Special Note: |

|
As a general rule, shore-calibration is only required for |
|
|
|
|
|
|
|
|
reference equipment/instruments. |
|
|
|
|
|
|
|
|
Calibration check is only recording the actual reading against |
|
|
|
|
|
|
|
|
a reference instrument. |

|
|
|
|
|
|
|
Throughout this section, a shore-calibrated UTI/Hermetic |
|
|
|
