3-10 DASH 2000 Patient Monitor Revision A
2000 412-001
2. Connect the BP simulator cable from the BLOOD PRESSURE 1 -
120/80 connector of the patient simulator to the BP connector of the
monitor.
3. Select ART as pressure site. Verify the ART parameter window,
waveform label, corresponding graticules, and waveform appear on
the monitor display, along with a BP waveform requiring zero
reference. If waveform does not appear select waveform display ART.
4. Press the FUNCTION push-button on the front panel of the monitor
to zero-reference the ART BP waveform.
5. Change the patient simulator BP output to 200 mmHg.
6. Observe a reading of 200/200 (200) ± 6 mmHg in the ART parameter
window on the monitor display.
7. Change the patient simulator BP output to WAVE (simulated BP
waveform).
8. Set the ART BP waveform gain on the monitor to auto.
9. Observe a distortion-free ART BP waveform and a reading of
approximately 120/80 (93) in the ART parameter window on the
monitor display.
10. Disconnect the BP simulator cable from the BP connector of the
monitor. This completes the BP test.
Pulse Oximetry Tests
1. Set the pulse oximetry (SpO
2
) simulator power switch to the off
position.
2. Connect the Nellcor-style SpO
2
simulator cable between the SpO
2
connector of the monitor and the SpO
2
simulator.
3. Set up the SpO
2
simulator as follows:
¥ SPO2 Ð 95.5% (using the white NELLCOR values),
¥ PULSE RATE Ð 100 B/M (beats per minute),
¥ MODE Ð NELLCOR,
¥ Power switch Ð on.
4. Verify a SPO
2
parameter window, waveform label and corresponding
graticules appear on the monitor display.
5. Verify the following appear on the monitor display:
¥ Sinusoidal SpO
2
waveform,
¥ SPO
2
% parameter reading of 92 Ð 99(%),
¥ PPR parameter reading of 96 Ð 104 (beats per minute).
