How to Use the Benetech GM1356 Sound Level Meter

Alright, now that we've covered what the Benetech GM1356 is, let's talk about how to use it. It's really quite straightforward, but following the correct steps ensures accurate and reliable readings. First, install the batteries correctly. Make sure you have fresh batteries inserted into the device. Most models require standard AAA batteries. Next, power on the device using the power button. You should see the LCD screen light up. Now, select the appropriate measurement range and weighting, usually with buttons on the device. For most general purposes, the A-weighting is the default and often the best choice, but C-weighting can be used for more specific applications. Position the microphone of the GM1356 in the area where you want to measure the sound. Hold the device at arm's length to minimize the impact of your body on the readings. Make sure there are no obstructions between the sound source and the microphone. Read the sound level on the LCD screen. You can use the data hold function to freeze the reading if needed. Finally, once you are done, power off the device to save battery life.

Calibration and Accuracy

To ensure the Benetech GM1356 gives accurate readings, it’s a good idea to calibrate it periodically. Calibration involves using a sound calibrator, a device that produces a known sound level, to check if the meter reads correctly. Insert the microphone of the sound level meter into the sound calibrator. Adjust the calibration control on the meter until it displays the sound level generated by the calibrator. If you don't have a calibrator, you can compare the reading with another calibrated sound level meter or take multiple readings in the same environment. Always store the sound level meter in a clean, dry place when not in use. Regular maintenance and proper handling will extend the life and accuracy of your device. Always be mindful of the meter’s specifications and limitations to achieve precise sound measurements.
