11 Real-time measurement
With a single sensor, you can perform a real-time measurement. By this means, you get
an idea about the current noise situation in the pipe.
The real-time measurement can be performed with a Power transmitter or with a
Multi sensor.
At the desired location, the sensor is attached to the pipe. Then, via the Correlator a
noise measurement is started. The measurement data are transferred from the sensor
to the Correlator and displayed there in real-time.
If a Power transmitter is used, you have the chance to listen to the recorded noise "live"
via headphones.
The following requirements must be met:
• The relevant Power transmitter or Multi sensor must be registered to the Correlator.
• The battery level of the sensor must be OK.
(Power transmitter: LED bar must show at least 2 green lights
Multi sensor: status LED must show green or yellow light)
• The measuring point must be in the Correlator's radio range (max. 5 m).
• If a Power transmitter will be used: Antenna and microphone must be properly
connected.
Switch the Power transmitter or Multi sensor on and attach the sensor to the pipe.
Subsequently, proceed as follows:
