Seismology Instruction with the AS 1

Helicorder Screen Overview

     The window that appears when the program is launched is 

called the helicorder screen.  The recording emulates what appears 

on a drum recorder. 

   Using default settings each horizontal line represents an 

hour.  The current time (UTC) is found in the bottom left 

corner of the screen.  The trace should be recording along 

the bottom hour line.

               The date is posted on the 00 hour line.  The scroll bar along the right side of the 

window can be used to scroll back through the earlier recorded data.

   The sampling rate is the data per second that are sent from the seismometer to the 

computer.  It should be a number between 6.1 and 6.2 samples per second for the AS 1.  

This rate is determined when the introduction screen is visible, by counting the number 

of data points that arrive in 5  seconds.
