32. Survey Deviation Alarm Log
The survey deviation alarm log will log all instances where the temperature of one of the survey channels
goes above or below the deviation band. The alarm log is on a one-minute update, so any alarm would
have to be present for more than a minute to be logged. The start and stop time of the alarm is listed at
the top of the screen on the line “AL 1 Start at”. The screen will display the each channel and which
channel was high or low. This log will be cleared out when the next survey is run.

data, the message will change to “Clearing complete.” If there was an error, the SDS instrument will
display “File error -13”. For SDS firmware versions 1.09 or lower (SDS menu 13 –

logger. Datalog files can also be deleted by using the SDS Download Surveys and Data menu option
on the SDS Reporter software to bring up the survey download screen. From the Download screen, the
