calibration, and then exit the IBP PRESSURE CALIBRATE menu.
Set the BP value of the simulator respectively to 40mmHg, 100mmHg and
200mmHg. Then the screen of the PM-7000 should display 40±1mmHg,
100±2mmHg and 200±4mmHg.
Set the simulator output to ART wave. Then the screen of the PM-7000 should
display relevant waveform properly.
Unplug the IBP probe. Then the screen should prompt “IBP: Transducer 1 OFF!”
and “IBP: Transducer 2 OFF!”
Plug the OHMEDA cable to the IBP1 channel. Then the prompting message “IBP:
Transducer 1 OFF!” disappears.
IBP2 test:
②
Plug the IBP cable to the IBP2 channel, and repeat the procedure in Section .

1. Test fixture
Physiological signal simulator
2. Test procedure
Injectate and blood temperature test: Assemble the TB and TI test fixture, output
three TB temperature values: 36 , 37 and 38 . Then TB should be respectively
℃ ℃ ℃
36.0±0.1 , 37.0± ℃ 0.1 and 38.0±0.1 . Set the injectate switch to ON, output two ℃ ℃
TI temperature values: 0 and 2 . Then the screen should display 0±0.1 and
℃ ℃ ℃
2.0±0.1 .
℃
CO measurement: Set the CO.CONST and T
I
to the default values: 0.542 and 0 , ℃
set the injectate switch to OFF, and then press START. Then the simulator will
output 0 , 2.5L/M and 0 , 5L/M within 2s. The CO values should be 2.5±0.25L/M
℃ ℃
and 5±0.5L/M.

2. Test procedure
Mainstream CO
①
2
measurement: Set the calculation compensation of PM-7000 to
COMMON.
Plug the mainstream transducer to the CO
2
socket, connect the windpipe connector
with the CO
2
steel bottle, and open/close the valve of the CO
2
steel bottle based on
the interval of 3s. The CO
2
value should be the calibration gas pressure value:
76±5%mmHg. When the valve is opened permanently, the patient monitor prompts
“APNEA ALARM”.
Unplug the transducer. The patient monitor prompts “CO
2
transducer OFF” on
the main screen. Plug the transducer again. The patient monitor prompts “CO
2
transducer pre-heated”.
Sidestream CO
②
2
measurement: Set the calculation compensation of PM-7000 to
COMMON.
Plug the water trap to the water trap socket, connect the sampling tube with the CO
2
steel bottle, and open//close the valve of the CO
2
steel bottle based on the interval of
3s. The CO
2
value should be the calibration gas pressure value: 76±5%mmHg. When
