Warm Prompt:
1.Do not use the meter in hot,humid environment.
2.If the meter is not to be used for a long time, remove the batteries to avoid electrolyte leakage damaging instrument.
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.
4. Normally you don't need to calibrate it because it was calibrated before delivery.If you want to calibrate it, it needs Primary standard acoustic source, acoustic environment,only the third testing organization or the credited laboratory could do it.
