Tide sensor 5217/5217R
The sensor current drain depends on the sampling interval, the output interval (S), the tidal averaging period (T), and the
sampling frequency (Fs) refer to Table 3-2 for current drain in each mode.
Note! If
Enable Tide
is
No
(Tide output parameter are disabled), then the sensor power consumption is similar to
the power consumption of the Pressure sensor 4117/4117R, refer chapter 3.1.
Table 3-2 Power consumption of the Tide Sensor 5217/5217R when Enable Tide is Yes, and the assumptions stated in the
beginning of Chapter 3 are true.
