4 Startup and use
4.1 Startup
4.1.1 Initial check
Connect the sensor to a PoE enabled network, and check that the instrument powers
up properly (see section 2.3). Use a web browser to open the instrument homepage
and check that the serial number of the instrument corresponds to that on the instru-
ment nameplate. In case you have difficulties connecting to the sensor, please see
section 2.3.1.
4.1.2 Calibration check
Wait until normal process conditions occur. The concentration reading is precalibrated
at delivery and a copy of the Sensor calibration certificate is shipped with the sensor.
If the diagnostic message is
NORMAL OPERATION
but the concentration reading does
not agree with the laboratory results, consult Section 5.2, “Calibrating the concentra-
tion measurement”.
4.2 Viewing sensor status
The basic information on the measurements is shown on the main page of the in-
strument (section 2.4.1). More information is shown on the Diagnostics page (sec-
tion 2.4.3).
The measurement result is calculated from the refractive index (n
D
) and process tem-
perature (T) values. Both of these values are available on the main page.
In addition to these measurements, the sensor monitors its internal temperature and
humidity, which both are available on the Diagnostics page. The internal temperature
should not be above 55 °C, and the humidity should be below 30 %.
