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 –

), it 

is suggested that the datalog files be periodically deleted from the SDS data logger.  All survey data that 

is captured on the data logger is transferred to the PC using the SDS Reporter software and can be 
reviewed at any time from that PC.

  

Any data logger that retains datalog files for more than one hundred 

ten (110) days, or roughly three and a half (3 ½) months, will begin to experience issues with the data 
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
