• 3. Select a different ID, make it the Active ID, and mod-
ify it as required.
Selecting a Different ID
Use the dand ukeys to highlight the desired ID and
make it the Active ID by pressing the
c Check key. This
will activate that ID, exit the Setup menu, and display the
main data view. The instrument is ready to perform a
measurement by pressing
s Run/Stop.
Accessing the Settings Menu
It is within the Settings menu and its associated Sub-menus,
that the settings associated with the measurement are
defined. Sound level measurements are made in the ISM
LOG, and SSA Instrument Types, so all of these will include
selections of RMS and peak detectors and broad band
frequency weighting. IDs based on the LOG Instrument type
will include parameters associated with automatic data
storage such as Interval and Time History periods and
threshold levels for triggering Exceedance Event data.
Report settings are also included in the Settings menu when
appropriate.
The following example will be used to illustrate the general
structure and utilization of the Settings menu and sub-
menus. Please follow this on your instrument. Since all
versions of the System 824 include the SSA Instrument
Type, we want to select the permanent ID SLM&RTA (SSA)
as the Active ID. Press
S to open the Setup menu.
Step 1 If the Active ID in your instrument is an unmodi-
fied version of SLM&RTA (SSA), press
c.
Step 2 If the Active ID in your instrument is anything
other than SLM& RTA (SSA), then highlight
SLM&RTA (SSA) and press
c to make it the
Active ID.
