flow passing the transducer. The correct pulse rate is calculated by:
19000 x indicated speed (e.g. 4kn) = 15.200 pulses/nm
actual speed (GPS) (e.g. 5kn)
Measurement units – the user may select the displayed units to be one of the

Navigation simulator - the chartplotter function features a built-in navigation
simulator which can be used for demonstration purpose or for practicing 'live'
navigation in 'off season'.
Navigation to cursor or waypoint, in route or in track is started as described in
chapter 6. The navigation simulator is started via the NMEA interface setup:
Press [MENU],[7],[2], [PAGE]; go to 'OFF' next to 'External pos data:' and
press the [-] key to toggle to: Dead reck.; move cursor to the right and enter a
speed value of e.g. 10 knots; press [ENT] twice.
The ship symbol will now 'sail' to the point of destination directly or via the
route you have selected and you can see how the alarms and automatic way-
point shift all work, as if you were sailing yourself. You can also simulate
making a track trailing the ship or plotting eventmarks, etc. as the ship is 'sail-
ing'.
