1. GENERAL DESCRIPTION
Thanks for you’re selecting Personal Noise Dose Meter. To ensure that you can get
the most from it we recommend that you read the manual carefully before use.
The personal noise dose meter is test equipment to evaluate the noise condition of
working environment by measuring the accumulated noise exposure. With this test
data, company can ensure the related noise regulation is followed or decide whether
or not to apply certain noise reduction action to avoid the acoustic trauma and
noise-induced hearing loss occurs to the working personnel.

2. PRINCIPLE OF MEASURING ACCUMULATED NOISE EXPOSURE
DOSE is a parameter used to quantify noise exposure measured in a period, during
turns of % noise exposure relative to 90dBA for 8 hours.
i.e. 100% DOSE = 90dBA for 8 hours
This is known as the Criterion. Other criterion are available such as 100% DOSE =
85dBA for 8 hours to meet legislation in different countries.
If the person stayed in this environment for 4 hours, he would receive 50%DOSE.
Also if the noise level was say 93dBA, 3dB higher, a 100% DOSE would be
accumulated in only 4 hours, the above example is for a dose meter with 3dB
Exchange Rate, where a 3dB increase in sound level corresponds to a doubling
energy. A dose meter with 5dB Exchange Rate is also, available where the sound
must increase by 5dB to double the dose as required to meet noise legislation in
some countries.
3. INTRODUCTION TO THE DOSE METER
The Noise Dose Meter measure the frequency weighted noise exposures and peak
sound levels simultaneously.
The meter has the following features:
•Multiple simulated dosimeters (termed D1, D2 & D3)
•Simple operation, including direct read-out of results
•Ten built–in standard dose measurement setups:
OSHA-80, OSHA-90, MSHA-80, MSHA-90, DOD, ACGIH, ISO-85, ISO-90, NR-15
and NHO-01

•Pause function
•Nine user defined measurement setups
•30 dose (DATA) result stores
•Download of setups from PC to the meter
•Keypad lock protects meter against accidental operation
•Timers support pre–selection of measurement time and duration
•USB PC interface for the charging unit
The meter is ideal for quick on–site surveys and for monitoring personal noise
exposure in accordance with European ISO or USA OSHA, MSHA, DOD AND
ACGIH standards.
The meter is one measurement ranges: 70 – 140dB, A C & Z RMS weightings, A, C
& Z Peak weightings, Fast, Slow & Impulse time weightings, and energy exchange
rates (Q) of 3, 4, 5 & 6. In dose measurement mode, it display % dose, % dose
projected for an 8 hour period, peak level and measurement duration.
For countries that are subject to European Union regulations or the equivalent ISO
standards, the meter measure the daily sound exposure level (L
Aeq
,
8hr
, Pa
2
h
according to IEC 61252, which is identical with the L
EX,8h
required by ISO 1999),
while for USA OSHA/MSHA regulations they measure the Time Weighted Average
level (TWA).
When used as a sound level meter it display sound level, time-averaged (L
Aeq
) sound
level, peak and sound exposure level (SEL).

5-2 The Windscreen and Microphone
During use, it is essential that the meter is fitted with the Windscreen. The
Windscreen protects the microphone from potential erroneous results due to air
movement passing over it but also helps to protect from dust ingress, moisture or
minor impact damage.
To calibrate the meter it is necessary to remove the Windscreen to expose the
microphone. To unscrew the Windscreen by turning the black ring (not the foam!)
in a anticlockwise direction.
It will not normally be necessary to remove the Microphone but to do so unscrew
anticlockwise direction. When refitting the Microphone, screw the Microphone on
clockwise until it fits tightly.
Following calibration refit the Windscreen, screw the Windscreen in a clockwise
and take care do not over tighten; finger tight is sufficient.
