Data Output
8.
Connect DS-100A to sensor input of monitor and place sensor on
your finger.
4.
The monitor stabilizes on your physiological signal in about 10 to
15 seconds.
Verify saturation is normal (typically greater than 94 percent) and
pulse rate is about 72 (standard resting heart rate, but this value
varies widely between individuals) is correct.
The monitor can send data to a computer or to a printer using the RS-232
connection.
RS-232 Operation
To test RS-282 operation, connect the monitor to a suitable computer that has

up).
.
8. © Place ON/STDBY switch to ON.
4.
Connect a Nellcor pulse oximeter tester to oximetry sensor input of
monitor and verify following.
a.
The OXYGEN SATURATION and PULSE RATE displays each
indicate zero for a few seconds,
b.
The pulse bar begins to track artificial pulse signal from tester.
c.
After about 10 seconds monitor displays a saturation and pulse
rate within tolerances specified on tester.
&
The audio alarm may sound if tester is set to violate any of default
alarms.
e
You hear pulse beep and if monitor is in an alarm condition, beep
tone is indicated by a break in alarm tone.
