d.
Pulse waveform peak to peak (P-T-P) amplitude of approximately half-inch.
Actual amplitude may vary but will be a reference for low pulse amplitude/low
light patients.
7.
Press LIGHT LEVEL.
8.
Verify the increase LED lights. The pulse amplitude waveform initially flatlines and
then stabilizes at the same P-T-P amplitude of approximately half-inch.

Note:
Flat-lining is the only indication of a light change at the measurement site. If the
monitoring system recovers and displays normally, this is an indication of proper
operation with light changes.

a.
Active visual and audio alarms.
b.
Saturation indication between 73 and 77 inclusive.
c.
BPM indication between 57 and 63 inclusive.
d.
Pulse waveform of approximately half-inch P-T-P amplitude. Actual amplitude
may vary but references low pulse amplitude/
high light indications.
9.
Press PULSE RATE.
10.
Verify the 200 BPM LED lights. The monitoring system registers pulse rate increas-
es and stabilizes to a value between 194 to 206 BPM inclusive.
