Internal Clock Accuracy on Deckma Hamburg Bilge Alarm Monitors
The OMD series MEPC.107(49) 15ppm bilge alarms are equipped with an electronic data recording device that uses GMT(UTC) as the standard time. This device has a fixed internal clock that cannot be modified or calibrated by the user.
The internal clock is verified to be within +/- 2 minutes of GMT during the final quality check, and it is expected to maintain this accuracy for a long time, with minimal drift. However, depending on the environmental conditions and especially temperatures, the internal clock may deviate from the actual GMT time over time. Minor deviations of a few minutes are not a problem. For larger deviations, it is advisable to document the difference from GMT e.g., once a year, for clarity and proper interpretation of the data.
Only if the deviation exceeds +/- 10 minutes, it is recommended to return the device to the factory for clock adjustment. If sudden changes in deviation from GMT occur, it is recommended to return the device for diagnosis/repair.

FAQ
Can the internal clock on Deckma OMD 15ppm bilge alarms be adjusted or calibrated by the user?
No. The OMD series MEPC.107(49) 15ppm bilge alarms use a fixed internal clock set to GMT(UTC), and the user cannot modify or calibrate it. Factory clock adjustment is recommended only if deviation exceeds +/- 10 minutes or sudden changes occur.
How accurate is the internal clock on Deckma OMD bilge alarm monitors?
The clock is verified to be within +/- 2 minutes of GMT during final quality check, and it is expected to maintain this accuracy for a long time with minimal drift. Environmental conditions, especially temperatures, may cause it to deviate over time.
What should I do if the Deckma OMD internal clock deviates from GMT?
Document larger deviations from GMT, for example once a year, to support clarity and proper interpretation of recorded data. Minor deviations of a few minutes are not a problem; if sudden changes in deviation occur, return the device for diagnosis or repair.
When should a Deckma OMD bilge alarm be returned to the factory for clock adjustment?
Return the device for factory clock adjustment only when the deviation from GMT exceeds +/- 10 minutes. If the deviation changes suddenly, return the device for diagnosis or repair. The clock cannot be modified or calibrated by the user, and documenting larger deviations annually aids data interpretation.
Does the Deckma OMD bilge alarm internal clock use local time or GMT?
It uses GMT(UTC) as the standard time. The electronic data recording device has a fixed internal clock that cannot be modified or calibrated by the user. Clock accuracy is verified to be within +/- 2 minutes of GMT during final quality check.
