Overview.Overview.
Overview.
Thank you for purchasing the Model 14 sound level meter from Pulsar Instruments plc.
This entry level meter is designed to be quick and simple to use when taking basic
sound measurements and we are sure it will meet your requirements.
The Model 14 is a general purpose digital sound level meter which meets the full
requirements of IE 61672 to lass 2. The instrument has 'F' (Fast) response and has
both 'A' and ' ' frequency weightings. In addition facilities are provided to hold the
maximum reading occurring throughout the measurement period.
First time use.

First time use.
The Model 14 should be inspected for any signs of damage and also to ensure that all
relevant accessories are present. Your Model 14 will have been supplied either as a
single unit or as part of a full measurement kit, Model 14-K.

Before taking measurements, ensure the instrument has a new or highly charged
battery fitted. The instrument is supplied with a battery but it is not fitted for transit.
See page 9 for details of fitting and changing the battery.
Turn the instrument on by moving the OFF/F slide switch to the F position:
> OFF = Instrument is powered off.
> F = Fast Time Weighting
Allow the instrument to settle for 10 seconds before calibrating or taking
measurements.
Ensure the instrument is calibrated (see page 10 for details of calibration)
Select the required Frequency Weighting using the A/ slide switch:
> A = A-Weighting or dB(A)
> = -Weighting or dB( )
Select the most appropriate range for the acoustic environment using the H/L slide
switch:
> L = Low Range (suitable for levels up to 100dBA)
> H = High Range (suitable for levels over 65dBA)
If you need to capture the maximum noise level measured then press the MAX HOLD
button for at least ½ second.
Once released the text HOLD is illuminated in the top left of the instrument display. In
this mode the highest measured sound pressure level is displayed.
To turn off the maximum hold facility either press the MAX HOLD button again or turn
the unit off.
Fundamental precautions
Fundamental precautionsFundamental precautions
Fundamental precautions
This section contains some simple points that should be considered when using the
Model 14 instrument:
a) Allow the instrument to settle for 10 seconds after switching on before calibrating
or taking measurements.
b) Always check the battery before and after each measurement. The Model 14
monitors the battery continuously while operating.
c) Ensure that the white MAX HOLD function is turned off when not required. If this
is not done, the display will freeze the last reading and the word HOLD will be
displayed on the top left of the L D.

d) Wherever possible, always check the instrument calibration before and after each
measurement.
e) Whenever the instrument is not to be used for a long period of time (> one
month) then remove the battery completely. This action will prevent leakage
damage.

1. Ensure the instrument is turned off before removing the battery cover.
2. Remove the battery cover.
3. The battery is made accessible by pressing the left hand side of the battery
cover down slightly and then sliding it to the right. The spent battery can then be
removed and disposed of safely.
4. A new battery, IE 6F22 (NEDA 1604, PP3) can then be fitted. The battery can
only be fitted in one orientation.
5. Replace the battery cover by sliding it back into place from right to left.

Field Calibration
Field CalibrationField Calibration
Field Calibration
It is vital that the calibration of ANY sound level meter is checked before and after each
measurement. If this is done, it is reasonable to assume that the calibration during the
measurement was correct.
If this is NOT done, you will not subsequently be able to be certain that the instrument
calibration was correct and you can never be certain the sound level was as measured.
This process is commonly referred to as field calibration.
The sound level meter is calibrated acoustically using an external reference, e.g the
Sound Level alibrator Model 106, which is placed over the microphone. The calibrator
generates a stabilised Sound Pressure Level of 94dB (+- 0.3dB) at a frequency of 1kHz.
Calibration Procedure
Calibration ProcedureCalibration Procedure
Calibration Procedure
1. Ensure the battery is fitted correctly and has sufficient power left.
2. Ensure the microphone capsule is fitted correctly
3. Turn the instrument on with the following settings:
OFF/F in the F position
L/H in the L position
A/ in the A position
(This relates to Fast Time Weighting, Low Measurement Range and dB(A)
Frequency)
4. Ensure the MAX HOLD function is not active. (The word HOLD is not displayed
in the top left hand corner of the instrument display)
5. Attach the acoustic calibrator and turn it onto the 94dB output setting. An
acoustic calibrator such as the Model 106 is suitable.
6. Using the provided calibration screwdriver, slowly adjust the AL
potentiometer until the instrument display reads 93.7dB(A). (Turning the AL
potentiometer clockwise increases the displayed level whereas anti-clockwise
reduces the displayed level)
Note: Although the Model 106 Acoustic alibrator has an output of 94dB, the
pressure correction of the microphone capsule is 0.3dBA. For this reason the
Model 14 must be adjusted to give a reading of 93.7dBA.
7. The instrument is now calibrated.
For details of the operation of the Model 105 and Model 106 Acoustic alibrators, please
refer to the user manuals supplied with these units.
