8. ACCESSORIES
8.1 Units of measurement and instrument
identification
All BA304ND indicators are fitted with a blank
escutcheon around the liquid crystal display. This
escutcheon can be supplied printed with any units
of measurement and tag information specified at
the time of ordering. Alternatively the information
may be added on-site via an embossed strip, dry
transfer or a permanent marker.
CAUTION!
The enclosure should only be dismantled
when the instrument is de-energised, or
there is no risk of a flammable
atmosphere being present. Dust or
water must be prevented from entering
the enclo-sure. Before replacing the
control & terminal covers ensure that the
sealing gaskets are undamaged and free
from dirt and foreign bodies.
To gain access to the display label remove the
terminal cover by unscrewing the two 'A' screws
which will reveal two concealed 'D' screws.
Unscrew the four 'D' screws and carefully lift off the
front of the instrument enclosure - Fig 4 shows the
location of these screws. Add the required legend
to the display label, or replace with a new pre-
printed self-adhesive label which may be obtained
from BEKA associates. Before reassembling
ensure that the sealing gaskets are undamaged
and free from dirt and foreign bodies.
The BA304ND can also be supplied with a blank or
custom engraved stainless steel plate secured to
the front of the instrument by two screws.
8.2 Internal Calibrator
The BA304ND can be supplied with an optional
internal calibrator which simulates 4 and 20mA
input currents. This allows rapid calibration without
the need for external instruments or disconnection
from the 4/20mA input current, but it is not a
substitute for calibration with a traceable external
current source. Fig 6 shows the position of the
calibrator link which is located behind the
instrument control cover.
The plug-in root / linear link shown in Fig 6 must
always be in the root position when an internal
calibrator is fitted. An internal calibrator can not be
fitted to an instrument with a root extractor.
