200ms but must be set to 100ms
SOVT 29 RB-S When the PG-500 is powered on what lights are illuminated:
The only lights that should be lit are the AUTO, TRUE and CALB lights to indicate the 100ms setting is selected.
The LED on top of the DFF1 lights or flashes according to equipment state, as described in the table:
SOVT 29 RB-S Radar Main Bang should be set to:
Change the Range in the drop‐down box to .125nm.
Press the (ADJ) key for more than 2 seconds. All LED’S go off.
Within 10 seconds, set the difference between sensor heading and actual heading with the DAMP key for (+) or ADJ key for (‐). For example, the heading output by the PG‐500 is 70° and the actual heading is 75°. Therefore, the difference is +5°. Press the DAMP (+) key five times to set +5°. Each time the DAMP (+) key is pressed the LED’S light as shown in the Heading Alignment Graphic on the right.
A high frequency pulse is able to detect objects in the water at much higher detail and within a narrower beam angle, but at shallower depths. The beam angle is the angle at which the pulse spreads out laterally as it travels through the water. A low frequency pulse has less “resolution” of objects in the water, but operates at a wider beam angle and can penetrate farther in the water to a greater depth. High frequency typically results in a beam angle of 12 degrees, and is limited to a maximum useful depth of _______. Low frequency results in a beam angle of 45 degrees and can operate at depths of up to ___________.
400 – 700 feet.
800 – 1200 feet
The best way to determine the status of the depth sounder is to have the ________ selected as an active display either on the forward or aft MFD.
