ALIBRATION CHECK
9.1 S
CHEDULE
Two items needs to be addressed when setting up the maintenance schedule for the BilgMon488:

Expiry date of the factory issued calibration certificate.

Occasionally a calibration check is required within the validity period of the factory issued
calibration certificate.
The following two subchapters explain how to resolve these two items.
9.2 C
ALIBRATION CERTIFICATE EXPIRY DATE
If the factory issued calibration certificate expires, the SENSOR unit must be replaced.
The SENSOR of BilgMon488 is designed to be easily replaced by the crew, see 9.4 Sensor unit
replacement. Replacement does not require any adjustments of the MASTER unit setup.
Each new SENSOR is accompanied with a new factory issued calibration certificate.
9.3 C
ALIBRATION CHECK REQUIREMENTS
On occasion ships may be required to perform a "calibration check" on their units. This might be
required to take place at shorter intervals than the validity period of the factory issued calibration
certificate.
Calibration check can be achieved in the following ways:

Checking calibration with a "Calibration Check Kit".
(Requires ordering a kit or consult a service agent)

If the calibration check fails (calibration values are not within limits), a new SENSOR must be
installed.
