The choices within the “Time His-
tory” menu include: “Beginning”,
“Ending”, “Find”, “Graph”, and
“Settings”. “Beginning” moves you
to the first Time History sample of
the active measurement. “Ending”
moves you to the last Time History
sample of the active measurement.
“Find” lets you choose a Time His-
tory sample to move to within the
Time History display. The “Graph”
settings operate the same as was
shown earlier in the “SLM Current”
section. You can control the graph
level and scale of the Time History
using this feature. “Settings” is the
area where you can modify the
parameters associated with acquir-
ing the Time History measurement.
Step 1 From within the “SLM Time History” win-
dow, press c.
As an exercise, we will set the 824 to gather a time his-
tory of the Leq in 10 second samples. We will also set
the instrument up so that the Lmax is acquired simul-
taneously.
Step 2 Press d to highlight “Settings”.
The choices here are: “Hist Enable”,
“Hist Period”, “Period Units”,
“Other Level”, and “Resolution”.
The “Hist Enable” activates or deac-
tivates the Time History measure-
ment function.
Step 3 Next, press c (or r) to enter the “Time His-
tory” settings menu.
