The view presented by the Matrix can be regarded as if the transducer was facing you. Instead of presenting the element data as a continuous vertical flow, all data received by each element are averaged and presented
as one block of information. Picture yourself looking "into" the transducer elements.
When you move the cursor over the matrix presentation of the transceiver channels, each element in the transducer can be clearly
identified as a rectangle. If you place the cursor on top of one of these rectangles, a small yellow tool-tip will identify key information.

This function is designed to check the operation of the individual channels in the transceiver, as well as the elements in
the transducer.
TipA rectangle with 32 black elements in the matrix view indicates a failure with a single transceiver board. The tooltip will indicate which board that fails. Restarting the ME70 system will normally fix the problem.
Failure of eight or nine consecutive transceiver boards indicates a problem with the power supply.

Weak signals indicate a problem with the +6 VDC supply voltage to the analogue amplifiers. |
|
• |
No response indicate a problem with the +12 VDC supply voltage to the digital circuitry. |
|

A failure in the +75 VDC supply voltage can only be detected in the transmit test. |
