4_3 Understanding an objec['s magnetic field
FFgure 4 2
A ferromagnetic object has its own surrounding magnetic
fleld, as illustrated inFigure 4-2 The strength of an objecTs
magnetic (ield'a highest dose to the object itsel{ and reduces
with distance vntil it is negllgible.
As a magnetic object approaches Ferroguard Screener it will
initially be oui of range and the Visual Beamn will remain
green, as shown in Figure 4-3A.

As the object moves nearer, (Figore 4-3B), the Binqe
magneticfield is detec[ed so the beamn tums amber and
the magnitude display increases.
As it moves nearer still, the magnetic signal will continue to
lncrease, and the magnitude dlsplay will rise until lt reaches
the top of its scale. At that point the lights wm red as shown
in Figure 4-3C.

Please note- Reduun the sensitivit of the Ferw uard
9 Y 9
Screener will reduce rts effectiveness. Sensitivities should
only be reduced when there are no locatfons at which the
Ferroguard Screener Beamn will stay green.
There are two sensiCivify dials at the bottom of
the Ferroguard Saeener, one which controls the
amber threshold, and one which mntmis the red
threshold.
As standard 6oth dials will 6e set to 10 (most
sensitive).
You will have been supplied with a small
saewdrivery this is can be used m rotate the
sensitivity dials.

There is a third dial which allows the user to tum on an
audible alert which will sound when the beacon tums red
If at your chosen location the beamn does not stay
green then you can reduce the sensitiviTy by �
following the instruc[ions below.
�
1) Usingtheadjustmentscrewdnverpwvided, �
rotate both the amber and red dials counter
dockwise by one dick so they are set m 9. �
2) Press the screen bvtton, move back b' (2m) and
observe the beacon and magnimde dlsplay-
3) If the beamn stays on green then the adjustment
is mmplete.
If you still see regular flickers of amber or red, then
repeat steps 1 and 2(Turn 6oth dials to down 1 dick and
observe) until you achieve steady green.
If you find you have to adjust the sensitivities to b or below,
please contact Metrasensfor advice.

Annualtc IingbyMehasensaPP/ovedFeimguardtechnicians.
Metrasens or your bcal distribumr offer a rervice contract that
indudes annual inspec[ion and testing. During inspection our
approved technlcian will ensure the rystem Is working to Its
full specification. Many hospitals adopt this as thelr only
formal procedure and do not conduct their own testing,
particulady if they have a 4ixed regular MRI staff. The reason is
that regular staff members very qulckly leam the behavlors of
Fermguard - and in particular how it responds to certain
stimuli from ierromagnetic o6jects in the vicinity. A rystem
failure would be immediately obvious to them. Less obvious
would be a slow reductlon in sensltivity - in (acY this may not
be at all apparent unless It was faldy severe. However, this
mode of failure has never o¢urred in practice so far.
We view this option as being the minimum acceptable testing
regime. Irrespective o( further testing options Metrasens
recommends all Ferroguard sites to have this service connact.
