FIGURE 8-1. Internal components
OBS-5+ or pressure sensor malfunction.
•
Open unit and inspect for: 1) broken sensor wires, and 2) loose pressure
sensor connector (FIGURE 8-1).
•
Check sensor power by clicking
Survey
and selecting all sensors; the
green LEDs should illuminate. If they do not, the sensor power circuit
may not be working.
•
If the depth sensor reads high and does not change, it may need to be
cleaned (see Section 9.2,
Pressure Sensor)
.
•
If the sensors appear to be in working order, the digitizer or
microcontroller may be damaged. Such problems require factory service.
