Status Field

The Status Field has been extended to include an extra line of information below the two

existing lines of information covered previously in the Sound Level Meter and Frequency

Analyzer (see Fig.11.3).

This extra line of information allows you to:

• Select whether the results of the Total measurement from the Logged measurement, or

from the Logged(100 ms) measurement are displayed. Select Total to display the

measurement parameters of the Total measurement in all the views – the Broadband and

Spectrum views will then display parameters or spectra similar to the Sound Level Meter or

Frequency Analyzer. (The Profile view will be empty, because the Total measurement

contains only a single set of parameters). Select Logged to display the measurement

parameters from the logging intervals. The cursor in the profile selects which logging

interval is displayed in all the views. Select Logged(100 ms) to display the L

Aeq

, L

or L

in the profile from the 100 ms logging intervals. This setting does not display spectra or

parameters in other views

• View the start time of the measurement (for Total) or the start time of the current logging

interval (for Logged or Logged(100 ms) if measuring and the profile is not frozen) or the

start time of the logging interval pointed out by the cursor. Tap the Start Time in any of the

views to select data from another logging interval

• View whether the display of the profile during the measurement is frozen or not. When the

icon is “animated” the display is being updated with new logged data during the

measurement. You can freeze the display update by tapping on the icon. This also freezes

the icon. Tap the icon again to unfreeze the display

• Step forwards or backwards through the logging intervals on all displays, using the and

icons. (The icons are also connected to the profile cursor, so that any corresponding

movement backwards or forwards through the intervals in one display will be reproduced

in the other)
