Measurement / Operation

2.1 General information on the handling of the sensor cap
 Please do not touch the sensor membrane with your fingers unnecessarily
 Avoid any great mechanical stress of the sensor membrane (pressure,
scratches).
2.2 Commissioning
 D.O. sensor OPOX 11-3 with sensor cap
 Check and storage beaker
 Operating manual
1. Unscrew the protective hood from the sensor by hand.
2. Pull off the protective cap (red).
3. Put the protective hood on the sensor head and screw it tight by hand
as far as it will go.
The sensor is immediately ready to measure.
2.3 Measuring
Observe the required minimum immersion depth (see chapter 5 T
).
DATA
The OPOX 11-3 D.O. sensor enables precise measurements without any inci-
dent flow.
However, an incident flow of the sensor membrane improves the responding
behavior of the sensor (see chapter 5 T
be provided in different ways, e. g.:
 The flow of the water to be measured is sufficient (aeration tank, water pipe,
stream)
 Slowly pull the sensor through the water by hand (lake, container), or
 Use a flow aid such as a magnetic stirrer
2.4 Function check and user calibration
The OPOX 11-3 is factory calibrated. In the recommended application (see
page 5), the measuring characteristics of the sensor cap remain stable for the
specified service life. Thus, a user calibration is not usually required.
