Table 7 Troubleshooting the ATMOS 41W
Problem
Possible Solutions
ATMOS 41W not responding
Press the
TEST button (
) on to reset the ATMOS 41W.
Check device batteries. Replace alkaline batteries if close to 0%.
Recharge NiMH batteries if close to 0%.
Check for corrosion or water damage.
Check that the seals and gaskets are intact.
If the problem persists, contact
.
Water not flowing
through rain gauge
Check spring, downspout screen, and the outflow to ensure there is no
lodged debris.
If bird droppings are an issue a bird deterrent Kit made for the
ATMOS 41W can be added to the unit. Please contact Customer Support
for more information.
No wind speed
Check the anemometer pathway to make sure there is no debris
blocking the path of the sonic transducer measurement (between
transducers and convex base plate).
Check the sonic transducers for water build-up; if there is moisture,
take a dry cloth and dab it away.
Check to see that the convex base plate (
Figure 22
) is not dirty. Clean
by flushing with water and dry with a dry cloth (
Section 5.4)
.
Be sure the ATMOS 41W is level.
Not reading any precipitation
or not measuring
precipitation accurately
Remove any debris from the rain funnel. The ATMOS 41W must be
within approximately ±2 degrees of dead level (0, 0) in both the X and
Y directions to accurately measure rainfall. If not within this range,
drops from the flared hole can miss the gold electrodes entirely.
Use the internal level measurements that are available in the
ATMOS 41W data stream to confirm that the ATMOS 41W is level.
Gently twist the rain funnel and remove (
Section 3.2.2.1
and
Section 3.2.2.2
).
NOTE: BE CAREFUL TO UNPLUG THE PYRANOMETER CONNECTOR INSIDE THE
FUNNEL BEFORE DETACHING THE FUNNEL COMPLETELY.
Check to make sure that there are no obvious problems and that the
gold electrodes are aligned correctly (
Figure 35)
.
Check the tipping spoon is free of debris and swings easily under
light pressure (
Figure 14)
.
The accuracy of the rain gauge measurement can be checked
using the procedure described in
(https://meter.ly/41w-drip-count).
