Use the hospital evacuation system with the service gas-evacuator tee. If
hospital evacuation system is not available, perform service in a
well-ventilated area.
Every 12 months, perform flowmeter verification on O2 only at the following flows: 500 ml/min,
1L/min, and 5 L/min.
Use the N2O Flow Control Valve and perform the tests in Table A progressively from low to
high flows. Do not overshoot any setting. Allow the System O2 monitor to stabilize between
readings.

Calibration Procedure
NOTE:
1.
2.
The monitor should be on 5 minutes prior to calibration. First "CO2 balance N2" is
used to check CO2 span. Then, CO2 with N2O is used to check N2O span and CO2
compensation. Verify that the cal gas has not expired.
Zero Calibration
a. Verify monitor is in Low Flow.
b. With the full length of sample tubing connected to the monitor allow room air to be drawn
into the monitor (Ensure the room air is free of appreciable levels of nitrous oxide and
carbon dioxide).
c. If required, adjust the N2O Zero and the CO2 Zero controls until the upper display
indicates 0% (N2O) and 0.0% (CO2).
CO2 Calibration Only
a. Connect the free end of the sample tube to the 5% CO2 balance N2 cal gas can.
Do not block off the open end of the adapter tube. The opening is required to bleed off
excess pressure in the line.
b. Press down continuously on the valve stem of the gas canister. When the readings are
stable, adjust the front panel CO2 Span control until the reading matches the value of the
CO2 calibration gas (5% ±0.1).
NOTE:
3.
F.
To ensure the calibration can is providing a sufficient flow of calibration gas to
the monitor, continue to press down on the valve stem for five additional
seconds and verify the readings remain stable. If the readings steadily
decrease, an insufficient volume of calibration gas is indicated (depleted
canister). Using a new can of calibration gas, repeat the Calibration procedure.
CO2 and N2O Calibration
a. Connect the CO2 / N2O calibration gas (65% N2O, 5% CO2, 30% O2) canister.
b. Press down continuously on the valve stem of the gas canister. When the readings are
stable, adjust the N2O Span control until the reading matches the value of the N2O
calibration gas (65 ± 1%). Note the reading of the CO2 measurement. It should be
5 ± 0.1%. If not, adjustment of the CO2 compensation is required.
c. Disconnect the gas canister from the sample tube and allow the readings to return to
zero.
d. If either reading does not return to zero, repeat steps 1 - 3.

Do not touch the sample line to your mouth or face. When breathing into
the sample line, hold it two to three inches away.

Set the high End tidal and Low End Tidal alarm values to trip these alarms.
Verify the audio and visual alarm indicators are activated for each of these alarms.
Clear the alarms and set the Apnea Delay switch to 30 seconds.

NOTE:
B.
C.
Verify that the probe connection and input and output jacks are in good condition.
Replace the battery every 48 months. Record the replacement date on the battery.
Later revisions of software refer to SpO2 instead of SaO2. For testing purposes, they
are the same.
DIAGNOSTIC/CAL TESTS - ANNUAL ONLY
1.
2.
3.
Turn the Modulus II Plus System Master Switch to the OFF position.
Set the oximeter to run on battery power.
Enter the service mode by holding down the Alarm Volume button and turning the power ON.
Follow the instruction on the display to perform the diagnostic and calibration tests.
OPERATIONAL AND ALARM TESTS
1.
Turn the oximeter ON.
a. Verify that the Graphics Display indicates "Ohmeda-Biox 3700/3710/3700e Revision: X
and the digital display shows all eights, and then goes blank.
b. Verify the unit beeps two to three times and alarm indicator flashes twice.
2.
Place a probe on your finger or ear (if ear probe). After the system check, verify that there
is a good waveform displayed and that the SaO2 and Pulse Rate numbers are displayed.
3.
Hold the "Waveform" key down for approximately 3 seconds. Verify that the message
"FAST RESPONSE SELECTED" is momentarily displayed and that an "F" appears on the
waveform display. Hold the "Waveform" key down again for approximately 3 seconds and
verify that the message "SLOW RESPONSE SELECTED" is displayed momentarily and
that the letter "S" appears on the waveform display.
4.
Verify that a pulse beep sounds once with each plethysmographic (SpO2) pulse displayed on
the waveform display.
NOTE:
5.
MP 1014
Number: 3.00
Proceed with audio alarm testing only after the initial two minute alarm silence
period is over (Rev P and Later Software). The Alarm Silence Period for Rev M
software is 1 minute after power up.
Verify the Patient Alarms are functional.
a. Set the high and low SaO2 and Pulse Rate Alarm limits beyond the readings. Ensure
that the alarm tone sounds and the violated alarm limit and reading flashes on the Digital
Display.
b. Verify that the ALARM SILENCE control temporarily silences all audible alarms for 2
minutes (30 secs for Rev. M) and changes the flashing LED alarm light to a steady red
light.
c. Turn the oximeter OFF.

