 The sensor is connected to the MIQ/IDS module
(see section 3.7).
1. Install the sensor in a flow through armature and provide the sample flow.
or
For measurement and calibration in containers:
Prepare the sensor for measurement (see P
46).
Perform the following preparatory activities when you want to measure:
 Avoid gas bubbles (e.g. air bubbles) in the test sample.
 Use suitable vessels for measurement and calibration
(see operating manual of the VisoTurb
 Heed the minimum depth of immersion for the sensor
1.
Fill the test sample into a lightproof measuring beaker up to a level of at
least 6 cm.
2.
When immersing the sensor in the test sample, hold the sensor at an
angle.
