The Probe Check Feature
Designed to act as a measurement quality assurance tool, the Probe Check func-
tion in the Vectrino software lets you inspect the region where the Vectrino
makes its measurements by showing how the signal varies with range.
To start the probe check:
1
Make sure the probe is submerged in water.
2 Click Data collection > Start Probe Check. You can use it to diagnose and
correct problems and to optimize data collection.
The three coloured graphs correspond to each of the three vector receive beams.
Graphs are scaled in mm distance from the transmit trans ducer, parallel to the
transmit beam. One amplitude count corre sponds to 0.45 dB in signal strength.
The probe check function
shows how the signal varies
with range.
A is the transmit pulse.
B is the area around the
measurement volume.
C is a bottom echo.
A
B
C
The letters correspond to the following:
A
The transmit pulse.
B The part of the range, which contains the receive volume.
C The bottom echo.
The actual sensing volume is a relatively narrow region within the broad peak
indicated by
B.
