2.3 The Measurement Window
During normal operation you will use the Measurement Win-
dow to view your measured data. It provides several kinds
of information about your settings and measurements.
1. The bottom end of the measurement range (in dB): all
sound below this level will register as under range. To
change the measurement range, press while meas-
urement is stopped.
2. Quasi-analogue display: shows a graphical representation
of the current sound pressure level. It is updated 15 times
a second.
3. The upper end of the measurement range (in dB) and
overload indicator: Peaks above this level will trigger an
overload warning. If an overload has occurred in the last
one second, this number will change to read “OVL” for
the duration of the next second. If an overload has oc-
curred at any time during a measurement in progress,
then this number will blink (this is called a “latched
overload”). To change the measurement range, press .
