Testing the receiver and transmitter channels with the BITE B-Scan page
The B-Scan page allows you to monitor the time series of data that is received from each of the elements in the MS70 transducer. The start sample and the number of samples to be displayed are adjustable.
Prerequisites
The MS70 is switched on and working in normal operational mode. Neither tools nor instruments are required.
Context
When you move the cursor over the B-Scan presentation of the MS70 transceiver channels, each element in the transducer is clearly identified as a long coloured vertical rectangle. If you place the cursor on top of one of these B-Scan rectangles, a small yellow tool-tip will identify key information.
•  The identification of the transducer element
•  The identification of the transceiver board
•  The current sample you are looking at
•  The measured echo value (in dB)
The following requirements must be met:
•  The information presented by the B-Scan page verifies that the MS70 is fully operational.
•  All elements are operational in both transmit and receive.
Procedure
1 On the Main menu, set Beam Mode to Example 1 Sector Uniform Weighting.
2 Select the Operation icon.
The icon is located under the Main menu. It is used to open the Operation menu. Choose these settings:
a Set Operation to Normal.
b Set Range to: 100 m.
c Set Ping to On.
d Set Ping Mode to Interval.
e Set Ping Interval to 1 s.
f Set TX Mode to Active
g Set TX Power to Maximum.
3 Start the BITE (Built-In Test Equipment) utility.
4 Select the B-Scan tab to open the page.
5 Choose these settings:
a Select Element amplitude.
b Set Start sample to 0.
c Set Sample range to 1000.
d Set Decimation Method to Peak.
e Set Scale to Automatic.
f Set the Sample Pixel Size to fit your preferences.
6 Check that the channels are uniform.
7 Check for any weak elements in the transmission sample range.
If any weak elements are detected, record these in the result table.
8 Check for any black lines in the transmission and reception sample ranges.
A black line would indicate an unserviceable element. If any such elements are detected, record these in the result table.
