9.1 Maintenance
To ensure reliable and accurate measurements, Campbell Scientific recommends doing the
following every month:
1. Check the integrity of the cable and data logger connections. Replace cable if damaged.
2. Inspect the funnel for any damage or blockage. To clear a blockage, detach the funnel from
the base, remove debris, then reattach the funnel.
3. Check and clean the filters (see the following section).
4. Level the RainVUE-series if necessary (see
aXWTILT!
and
aXRTILT!
commands in
[p. 18]). The RainVUE 10 has a bubble level next to a leveling foot; the RainVUE 20
bubble level is visible after removing the funnel.
5. Clean dirt from the tipping bucket. Avoid tipping the bucket if the RainVUE-series is still
connected to the data logger.
6. If the data logger is disconnected, check the tipping mechanism for stiffness.
a. Try to balance the bucket in its center position. It should be extremely difficult or
impossible to balance.
b. If the bucket balances easily, closely examine the tipping bucket assembly for dirt or
wear on the pivot pin and bucket tubs.
9.1.1 Cleaning and replacing filters
The RainVUE-series has both a funnel filter and a stainless-steel, mesh screen filter (see the
following figures). The mesh screen should be regularly cleaned. Both filters can be replaced if
damaged or lost.
