be attained at the
place of bottom depth shallower than usual, but the influence of the following
comes out.
- A possibility that a current value will become unstable at a place about deeper
than 50 m in the bottom of the sea depth becomes high.
- A possibility that a bottom tracking ship speed will become unstable at a place
about deeper than 50 m in the bottom of the sea depth becomes high.
- At the bottom of the sea depth about deeper than 50 m, a possibility of losing the
bottom of the sea becomes high.
- Compared with the case of a standard, the accuracy of a current value may
become low.
- Compared with the case of a standard, the tracking performance of a current
value may become slow.
The Auto 1 changes standard and shallow sea mode automatically according to
bottom of the sea depth.
The Auto 2 is an item for servicemen. Please do not use it.
