Operating a spotWave Device
Only operate a spotWave device if it has been properly installed.
16.1.
Connecting an AE Sensor
Only connect passive AE sensors (without integrated preamplifier) to the input socket of a spotWave device. It
is recommended to use AE sensors from Vallen Systeme GmbH.
Use a cable that is not defective and in good shape. The length of the cable influences the electrical signal
attenuation. The standard length of the sensor-to-device cable is 1.2 m. Only use longer cables if the impact
on the signal attenuation is known.
NOTICE
Damaging Electronic Components
Feeding in energy outside the specified range will damage the electronics.
Risk
Feeding in high current will lead to blown fuses and possible damaged electronic components leaving the
device inoperable.
How to Avoid the Risk of Damaging Electronic Components
Before connecting a cable to the SMA input sockets of the device, make sure that the external source is within
specified limits.
16.2.
Connecting a Coupling Check Transducer
Only connect a device from Vallen Systeme that is labelled and specified as Coupling Check Transducer
(CCT).
For connecting the CC-transducer to the spotWave device use the appropriate cable (product code: CBL-1-
1M2-V70).
16.3.
Operation Modes
A spotWave device can be operated in two modes (i) acquisition mode and (ii) logging mode.
16.3.1. Acquisition Mode
In Acquisition Mode the spotWave device is permanently connected to an end device. The end device is
running the Acquisition software which writes the measurement data to the storage medium of the end device.
In this operating mode the spotWave device is powered by the end device.
16.3.2. Logging Mode
In Logging Mode, the spotWave device is not connected to an end device. It writes the measurement data to
its internal storage medium. In this operating mode the spotWave device has to be powered by an external
battery pack.
The Logging Mode is configured by the use of the Acquisition software. For configuration purposes the
spotWave device needs to be connected to an end device. Upon disconnecting the spotWave from the end
device it loses power. The real time clock information can be retained in the internal memory for 60 minutes
