Offline correlation (Multipoint measurement)

9 Offline correlation (Multipoint measurement)
A group of 2 to 8 sensors is programmed for measurement and then deployed at the
measuring points. Multi sensors and/or Power transmitters can be used. The
measurement is carried out by all sensors simultaneously. During the measurement,
there is no contact between the sensors or between the sensors and the Correlator.
After the measurement, the sensors are collected and the recorded data is read, then
correlations can be carried out and displayed on the Correlator.
The following requirements must be met or preparations must be made:
• A digital or printed pipe network plan of the relevant measuring area with all pipe
parameters is needed.
• The batteries of the devices involved must be charged.
• All sensors involved must be registered in the Correlator's Multisensor pool (also
called "Offline pool" (see page 55))
• If Power transmitters will be used: The microphones must be properly connected.
• All sensors must be received by the Correlator. (This is the case, when each battery
icon in the Correlator's Start menu shows the battery level of the relevant sensor. If
a question mark is shown, the corresponding sensor cannot be reached.)
Configure the sensors for the measurement:
Step Description
1
All sensors must be turned on.
2
In the Correlator's Start menu, select the required Offline measuring mode
("COR MS-3 with microphone" or "COR MS-3 with hydrophone").
Use the arrow buttons to choose the mode, then tap the large central button to
open it up.
