7.5.9.1 Accuracy Test
The purpose of this test is to verify that the SpO2 Board performs accurately with any
selected SpO2 sensor. The test sends the infrared light output signal through both the red and
infrared channels. This produces a 1:1 ratio which corresponds to an SpO2 value of 85%.
The successful completion of this test signifies that the SpO2 Board can transmit and receive
light through the monitored sight, processing unit can successfully display the parameters. A
display of 85% means that the SpO2 Board can accurately display SpO2 over the entire
monitoring range.
a. Highlight the Accuracy Test from the SpO2 Diagnostic Menu and press the SELECT
key to start the test.

Shortly after the sensor is placed on a finger the SpO2 value is displayed along with
