This chapter describes common problems, their probable
causes and remedies, and contact information.
Table 4 Some Common Problems and their
Remedies
Probable Cause
The sensor is mechanically
damaged.
After removing the connector's
hexagon nut, the connector is
bent, which breaks the
connection wires.
The sensor is not powered
properly.
Some Vaisala products, for
example, WAT12, switch
power on to the sensor only
for a very short period (200 µs
to 500 µs).
Remedy
Check the cables and
connectors.
Check the connector.
Check that the supply voltage
is from 9.5 to15.5 VDC
Check that the sensor output
rises above (U in - 1.5 V) at the
end of the power pulse.
