5.1 Measurement

To take a measurement, turn on the device by pressing the “On/Off” key. Once the device gets to the main screen, it measures the sound level continuously.

To select one of the available measuring ranges, press the “LEVEL” key. You can choose between the following options: Lo (30 … 80 dB), Med (50 … 100 dB), Hi (80 …130 dB), Auto

(automatic measuring range selection). Make your choice depending on the ambient sound level. If the ambient sound level falls below

the selected measuring range, the display shows “UNDER”. If the ambient sound level exceeds the selected measuring range, the display shows “OVER”.

To change the frequency weighing of the sound level measurements, press the “A/C” key. You

can switch between A-weighing and C-weighing.

To change the sampling rate, press the “FAST/SLOW” key. You can switch between “FAST” (1 measurement / 125 ms) and “SLOW” (1 measurement / 1 s).

6 Calibration

To perform a calibration, you need a suited sound level calibrator which has a ½ inch opening for microphones. To calibrate the device, follow these steps:

1. Adjust the device to the following settings: Frequency weighing: A Sampling rate: FAST Measuring range: 50 … 100 dB

2. Put the end of the microphone in the ½ inch opening of the calibrator. Make sure that the output signal of the calibrator lies within the set measuring range (for example 94 dB @ 1 kHz).

3. Turn on the calibrator and use the potentiometer on the side of the sound level meter to adjust the displayed value to the output signal of the calibrator (for example 94.0 dB).

The sound level meter comes with a factory calibration. We recommend calibrating it once a year.

8 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.
