W

 Warning 

The pulse oximeter component of the device is not intended to 
validate the SpO

2

 accuracy of pulse oximeter equipment. 

The pulse oximeter component of this device is not intended to 
confirm the SpO

2

 accuracy of the calibration curve of the pulse 

oximeter monitor or to assess the optical characteristics of 
representative pulse oximeter probes to determine their proper 
calibration. 

Not all functional testers and pulse oximeter equipment are 
compatible. Functional testers can vary in pulse methods, pulse 
contours, and amplitude. A functional tester might not 
accurately reproduce the calibration of the pulse oximeter 
equipment and can yield different results between pulse 
oximeter equipment. 

Note 

When the Type value is set to Masimo Rainbow, more SpO

2

 

parameters show on the display than other types of sensors. See 

Test a Masimo Rainbow SpO2

 to learn about these parameters. 

To set oximeter SpO

2

 optical emitter and detector parameters, push 

 to 

show the screen in Figure 44 on the display.
