The noise levels recorded are displayed on the Correlator. The closer a measuring point is to the leak, the louder the recorded sound.
Pinpointing Procedure Proceed as follows: Step Description 1 In the main menu, tap the button . 2 In the displayed menu, tap the Tools button. 3 In the displayed menu, tap the Pinpointing button. 4 In the displayed menu, tap the upper button. Result: The Audio menu for ground microphone use opens. 5 Adjust the microphone gain for the pinpoint location using the slider at the top left of the screen. slide to the left ... to reduce the gain slide to the right ...
Pinpointing Step Description 7 In the displayed menu, tap the Start Pinpointing button. Result: The following menu opens: 8 Go to the first measuring position and put the microphone on the ground. 9 Tap the Start button. Result: The measurement starts. The Current value and the Minimum value of the measurement are displayed. Instantaneous value (Current value) Minimum value (quietest recording of measurement) The bar's height represents the noise level.
Pinpointing View Up to 10 measurement results can be displayed side by side. If more than 10 measurements are performed, always the oldest result (displayed on the very left) is dropped out of the row in favor of the new result. Ideally, the minimum value increases with every measurement as long as you move toward the leak. The minimum value decreases again after you have passed the leak position. The drop symbol identifies the measurement with the highest minimum value.
Pinpointing 16.3 Pinpointing using Multi sensors In the area of the pre-located leak position, up to 8 sensors are placed on the ground along the pipe. The devices record ground noise and send data to the Correlator. Multi sensors as well as Power transmitters can be used. Requirements The following requirements must be met: • All sensors to be used must be registered in the Correlator's Multi sensor pool (also called "Offline pool" (see page 55)).
Pinpointing Procedure Proceed as follows: Step Description 1 In the main menu, tap the button . 2 In the displayed menu, tap the Tools button. 3 In the displayed menu, tap the Pinpointing button. 4 In the displayed menu, tap the lower button. 4 In the displayed menu, select the sensors that shall be used. Tap the appropriate field to enable/disable the checkbox. Only "enabled" sensors will be part of the measurement. 5 Tap the Start pinpointing button.
Pinpointing View On the screen, up to 8 Multi sensor graphics are shown which represent the sensors in use. Inside the graphics, the measured values of the respective sensor are shown. The order of the sensors on the screen does not reflect the actual position of the sensors on site. The order on the screen is based on the sensor numbers (1-8 and A/B).
