Test names
0. Calibrations Port
1. Calibrations Starboard
Purpose
Sets the JIM steering and reverse gains to JETanchor settings
Calibrates the JETanchor control module mathematical zero speed setting to
the JIM zero speed set during blue ARROW commissioning. This minimises
vessel movement during autotune
Prerequisites

JETanchor system is installed
JETanchor Mouseboat is in control
JIM1 and JIM2 zero speed has been set
Required test area
Minor movement of vessel may occur
This test can be performed while the vessel is tied up alongside the dock
Expected system
behaviour
Engine is automatically set to idle
Reverse duct automatically moves up to +/- 15% of stroke length from the
zero speed position
Minor movement of vessel may occur
Approximate test time for a medium-size (twin HJ364) vessel: 30 seconds.
Test time is normally longer for larger vessels and may be shorter for smaller
vessels
Test procedure
Before starting the test, confirm with the vessel master that it is safe to take
control
The vessel master can abort an auto tune test and take manual control
of the vessel at any time, by moving the Mouseboat
Select test 0. Calibrations Port test or 1. Calibrations Starboard test, then
click Next when you are ready to start the test
Monitor vessel behaviour at all times during the test and abort the test if
