Measurement
Important
L
AI
is the time weighting level, but the display is
updated when processing is started by pressing
the Start key. When processing stops, the dis-
play update also stops. To measure L
AI
only,
setting of the "Meas. time" item to "Manual" is
recommended.
Note
It is also possible to use the Mode key during mea-
surement to read the equivalent continuous sound
level up to that point. (This applies only to the nu-
meric level display. The bar graph indication shows
the sound level.)
Changing the A/C/FLAT or Fast/Slow setting after
measurement is completed has no effect on the dis-
played processing result.
