How to use a digital noise meter better and more convenient
1. Read the instructions before use to understand the usage and precautions of the instrument.
2. Install the battery or external power supply to pay attention to the polarity, do not reverse the connection. Do not remove the battery for a long time to avoid leakage of the instrument.
3. Do not disassemble the microphone to prevent it from falling and put it properly when not in use.
4. The instrument should be kept away from high temperature, humidity, sewage, dust and air or chemical gas containing high levels of hydrochloric acid and alkali.
5. Do not disassemble the instrument without authorization. If the instrument is not normal, it can be sent to the repair unit or the factory for maintenance.
6, digital noise meter pay attention to waterproof, prevent high altitude fall.
Analysis and repair of common faults in digital noise meters
1, the display has no display
(1) The internal battery connection is disconnected or the battery contact is not good: solder the connection and replace the battery contact piece.
(2) Battery damage: Replace the battery.
2. The measurement reading is obviously low or less than 94.0dB when calibrated.
(1) The microphone sensitivity is too low or damaged: replace the microphone and recalibrate.
(2) The contact between the contact of the preamplifier and the microphone is not good: the contact is cleaned.
(3) The plug of the preamplifier is not in good contact with the host socket: replace the plug and socket.
3. The reading is high when the low sound level is measured, and the ground wire of the preamplifier is in poor contact: tighten the outer sleeve.Kassel brushless Servo Motor can be used in robotics, large-scale presses, forging equipment, food production, machinery and other industries.
