د کیسیلا CEL-246/K1 ډیجیټل لاګینګ د غږ کچې میټر ډول 2 کټ کارونکي لارښود ادغام

1. پیژندنه

This manual provides comprehensive instructions for the proper use, setup, operation, and maintenance of the Casella CEL-246/K1 Digital Logging Integrating Sound Level Meter Type 2 Kit. This device is designed for precise sound level measurements, incorporating Digital Signal Processing (DSP) technology for accurate and reliable data.

The CEL-246/K1 offers a wide measurement range, selectable frequency weightings (A and C), and time responses (Slow, Fast, Impulse). It features a non-decaying maximum hold function and a clear display showing current, highest, and average noise levels, along with a time history trend. Data logging capabilities are available via a USB output port.

۳. څه پکې شامل دي

The Casella CEL-246/K1 Kit includes the following components:

• One (1) Casella CEL-246/K1 Sound Level Meter

3. ترتیب کول

3.1 د بیټرۍ نصب کول

1. Locate the battery compartment on the rear of the sound level meter.
2. د کڅوړې پوښ خلاص کړئ.
3. درې (3) AA بیټرۍ دننه کړئ، د سم قطبیت ډاډ ترلاسه کړئ (+/-).
4. د بیټرۍ کمپارټ پوښ په خوندي ډول وتړئ.

3.2 Attaching the Foam Windscreen

Gently slide the foam windscreen over the microphone at the top of the sound level meter. This helps to reduce wind noise during outdoor measurements.

3.3 ابتدايي پاور آن

Press the power button to turn on the device. The display will illuminate, showing the current measurement mode and readings.

4. عملیاتي لارښوونې

4.1 بنسټیز عملیات

The CEL-246/K1 features simple two-button operation for ease of use. Refer to the on-screen prompts and the full user guide for detailed button functions.

4.2 Frequency Weighting

The meter supports two frequency weighting scales:

• الف- وزن: Attenuates lower frequencies to approximate the human ear's response, which is most sensitive between 3000 and 4000 Hz. Use for general noise measurements.
• د C- وزن: Reads all frequencies more uniformly, providing a better response to higher frequencies than A-weighting. Useful for pinpointing problems when A-weighted readings are very high.

4.3 Time Weighting

Selectable time responses include:

• ورو: Provides a slower response, suitable for measuring steady noise levels.
• روژه: Offers a quicker response, ideal for capturing fluctuating noise levels.
• انګیزه: Designed for very short, sharp noise events.

4.4 Maximum Hold Feature

The non-decaying maximum hold feature captures and displays the highest sound pressure level detected until manually reset. This is useful for identifying peak noise events.

4.5 Data Logging and USB Output

The meter includes a USB output port for simple data logging. Connect the device to a PC to download stored data or for real-time data analysis using the optional software package. Data can be exported in spreadsheet format for further analysis.

۶.۲ اتومات کیلیبریشن

The CEL-246/K1 supports auto calibration at a selected decibel level using the included acoustic calibrator. Refer to the full user guide for detailed calibration procedures to ensure measurement accuracy.

5. ساتنه

5.1 پاکول

Wipe the meter's exterior with a soft, dry cloth. Do not use abrasive cleaners or solvents. Ensure no moisture enters the device.

5.2 د بیټرۍ بدلول

Replace batteries when the low battery indicator appears on the display. Always use three (3) new AA batteries of the same type.

5.3 ذخیره کول

When not in use for extended periods, remove the batteries to prevent leakage. Store the meter in its carrying case in a cool, dry place, away from direct sunlight and extreme temperatures.

5.4 اندازه کول

Regular calibration is crucial for maintaining measurement accuracy. Use the provided acoustic calibrator according to the instructions in Section 4.6 and the full user guide. It is recommended to calibrate the device before each critical measurement session.

6. ستونزه حل کول

6.1 Meter Not Powering On

• Check if the batteries are correctly inserted with proper polarity.
• د تازه AA بیټرۍ سره بدل کړئ.
• ډاډ ترلاسه کړئ چې د بریښنا تڼۍ په ټینګه فشار شوی.

۷.۲ ناسم لوستل

• Perform an auto calibration using the acoustic calibrator.
• Ensure the foam windscreen is properly attached to minimize wind noise.
• Verify that the correct frequency (A or C) and time weighting (Slow, Fast, Impulse) are selected for your measurement environment.
• Check for any physical damage to the microphone or device.

6.3 Data Logging Issues

• Ensure the USB cable is securely connected to both the meter and the PC.
• Verify that the necessary software drivers are installed on your PC.
• Consult the software manual for specific data transfer instructions.
