Damaged sensor or 6200 DCP
input channel. Check sensor cable/connector pin
A to B, it should read 10K ohms,
A to C or C to B will vary
between 0 and 10 kohms, as vane
is rotated. Check manufacture
service manual for more
information.
If potentiometer is damaged
return unit to factory. 5.2 No wind direction
or noisy output
indicated.
Note: There is no
wind direction
without wind speed
first.
Note: The 6200
DCP does not
average readings.
It will take a
reading according
to the time stamp
on the data.
Sensor potentiometer and
wiper is within specification. Check MET connector pin A for
excitation voltage.
If excitation voltage is not present
return unit to factory.
If excitation voltage is present,
jump A to B, reading should be
full scale (360 degrees), then
jump C to B, reading should be 0
degrees. If these readings are
true, then the problem points to
the wind speed sensor. 5.2
Damaged sensor or 6200 DCP
input channel Check MET connector pin G for
excitation voltage, 2.5 volts DC
pulses.
If excitation voltage is present,
jump F to G, reading should be
full scale (1.0 units), then jump F
to M for minimum range scale (0)
If excitation voltage is not present
return unit to factory 5.2 No air temperature
Displayed
If excitation voltage is present,
but still no temperature data Replace temperature /RH module
Check manufacturers replacement
instruction and Met5 suite
disassembly. 5.2
Damaged sensor or 6200 DCP
input channel Check MET connector pin K for
excitation voltage.
If excitation voltage is present,
jump K to J, the reading should
be full scale (100RH units), then
jump J to H for minimum range.
If the excitation voltage is not
present return unit to the factory. 5.2 No RH data
displayed
If excitation voltage is present,
but no temperature data Replace temperature /RH module.
Same procedure as with the air
temperature sensor. 5.2
