Signal Intensity
User can set the Signal Intensity of the LED (10-100%). The default values are based on the sensor selection
and the FlexSense and SafeTap body styles. If the user has a FiberSense the signal Intensity will likely need
to be turned down. Recommended Signal Intensity are shown in table below.
Pulse Length
This feature is only available in advanced mode. The Pulse Length should be left in Automatic unless
discussed with the factory. The Pulse length can be adjusted to increase measurement accuracies in specific
applications.

If
Auto Adjust
is chosen and the step-change is small, then the
Sample Rate
will normally be in
the fast,
Max Sample Rate
mode and will not be an advantage with regards to drift and sensor
lifetime.

Normal Sample Rate (2 to 3600s)
: Enter the Normal Sample Rate when process is at steady state.
This will be the longest interval between measurements.
Max Sample Rate (2 to 3600s)
: Enter Max Sample Rate when the process experiences a step
change. This will be the shortest interval to track a dynamic process change.
Change for Maximum Sample Rate
: Enter the desired magnitude of the step-change required to
trigger the Max Sample Rate (oxygen unit is dependent on Sensor Type and Settings).
Changes to
SIGNAL DATA
may affect the measurement performance and lifetime of the sensor.
Please consult the OXYvisor manual for a detailed explanation of when to change these
settings and what the recommended values would be for different cases.
If the OXYvisor is displaying a X22 error, “Signal intensity is too high” decrease the INTENSITY
(signal strength) until the error goes away immediately! Failure to do so will cause damage to
the sensor. Consult OXYvisor manual for further details and suggestions on properly setting
this parameter.
