yachts. The comp ass permi ts up to 45° he eling and unlimited tilting for e and aft.

SILVA 100 /125 is suppli ed with a yellow mai n lubberl ine and two yellow a id lines 45 ° on each
side of t he main lubbe r line. It has a b uilt-in clin ometer +/- 45°.

The co mpass is del ivered with built-in il luminatio n.

PRODUCT OVERVIEW

The packaging includes:

• Compass unit

• Illumination

• Mounting kit

ILLUMINATION

This compass can b e supplied w ith illumination 12 V.
Adaptatio n to 24V-illu mination co nnected in s eries by a re sistor of 27 0 ohm, 0.5 W.

POSITIONING

SILVA 100 /125 should be p ositione d vertica lly or slopi ng (max 30°) . Vertical ly only, il a comp en­sator i s fitted.

BULKHEAD MOUNT

The co mpass shou ld be positi oned where it can be easil y read from al l angles, e ven in dark­ness w hen illumi nated. Posi tion the comp ass as far as possible aw ay from iro n objects o r other
disturbin g magnetic s ources as lo ud speakers, win dscreen w ipers, ins trument s etc.
NB! SILVA s electronic ins truments do not distur b the compas s.
When c hecking fo r magnetic di sturbance, use a n ordinar y SILVA handhel d compass , held in the
fore -and-aft direc tion aroun d the intende d mounting si te. In most ca ses 0.5 to 1 met re betwee n
the com pass and the s ource of dis turbance w ill be sufficie nt. Do not for get to switc h on all
elec trical eq uipment nea r the compas s when makin g this check .

MOUNTING

SILVA 100 /125 is intende d for flush mo unting.
The co mpass must be moun ted exactly at righ t angles to the boat’s l ongitudin al directi on.
NB! Do not t ake It for gra nted that for in stance a bulkhead is at a right angle to the b oats
longi tudinal dir ection. D rill a hole b y using the enc losed temp late. The co mpass must have a
certain mo unting dept h, otherw ise the comp ass’ expan sion membr ane is ettected, which c ould
lead lo leakage.

COMPENSATION AND DEVIATION

Comp ensation i s recommended, if t he deviati on is more than 5 degre es, when th e compass is
in its normal mounting position.
If the er ror is less than 5 de grees, it i s sufficient to produce a d eviation t able.
Comp ensation i s made with th e two compe nsation adjuste r screws ”E /W” an d ”N/S” in order
to redu ce the errors cau sed by iron ob jects or ot her source s of magnetic d isturbance. Th e
compe nsation ad juster scr ews are situated at t he compass lower f ront edge.
When c ompensat ing, the boa t should be in an a rea that is not affe cted by per manent- or ele c­tromagnetic disturbances.

1. Aim the boat d ue North an d turn the ”N/ S” screw until the compas s reading is 0°.

2. Aim th e boat due Eas t and turn the ”E/ W” scre w until the compass r eading is 90 °.

3. Aim th e boat due Sou th. If the compass d oes not show 18 0°, turn the ”N/S” s crew until th e
erro r is halved. (E .g. If the er ror is 6° - turn the screw until th e error is 3 °.)

4. Aim th e boat due Wes t. If the comp ass does not s how 270°, tu rn the screw until th e error is
halved.

5. Go through th e procedur e again and che ck the adjus ted values .

6. Check the compass e very 20 de grees and produc e a deviatio n table and de viation curve.

As the magne tic conditi ons in a boat ar e liable to cha nge, we reco mmend chec king of the com ­pass o nce a year and alway s after inst allation of equip ment which m ight affec t the compa ss.

NB! Do no t regard the c ompass as a n accurat e navigati onal inst rument un til the comp ensa­tion is c arried o ut and the dev iation ta ble is prod uced. Whe never in dou bt, pleas e seek the
advi ce of a compa ss adjust er!
