Warm Prompt :
1. Please don't use the meter under a high temperature and humid environment.
2. Please take out the batteries when not in use for a long time to avoid electrolyte leakage and damaging the meter.
3. When measuring the noise outside, please mount the wind-resistant ball on the head of the microphone from being directly blown by wind and measuring other noise.
