c. BPM indication between 57 and 63 inclusive.
d. Pulse waveform of approximately 1/2-inch P-T-P amplitude. Actual amplitude may
vary, but can be used as a reference for low pulse amplitude/low light patients.
11. Turn off the oximeter.
Light Level Test
1. With the oximeter turned off, connect the DOC-10 pulse oximetry cable to the
sensor port.
2. Connect the SRC-MAX tester to the other end of the DOC-10 cable.
3. Turn on the oximeter by pressing the ON/STANDBY button. Wait for the oximeter
to complete its self-check.
4. Select the PLETH view by pressing the following softkeys in sequence: SETUP,
VIEW, and then PLETH to view the pleth display.
a. Active audio alarm.
b. Flashing %SpO
c. BPM indication between 57 and 63 inclusive.
d. Pulse waveform of approximately 1/2-inch peak to peak (P-T-P) amplitude. Actual
amplitude may vary but will be a reference for low pulse amplitude/low light patients.