NOTE:
Annual Monitor Calibration
1.
Calibration/ Overpressure Check
a. Enter the calibration mode by holding down the Start button and turning the power ON.
Press the Period up arrow button to enter the Calibration Mode 01.
Verify a beep tone and that the display shows calibration set up.
b. With "Sense" input port open, adjust R56 on the main board for "6" ± 3 (DC offset) on
the Systolic display.
c. Verify "80" ±6 (Adult AC offset) in the Diastolic display. Adjust R54 as necessary.
d. Verify "80" ±10 (Neonatal AC offset) in the Rate display. Adjust R53 as necessary.
e. Verify "80" ±10 (Pleth AC offset) in the Mean display.
f. Disconnect the double lumen hose from the "sense" and "inflate" fittings on the Patient
Interface Panel. Connect an approved test device to the "sense" and "inflate" fittings on
the Patient Interface Panel.
1)
Increase the pressure testing device to 50 mmHg. The Systolic display should
indicate 56 (±3). If necessary, adjust the GAIN control, R55.
2)
Increase the pressure testing device to 100 mmHg. Verify 106 (±3) is shown on
the display. Adjust R55 as necessary.
3)
Increase the pressure testing device to 200 mmHg. The Systolic display should
indicate 206 (±4). Adjust R55 as necessary.
4)
Repeat steps 1 through 3 until no adjustments are necessary.
The overpressure switch will interrupt monitor power if excessive pressure is sensed in
the system. Do not adjust the overpressure switch unless the trip point deviates more
than -10 mmHg or +15 mmHg from the nominal specification (270 mmHg).
5)
2.
MP 1014
Number: 3.00
Continue to slowly pressurize the system and note at what pressure the monitor
cycles off to release the pressure (and go into the HOLD mode). The
overpressure trip point should be 260 mmHg or greater but not more than 285
mmHg. As the pressure reaches the expected trip point, do not increase the
pressure by more than 2 mmHg per second.
Back-up Timer
a. The monitor should be in the calibrate mode and about 50 mmHg pressure applied to the
inflate port.
b. Start a stop watch and depress the Alarm Silence button to start the Back-up Timer.

2.
Stat Mode Test, (if an NIBP probe is available)
This test verifies that the isolated pleth circuitry is performing normally.
a. Attach a finger clip probe to the finger probe connector. The monitor should be in the
"Adult" mode.
b. With a finger inserted in the probe (the 2120 should be in "Hold"), the lamp in the "SysStat" button should flash and a heart rate should appear in the "Rate" display. Dashes
may appear while the monitor locks onto the pulse signal.
c. Pressing the "Sys-Stat" button should initiate the Sys-Stat Mode (the pump will start
and the "Sys-Stat" lamp will come on continuously).
d. Press "Hold" to stop the pump.
e. With the finger probe disconnected from the finger, pressing the "Sys-Stat" button will
not light and the pump will start inflating the cuff. Press "Hold" to exit this mode.

normal polarity - neutral closed - ground open
reverse polarity - neutral closed - ground closed
reverse polarity - neutral closed - ground open
The chassis leakage current must be less than 100 microamps in all cases.
