The compass adjustment should be carried out by an experienced compass adjuster!
Please be be aware to carry out a reliable adjustment because this makes your
navigation safe. Steering by use of a non adjusted compass may because grounding
or collision!
Optional there are two types of B+C corrector devices:
Turning correctors and corrector magazines
1. The turning correctors (#18165) consists of two brass rods with fixed magnets located
in the base of the compass binnacle. One rod is parallel to the ship`s fore and aft (the
B-corrector) and the other is parallel to the atwardship direction (the C-corrector). A
detailled description will be included in the range of delivery if this corrector is mounted
to your compass.
2. The corrector magazines (#18150) are separate with delivery (see above foto). One
corrector magazine is for B and the other for C-correction. You will find in total 2
magnets when removing one of the U-shaped covers. A detailled description will be
included in the range of delivery of this corrector.
The heeling corrector is a magnet tube that should be installed below the compass with the
magnet tube vertically. The magnets are inside the tube. For details refer to the instructions
included in the delivery of the heeling corrector.
For detailled-questions concerning the procedure of compass adjustment refer for example
to: HANDBOOK OF COMPASS ADJUSTMENT, Pub. 226, U.S. Defense Mapping Agency.
Compass adjustment has to be checked from time to time.
Especially in case of lightning struck, grounding, welding works…..the compass
adjustment has to be repeated.
Operation
The main lubber line is orientated to ship`s ahead direction. Course reading free of parallax
error will be provided if the front and the back part of the lubber line are superposed.
Before cruising make sure that the compass is well adjusted!
Note that you have to apply the local magnetic variation to calculate the true heading
(the heading found in the sea chart) from the compass heading
. The local magnetic
variation is printed on the charts of the sailing region.
Generally (if there were no contrary advise to Cassens & Plath with order) the directional
system of the compass is balanced for northern hemisphere. If the vessel then sails in
southern waters a tilt of the directional system may be occure. The southern part will be
lowered. This is caused by the vertical magnetic field which is contrary to that in northern
hemisphere. A small tilt of the directional system will not influence the operation of the
compass.
