Introduction
Your digital sound level meter provides automatic or manual ranging from 30 to
130 dB. The unit meets IEC 61672-1 Class 2 standards, and features 0,1 dB
resolution.
A background noise absorber permits you to measure sound levels accurately
even in the presence oft high background noise. The meter allows you to select
between fast and slow response times and A and C weighting. A maximum hold
function is provided. Jacks on the meter provide both AC and DC analogue
output,an internal data storage for 32000 measurements while the USB interface
allows you to capture sound level data on a PC.

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.
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.
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
Recording the maximum and minimum measurements
-
MAX/MIN button: Maximum and Minimum hold Press this button for one time to enter MAX/MIN measurement, ‘MAX’ will appear on LCD, maximum
sound level will be captured and held until higher sound level is captured. Press the button again, ‘MIN’ will appear on LCD and minimum sound level will be captured and held until new lower sound level is captured. Press the button one more time to exit MAX/MIN measurement. -
HOLD button: Press “HOLD” button, The hold function freezes the reading in the display.
-
Power button: Turn the meter power ON/OFF External DC 9V power
-
supply terminal: For connection with DC 9V power supply.
-
Aperture size: external diameter: 3.5mm, internal diameter: 1.35mm
-
USB interface: USB signal output is a 9600 bps serial interface.
AC/DC signal output:
- AC: Output voltage: 1Vrms corresponding to each range step.
- Output impedance: 100Ω
- DC: Output voltage: 10mv/dB
- Output impedance: 1KΩ
Selecting automatic and manual ranging
The meter features 4 measurement ranges:
- AUTO: 30 … 130 dB
- LO: 30 … 80 dB
- MED: 50 … 100 dB
- HI: 80 … 130 dB.
When you turn the meter on, it will be in manual range mode. This is helpful when you know the measurement range in advance. The meter will be able to take readings more quickly, because the unit does not need to first establish the range before displaying the measurement. You can also set the range automatically. In this mode, the meter will adjust the measurement range automatically for accuracy. The two digit number to the left of the bar graph on the LCD will show the low end of the current range. This is helpful when you know the measurement range in advance. The meter will be able to take readings more quickly, because the unit does not need to first establish the range before displaying the measurement.
To activate the AUTO-range mode:
When measuring sound levels, press the LEVEL (7) key until “AUTO” appears in
the LCD display. Note that the two digit number to the left of the bar graph
will change to reflect the low of the newly selected range. To switch back the
manual range, please press the LEVEL (7) key again, until “AUTO” disappears
from the display.
