Problem
Possible Cause Action
Measurement
appears to be false.
Sensor might be
damaged.
1. Check if the sensor or the sensor lid (e.g. broken
hinge) is damaged.
2. If the sensor is damaged, stop the measurement and
return the sensor for servicing.
If the problem persists, return the sensor for servicing*.
Sensor lid might not be
closed properly.
1. Check if the sensor lid is closed properly.
2. Close the lid.
If the problem persists, return the sensor for servicing*.
The application
parameters differ from
the ones the sensor was
adjusted and calibrated
for (i.e. tube size or
material, medium).
1. Check if the application parameters are the ones the
sensor was adjusted and calibrated for.
2. If necessary, exchange the tube for the right one.
If the problem persists, return the sensor for servicing*.
There is debris or dirt in
the flow channel.
1. Check if there is debris or dirt in the flow channel.
2. If necessary, clean the flow channel.
If the problem persists, return the sensor for servicing*.
There might be
electromagnetic fields
influencing the sensor.
1. Check if the sensor is connected properly to the
device and if the sensor is damaged.
2. Check if there are any electromagnetic fields or
disturbance sources that are not compliant with
standards that could influence the sensor or if the
sensor or its cable came into contact with an electric
cautery.
3. Remove the source of the electromagnetic field or
carry the measurement out somewhere else.
If the problem persists, return the sensor to em-tec GmbH
for recalibration*.
Wrong calibration table
selected.
1. Check if the selected calibration table is the one
appropriate for your application.
2. If necessary, select the right calibration table.
If the problem persists, return the sensor for servicing*.
