Thoroughly clean the OTT ecoN; see Chapter 8.1.
Connect the OTT ecoN to the PC; see Chapter 6.1.
Fit a compatible VALtub on the OTT ecoN housing tube, see Figure 8.
Pour ultra pure water into the VALtub. The measuring windows must be com-
pletely under water.
Pour away the ultra pure water after approx. 10 minutes.
Pour fresh ultra pure water into the VALtub; the measuring windows must again
be completely under water. There may not be any air bubbles on the measur-
ing windows.
Call up the OTT ecoN web interface, see Chapter 6.2.
Perform a measurement: Call up the "Measurement" | "Parameter" | "Mea-
sure now!"
➝
the OTT ecoN starts a measurement and displays the result in the
browser window.
If the measured values are
lower
than
4.0 mg/L NO
3
-N with 1 mm path length
0.4 mg/L NO
3
-N with 10 mm path length
the zero point is OK!
If the values are
equal
to or
higher
than that figure, the OTT ecoN needs to be
recalibrated, see Chapter 8.3!
8.3 Calibrating the OTT ecoN
The nitrate sensor can be calibrated either in the factory by the OTT repair centre
or by trained specialist personnel with the appropriate equipment.
For calibration, directly contact the OTT Hydromet GmbH repair centre (see
