System description

The PCE-SC 09 sound level calibrator is a battery-powered wound source for direct and quick calibration of sound level meters and other systems for noise measurement. With adaptors, it can be placed on ½- and ¼-inch microphones. The calibration reference is 1000 Hz. This is the reference frequency for the internationally standardised evaluation curves. This means that with this calibrator you can calibrate sound level test equipment with A-, B-, C- or D weighting filters or with linear sound levels. The calibration pressure is 94 ±0.3 dB (1 Pa) and 114 ±0.3 dB (10 Pa).

Getting started

Power supply
Two 1.5 V AA batteries are required as power supply. Before replacing the batteries, switch off the meter. The battery compartment is located on the back of the device and is closed by a cover. Remove the cover, insert the batteries as marked and place the cover back on the battery compartment.

Preparation

To turn on the meter, press until the display shows a reaction. The meter directly starts with the sound output and displays the set sound level. To switch the sound level, press the key for the desired measurement range. To turn off the meter, press .

Operation

Preparation for calibration
First select the right aperture size for your sound level meter. As standard, 1/1-inch microphones can be inserted into the aperture. Use the included adaptor for 1/2 inch microphones. The adaptor can easily be inserted into the standard aperture. For a 1/4-inch microphone, use the optional adaptor.

Calibration
The calibration procedure for sound level meters within the measurement range of both calibration points is described below. For sound level meters within the measurement range of only one calibration point, you can perform only steps 1-3 with the respective sound level.

After turning on the calibrator, use the “94 dB” key to select the 94 dB sound level.
Carefully insert the microphone into the aperture of the calibrator as far as it will go. The sound level meter should be placed in the aperture horizontally so that the inner seal is as high as possible.
Wait a short moment for the sound level displayed on the meter to stabilise. Now you adjust the meter to the 94 dB sound level.
If the sound level meter has a measurement range of 114 dB, use the “ “key to select the sound level of 114 dB.
Compare the sound level displayed on the meter with the calibrator setting of 114 dB. If the reading is within tolerance, you can finish the calibration and carefully remove the meter from the calibrator. If the deviation is not acceptable, you must start again with step 1.

Effect of ambient temperature and pressure
In environments with normal atmospheric pressure, the influence is generally negligible. However, sound level calibrators including the PCE-SC 09 are dependent on changes in altitude. The diaphragm generates sound waves within the calibrator which have to work against the environmental air. When the air at higher altitudes becomes thinner and the atmospheric pressure decreases, the calibrator generates a lower sound level.
The PCE-SC 09 sound calibrator generates 0.1 dB less every 610 m above zero level. The effects of the temperature are less severe. The sound level calibrator has a temperature coefficient of 0 … 0.01 dB/°C.

Warranty

You can read our warranty terms in our General Business Terms which you can find here: https://www.pce-instruments.com/english/terms.

Disposal
For the disposal of batteries in the EU, the 2006/66/EC directive of the European Parliament applies. Due to the contained pollutants, batteries must not be disposed of as household waste. They must be given to collection points designed for that purpose.
In order to comply with the EU directive 2012/19/EU we take our devices back. We either re-use them or give them to a recycling company which disposes of the devices in line with law.

For countries outside the EU, batteries and devices should be disposed of in accordance with your local waste regulations.
If you have any questions, please contact PCE Instruments.
