4.4.7 Menu T, Test menus
The test menus are used to force one specific or all built-in self-diagnosis and explicitly show
the result in the NWW-82 Display Mode window. To be able to make changes to sub menus
write access must be activated (changed to ON) before menu is entered.
Note!! Test menus T2 to T5 will force the internal self-diagnosis to be executed much more
often (every second speed measurement) than during normal operation.
This might degrade the accuracy of the calculated speed while the test is active.
T0 TEST
WRITE ACCESS OFF
T1 SIMULATION
DISABLED
Menu T1 outputs a simulated speed instead of the real speed measured by the
log.
Use + to change menu to ENABLED and then Enter to start speed simulation
and go to next sub-level where the simulated speed value may be changed.
Note!! The real measured speed to all systems and displays on the ship will
be replaced by the simulated speed.
T1.1 SIMULATION
SIM.SPD=8.00KN
In menu T1.1 the simulated speed may be changed.
Use – or + to change the speed and then Enter to save.
