5.CAUSE:
A malfunctioning voltmeter.
SOLUTION:
Check the system output voltage with a different voltmeter, or inject
a know voltage in the voltmeter in use to verify that it is operating
properly.
6.CAUSE:
Coarse linearity misadjusted.
SOLUTION:
Recalibrate the system.
7.CAUSE:
Beat note interference when using more than one sensor.
SOLUTION:
Ensure that the sensors are at least 3 diameters apart, or
Synchronize your sensor and electronics as described in
APPENDIX B.
8.CAUSE:
Ground loop.
This problem is usually the result of electrical ground surges from other
equipment.
SOLUTION:
1.In sensors with non-isolated coils (3U, 6U), isolate the sensors
from the ground.
2.Isolate the systems(s) from potential grounds so that the ground is
only through a desirable path.
