Operation
Overview
This chapter describes a few of the most common functions used
during normal operation.
Selecting operational mode
You are now ready to start the actual operation of the ES60 echo
sounder. The first thing to do is to choose operational mode.
Open the File menu, choose Operation to open the Operation
dialogue box. In the Mode group, click Normal for normal
mode.
(You may alternatively click Replay for replay mode, but you
must then also click Files to choose a replay file. Note that
operating in replay mode will restrict you from changing certain
parameters during operation.)
Next, you need to define the ping rate. To do this, locate the
Ping Rate group box, and set the ping rate to Interval for
manual setting of the ping interval. For this exercise, set the
ping interval time to 1 second, and click OK to finish.
The echo sounder will now start pinging, and after a few
moments the echogram field on the display will present a new
echo line. The various fields on the display are explained in
detail in the Display views chapter.
Transceiver settings
The operational mode and the transceiver frequency are
displayed to the far left in the Header view. A dedicated
dialogue box - Transceiver Settings -isusedtodefinevarious
parameters associated with the transceiver. These settings
include transceiver mode, the depth of the transducer surface,
the transmit power, and the pulse length.
To open this dialogue box, position the cursor over the mode
and frequency information in the Header view, and click the
right
mouse button. Specify the estimated depth of the
transducer surface, and set Transmit Power to its maximum
value. Set the Pulse Length to a medium value of 1.024 ms (for
38 kHz), and click OK to accept the settings.
The chosen pulse length will result in an acceptable resolution
of approximately 0.75 m, and acceptable signal-to-noise ratios at
the depths considered in this example.
