No/low precipitation output
䊳
No precipitation output
– when USB interface is/was connected,
– after emptying,
– start-up/power failure:
➝ wait for 5 minutes.
䊳
Collecting bucket overflow:
➝
empty the collecting bucket.
䊳
Evaporation rate is very high (collecting bucket is empty and ambient
t
emperature is high):
➝
add approx. 1 to 2 litres of water to the collecting bucket.
䊳
Apparently low output for NRT values:
➝ wait for 5 minutes (delay caused by filter algorithm).
䊳
Increase in weight > approx. 12 mm within 6 seconds:
➝ no precipitation output (filter algorithm detects foreign matter), since amount
of natural precipitation is exceeded; check precipitation gauge status:
Warning “+16” (using the OTT Pluvio² Operating Software).
䊳
Precipitation gauge probably failed:
➝ perform Guided Accuracy Test (using the OTT Pluvio² Operating Software).
䊳
Precipitation gauge is not level:
➝ check the bubble level indicator and correct adjustment as necessary.
Note: Check whether measured value used is suited for present application
(behaviour over time: Real-time output (RT), Non Real-time output (NRT), or
combination value (RT-NRT))! For a description of the individual measured values,
refer to Chapter 3.1. Use another measured value as necessary.
Incorrect precipitation output
䊳
Foreign matter (leafs, insects, …) have entered the collecting bucket (increase in
weight < approx. 12 mm within 6 seconds; any higher increase is detected as
foreign matter by the filter algorithm):
➝ manually correct the amount of precipitation by deducting a respective
amount.
䊳
Base plate is incorrectly levelled:
➝ Rotate the base plate so that the connector block of the orifice rim heater
is facing in South direction (North direction on the southern hemisphere)!
Refer to Chapter 5.6.
䊳
Anti-freeze agent without water was added (hygroscopic behaviour):
➝ Add anti-freeze agent only as an aqueous solution (add 40 % of water)!
