3. ADJUSTMENTS
3-2
To measure the peak-to-peak voltage (Vpp), expand the waveform to 5
P
s/div. In
the example shown on the previous page, the amplitude is 220 Vpp.
Typical value of TX output (68 kHz)
Typical value of TX output (55 kHz)
3.2 Heading Alignment
1. Turn on the power. Locate a target (buoy, etc.) in the bow direction and display it
on the screen at a close range. The heading alignment is correct if the target in
the bow direction is displayed 12 o’clock on the screen. If it is not, go to step 2.

2. Read the skewed degree of the target selected at step 1.
3. Press the [MENU] key.
4. Use the [RANGE] control to choose [MENU MODE].
5. Use the [GAIN] control to choose SYSTEM to show the System menu.

6. Rotate the [RANGE] control to select HEADING ADJ.
7. Rotate the [GAIN] control to set value so a target directly ahead in bow direction
is displayed at 12 o’clock.

When the target on the screen is
skewed to the right, the transducer
heading is skewed to the left.
