•
In the bottom left part appears the highest NR curve not exceeded by the measured
spectrum. That is the NR curve that defines the measured noise.
•
In the upper part appears, for each octave band, the NR curve value not exceed in that
band. This information is useful to check which octave band has the maximum
contribution to the NR curve. That is to say, at last there must be one octave band with an
NR curve equal to the one corresponding to the measured noise.
By pressing
you access the numeric analyser mode.
NOTE: The functions values will be refreshed on the screen each second.
2.4.4 Stopping and pausing the measurement
By pressing
you can temporarily pause or halt the measurement process. The state
of measurement indicator will switch from to
.
While the SC-30 is in pause position ( )
you may continue consulting the measurements made up until measurement was paused. To
resume measurement, press
.
By pressing
stop the measurement process. The state of measurement indicator will
switch from to .
2.4.5 Consulting the measured data
While the SC-30 is not measuring ( ) you may consult all the measured functions.
This is done in the same way as the one in section
2.4.3. to display data while measurement
is in progress.
2.5 Overload and over range indicator
The SC-30 has an overload indicator for each function. If a function was overloaded during
measurement, the ^ sign will appear before its value. When a function has registered
overload, its reading is incorrect.
While there is an overload, the sign
will appear in the bottom right-hand corner of the
screen.
When over appears in the indication of the value of a function, this means that the measured
value exceeds the upper limit of the measurement range (over-range). When this happens,
the maximum range of the SC-30 has been exceeded and the actual level cannot be known,
thus any such measurements should be discarded.
