12 Using the multi‐setting transmitter
12.1 Recommendations
The multi‐transmitter must be used:

In combination with a SDT270 receiver;

Outside any classified zone requiring intrinsic and fireproof safety.

Away from discharge of water and must never be immersed. It is important to prevent any foreign bodies entering
the ultrasonic transducers, such as grease, dust, etc.

Within hygrometric and temperature limits stipulated in the technical characteristics.
Note: If necessary, the transmitter can be protected / covered by thin / fine mesh cloth (e.g. nylon stockings) to prevent
dust from entering into the transducers when working in a dusty atmosphere.
12.2 Working position
When preparing for testing the weathertightness of hatch covers and determining the OHV (Open Hatch Value), the
multi‐transmitter should be placed, ideally, in the center of the tank top.
The multi‐transmitter covers an operational spherical volume of 20 meters (60 ft) around its position. For larger
volumes, the multi‐transmitter should be moved several times; it is then necessary to take a new OHV (Open Hatch
Value) measurement after having repositioned the transmitter.
If the hold is not empty, the multi‐transmitter can be placed on top of the cargo.
12.3 Powering On
Note: The battery packs are charged in our factory for test purpose but
the battery packs are discharged before being dispatched, because of
international air transport legislation. Upon reception, the battery packs
should be charged.
The equipment is powered on by pushing the switch to the ON position
(1). The operating light (2) should be lit (if this is not the case then refer
to chapter 14 The multi‐transmitter operational problems).
The volume covered by one multi‐transmitter.
The zone covered by the multi‐transmitter
when set to various points.
The correct position of the multi‐transmitter.
The on‐off switch (1) and battery control indicator (2).
