Reviewing Optical Sensor Performance
From the maintenance screen, press the “Optical Sensor Performance” menu. This menu displays readings
and data relevant to the performance of the pressure guidewire currently being used. If no wire is plugged
into the OpM3, if the pressure guidewire is malfunctioning, or if it is not correctly plugged into the OpM3,
then no data will appear on this screen. Once a functioning pressure wire is connected to the OpM3
system, this screen will populate with live data relating to the performance of the wire (image below).
This screen displays the guidewire’s Serial Number, probe value in nanometers, plus the actual value in
nanometers read by the Optical Unit and the difference between the two (Delta).
It is also possible to plug a Reference probe or a Reference Gauge factor to obtain reference values. If the
pressure guidewire presents poor signal values, it may need replacing. If the replacement wire also
presents poor signal values, contact authorized field service person and/or OpSens.
