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.
5. Press the SRC-MAX MODULATION selection button. The SRC-MAX
MODULATION LED lights. The oximeter pulse amplitude waveform initially
increases in amplitude and then stabilize at P-T-P amplitude of approximately 1-
inch.
