push of a button.
• Select the LOG to START and STOP the logging function. The LED will flash
when the data sample is stored in any logging mode. A log status icon will also
appear at the top to acknowledge a logging session is active. The log counter will
list how many measurements have been recorded in the current log file.
• After the log session has begun, the file name will appear on the FILE row.
• You may select under MEDIA to either store data logged files to an SD card if
one is inserted or to INT which is the internal memory.
• Select LOG FILES to view all saved files. See view of saved files section for more
details.
• If the trigger has been selected to be Manual from the LOG main menu, the
screen above will appear.
• You can change the ending of the log to be either a manual end under STOP, or
you can set the STOP to end after a duration.
• If DURATION is chosen the programmed duration determines how long the log
session will last. It may be set from 1 to 1,440 minutes.
• If the TRIGGER has been selected to be Event from the LOG main menu, the
screen will appear as shown.
• The trigger’s source parameter must be selected to determine the levels for the
event.
• LEVELS provides initiation points where the trigger will begin a log operation.
• The auto trigger EVENT settings can begin INSIDE or OUTSIDE the LEVELS
trigger band.
• Setting a PRE-TRIG setting to anything other than 0 will provide data recorded to
the file for that time period prior to the event trigger initiation.
• POST-TRIG sets the duration after the auto trigger event of the log session.
• If the MIN UPDATE is set to anything other than 0, a data point will be captured
at the time of the MIN UPDATE even if the TRIGGER threshold has not been
reached.
• The PRE-TRIG and POST-TRIG can be adjusted over a time period, dependent
on the sample rate, while the MIN UPDATE can be set from 0 to 60 minutes.
If Single is chosen, no other parameters are necessary to be programmed. This
mode will allow the right soft key located under STORE in the log hot key home
display to save a single data point into a file. Each subsequent data point will
continue to be stored in that same file until a new file is created in the Log Settings
Trigger Menu shown above when operating a new file, the user can name the file.
