Radio Shack Sound Level Meter User Manual

14
Controls
Follow these steps to select the desired
response, weighting, and range.
1. Set
RESPONSE
to
FAST
if the sound
source you want to measure consists
of short bursts or if you want to mea-
sure only peak values. Or, set
RESPONSE
to
SLOW
if you want to
measure average sound levels.
2. Set
WEIGHTING
to
A
if you want to
measure noise level or
C
if you want
to measure sound levels of musical
material.
3. Set
RANGE
to the highest setting (
120
dB
) then adjust it downward until
there is significant deflection of the
needle. For the greatest accuracy,
always use the lower of any two pos-
sible settings.
For example, if
RANGE
is set to
80 dB
and the meter reads
–5
, reset
RANGE
to
70 dB
so the meter reads
+3
, for an actual sound level of 73
dB.
Important:
For meaningful readings,
any particular sound to be measured
must be at least 10 dB louder than
the background noise level.
