Diagnostics is used to test and debug the instrument and its
components.
Press to enter the diagnostic function
Curve
When the LCD displays menu number 3, press key to enter the
echo curve display function. Display in LCD is as follows.
To select other curves, press to enter the select curves menu.
Display in LCD is as follows.
Use key to move the arrow to the curve you want to display.
Press to confirm the selection.
EFF Curve:
The EFF curve show the final analyzed echo curve in logarithm units
Threshold setting is used to set the threshold size of the effective echo.
The larger the threshold setting is, the stronger the effective echo
amplitude is required, and the more favorable it is to eliminate small
signal clutter interference; But be careful: if the modified threshold value
is larger than the effective echo amplitude, it will cause the result of
misunderstanding echo. The default range of echo threshold is12DB
Echo Curve
The "Echo curve" shows the signal strength of the echoes over the
measuring range in dB. This curve is for engineering purposes only and
may be removed in future software versions.
