Precautions for use of pulse sound level meter and its calibration method
Impulse sound level meter is a general sound level meter for measuring exponential time weighted sound level. It is suitable for various industrial environmental noise measurement and environmental noise survey measurement. It is used for sound level measurement of environment, machinery, traffic, ships and other noises; it is applicable to industrial environmental protection, construction, sanitation, teaching and scientific research and other departments.
Precautions for the use of pulse sound level meters:
1. The microphone used in the instrument is a precision sensor, please do not collide with it to avoid damage to the diaphragm, and put it aside properly when not in use.
2. Pay attention to the polarity of the device battery or external power supply, and do not reverse the connection
3. When the instrument is not in use temporarily, the battery should be removed to avoid damage to the instrument due to leakage.
4. The instrument should avoid being placed in a place with high temperature, humidity, sewage, dust, air or chemical gas with high content of hydrochloric acid and alkali, and prevent direct sunlight.
5. Do not assemble the instrument without permission. If the instrument is not working properly, it can be sent to the repair unit or the factory for repair.
