- Records sound level, vibration level or DC voltage. External control is possible for pen, paper feed and marker functions. Operates in sync with level processing equipment.
- Records sound or vibration levels
- Records DC voltages
- External control of pen, paper feed, and marker functions
- Measurement with coordinated paper feed
- Operates in sync with level processing equipment
- When the measured sound or vibration level exceeds a certain threshold, paper feed can be automatically increased for easier reading of the recorded information.
- This saves paper and is useful for example in train and airplane noise measurements or other situations where non-continuous events are to be recorded.
