Recommended sampling interval: 1 minute (with simultaneous sampling of the
precipitation intensity)
R
ecommended storing interval: Any time between 1 minute and 24 hours. The
datalogger must total the individual measured
values using a summing function over the com-
plete storing interval!
Note: Every interface polling resets the total amount values in the OTT Pluvio

Accu NRT
This measured value outputs the sum of the correct amounts of precipitation over
the sampling interval with a fixed output delay of 5 minutes. Due to better filter-
ing, this valuable provides a more precise precipitation sum. Fine precipitation is
col lected over a maximum of one hour and output after reaching the threshold. If
the fine precipitation does not reach the threshold within an hour, there will be no
output. This value is particularly suited for daily and monthly totals
Output delay: Non-real-time output (NRT)
Units: mm · inch
Threshold: 0.03 mm within an hour
Recommended sampling interval: 1 minute (with simultaneous sampling of the
precipitation intensity)

to zero. The 5 minute output delay provides the option for climatological databases
to apply a timestamp correction when necessary.

Accu total NRT
This measured value outputs the sum of the correct amounts of precipitation since
the last device start with a fixed output delay of 5 minutes. For this purpose, the
individual Accu NRT values are totalled (redundant sensor). This value is particularly
suited for daily or monthly totals as well as for tracking the plausibility of the Accu
NRT and Accu RT-NRT values. Benefit: No loss of the collected precipitation
amount values in case of temporarily disrupted data transfer.
Resetting this value is achieved
– by a separate SDI-12 reset command, or
– by switching the power supply on/off, or
– automatically if the measurement range (500 mm; 50 inch) is exceeded
Output delay: Non-real-time output (NRT)
Units: mm · inch
Threshold: 0.03 mm within an hour
Recommended sampling interval: 1 minute (with simultaneous sampling of the
precipitation intensity)
Recommended storing interval: Any time between 1 minute and 24 hours
(do not total/average measured values)
