PT0 - Help
The PT0 command displays the test menu (shown below). As implied by the NOTE, adding 100 to the test
number repeats the test continually until the Pathfinder receives a <BREAK>. Sending PT200 runs the
PT3 and PT5 tests. PT300 runs the PT3 and PT5 tests continually until the Pathfinder receives a
<BREAK>.
Example:

Built In Tests

PT0 = Help
PT3 = Receive Path Test
PT5 = Transmit/Receive Loop Test
PT9 = Transmit Memory Test
PT10 = Receive Memory Test
PT11 = FRAM Test
PT12 = RAM Test
PT13 = ROM Test
PT14 = Recorder Test
PT19 = Ringing Test
PT3 – Receive Test
This test displays receive path characteristics. This test must be done with the transducer in water.
Submerge the transducer face in a few inches of water when running the PT3 test.
The test
may fail in air and if so, is not relevant.
Only a failure with the transducer at a minimum in
contact with water is a relevant test.
