3. Measuring Sound Levels
Sound levels are displaying both digitally and in bar graph.
* Press the ON/OFF key to turn the meter on. The meter will now begin measuring the current
sound levels. Point the microphone toward the source of the sound to be measured.
3.1. Selecting A and C weighting
When you turn the meter on, it will be in A weighting mode. A weighting enables the meter to
respond in the same manner as the human ear, which increases and decreases amplitude over the
frequency spectrum. Applications for A weighting include OSHA regulatory testing, environmental
measurement, workplace design and law enforcement.
C weighting is suitable for flat response measurements with no increase or decrease of amplitude
over the frequency spectrum. Applications for C weighting include the sound level analysis of
engines and machinery.
Press the A/C (9) key to toggle between A and C weighting. The symbol dBA or dBC will be
displayed on the right side of the screen to indicate the current mode.
3.2. Selecting the response time
You can select fast or slow response time to suit different applications and standards. For example,
most OSHA-related testing is done using slow response time and A weighting.
When you turn the meter on, it will be in fast response mode. Press the FAST/SLOW (5) key to
toggle between fast and slow response. A small fast or slow will be displayed on the right side of
the screen to indicate the current mode.
FAST: 1 time per 125 mS
SLOW: 1 time per second
