Testing The Transmitter Channels With The Bite Matrix Functionality - Simrad ME70 Instruction Manual

6 Locate any elements that exceeds the requirement for difference between neighbouring
elements.
Record the noisy elements in the result table. The difference between neighbouring
elements may be large due to noise in the test basin. Noisy elements on the side of
the transducer must therefore be ignored.
7 Evaluate the level for the functional elements by pointing at each element and read the
level from the tool tip. Check for neighbouring elements with the maximum deviation.

for testing the transmitter and receiver circuitry. The presentation is provided on a matrix
corresponding to the element locations in the transducer. For transmitter testing, the ME70
must be operational, and both operational and BITE parameters must be known.
Prerequisites
The ME70 has been set up with its hardware units connected as specified in the ME70
Installation manual.
• If applicable: The transducer is replaced with a dummyload.
• The ME70 system is turned on and operates normally.
