Calibration

OR 52-7

According to the IMO Resolution MEPC 107 (49), section 4.2.11, the measuring accuracy of the 15 ppm

bilge alarm must be checked when the equipment is inspected in order to obtain the extension of the

period of validity of the IOPP certiﬁcate (5 years) as speciﬁed by the manufacturer.

For this inspection the measuring transducer ORG 12 must be exchanged.

Please order a replacement for the measuring transducer ORG 12 (stock code 389 427), indicating the

serial number, in good time before the IOPP certiﬁcate expires.

Before exchanging the measuring transducer undo the central screw of the connectors for the light

emitter/receiver and for the purging valve and detach the connectors.

Remove the measuring transducer and mount the replacement equipment.

Attach the connectors to the light emitter/receiver and the purging valve and tighten the central screw.

Repeat the commissioning procedure.
