QUICK SETUP GUIDE
1. Install 4 AA Alkaline Batteries.
2. Connect the Oxygen Sensor and Diverter Fitting.
3. Connect the Coiled Cable.
4. Calibrate the Oxygen Monitor.
5. Set the High/Low Alarms.
SENSOR INSTALLATION
CAUTION
• Inspect the Oxygen Sensor and Diverter Fitting for visual
damage or electrolyte leakage before use. DO NOT USE
if damaged.
• Use ONLY an Oxygen Sensor specied by Precision
Medical, Inc.
• The Oxygen Sensor should not be used in the presence
of ammable anesthetics such as Diethyl Ether or
Cyclopropane.
WARNING
• DO NOT attempt to open or repair the Oxygen Sensor.
• The Sensor electrolyte is corrosive, and contains lead.
DO NOT let it come in contact with the skin. If it does,
ush affected area with water.
• Check the Sensor regularly for leaks. If the Sensor is leaking,
replace with NEW Sensor. Leaking or used Sensors should be
handled and disposed of in accordance with local regulations.
An MSDS is available from Precision Medical, Inc.
• If the Oxygen Sensor is used in breathing circuits, the
Diverter must be attached to the Sensor and must be used
with the Tee Adapter.
• The Oxygen Sensor must be installed before the Oxygen
Monitor can be operated.
1. Screw the Diverter to the bottom of the Oxygen Sensor,
tighten until snug.
2. If using the Tee Adapter, attach to the Diverter.
3. Insert the one end of the Coiled Cable into the top of the
Sensor, and secure by tightening the Locking Ring, until
snug.

12
Oxygen
MOnitOr
4. Insert the other end of the Coiled Cable into the Sensor
Cable Connection located on the right side of the Oxygen
Monitor. Secure it in place by tightening the Locking Ring,
until snug.
5. Wait approximately 20 minutes for the NEW Sensor to
stabilize to the environment.
6. Calibrate the Oxygen Monitor with the NEW Sensor.
CALIBRATION
1. Place the Sensor with Diverter and Plastic Tee attached
into the gas stream of 100% USP Oxygen or room air. The
highest accuracy is achieved when using 100% USP Oxygen
at a constant pressure and ow.
2. Wait at least 20 seconds or more for the oxygen to purge the
line.
3. Turn the Oxygen Monitor “ON” by pressing the POWER
key.
4. Let the oxygen concentration display stabilize, the readout
should not drift more than 0.2%.
5. Press the key to UNLOCK the keys.
CAUTION
• Calibrate the Oxygen Monitor before each use, and when
replacing the Oxygen Sensor or the batteries.
• The Precision Medical Oxygen Monitor can only be
calibrated accurately using 100% Oxygen or 20.9%
Oxygen (Room Air). Using any other concentration will
result in a inaccurate readings.
• Air calibration is not recommended unless the Sensor can
be exposed to a known source of clean air. Hospital room
air is often enriched with excess oxygen.
• Calibrate the Oxygen Monitor at a pressure and ow
similar to your clinical application.
• Before calibrating the Oxygen Monitor, the oxygen
concentration readout should be stable and not drifting
more than 0.2%.
• DO NOT calibrate the Oxygen Monitor in humidied gas,
as water vapor makes the oxygen concentration appear
lower than the actual value.

EFFECTS OF TEMPERATURE:
To minimize temperature effects:
1. In a breathing circuit, place the Oxygen Sensor upstream of
the heater.
2. Allow time for the Oxygen Sensor to stabilize to its new
room temperature.
3. Perform the calibration procedure at a temperature close to
or similar to your clinical application.
EFFECTS OF HUMIDITY:
High Moisture levels will dilute the oxygen concentration,
decreasing the concentration of oxygen being monitored by
the Oxygen Sensor.
High humidity can cause condensation to collect on the
Oxygen Sensor, obstructing the passages and reducing the
effectiveness of the Oxygen Sensor.
CAUTION
To reduce the effects of humidity on the Sensor:
• DO NOT USE the Oxygen Sensor in environments with
greater than 95% humidity.
• Place the Oxygen Sensor upstream from the humidier
in a breathing circuit.
6. Press the CAL key. The display will show “CAL @ Air” or
“CAL @ 100” oxygen. When “DONE” appears, the calibration
is complete. The Oxygen Concentration will be displayed in
a gas percent value. Press LOCK/UNLOCK to save the
calibration data. If no keys are pressed within 3 seconds, the
setting will be saved, and the keypad will be locked.
7. Remove the Oxygen Sensor from the oxygen supply and
conrm that the display reads between 19-22% Oxygen in
room air.

14
Oxygen
MOnitOr
EFFECT OF PRESSURE:
When the Oxygen Sensor is placed in a breathing circuit, the
alternating “breathing” pressure cycles will be sensed as an
increase in oxygen concentration. The concentration is not
actually changing, but it appears to be due to the change in
pressure.
The following recommendation is provided to reduce the
chances of pressure causing false readings.
Calibrate the Precision Medical Oxygen Monitor using 100%
Oxygen or room air at the same pressure and ow as the gas
to be monitored.

ALARMS
The Precision Medical Oxygen Monitor will store the HIGH/LOW
alarm settings in memory after the Oxygen Monitor is turned
“OFF”.
The Oxygen Monitor is designed to prevent crossing of the HIGH/
LOW alarm settings. The LOW alarm cannot be set above the HIGH
alarm and the High alarm cannot be set below than the LOW alarm.
TO SET ALARM:
1. With the Power key ON.
2. Press the LOCK/UNLOCK key.
3. To set the HIGH Alarm: Press the HIGH ALARM SET key
once. Press the UP and DOWN arrow keys until the
desired value is displayed next to the Up arrow in the upper
right corner of the display. Continuously pressing the arrow
keys will move the value in increments of 5. Press the
HIGH ALARM SET key to save the setting. Flashing Number
indicates the Number can be changed. If no keys are pressed
for 10 seconds, the setting will be saved and the Oxygen
Monitor will revert to locked mode.
4. To set the LOW Alarm: Press the LOW ALARM SET key
once. Press the UP and DOWN arrow keys until the
desired value is displayed next to the Down arrow in the
lower right corner of the display. Continuously pressing the
arrow keys will move the value in increments of 5. Press
the LOW ALARM SET key to save the setting. Flashing
Number indicates the Number can be changed. If no keys are
pressed for 10 seconds, the setting will be saved and the
Oxygen Monitor will revert to locked mode.
5. Lock the display by pressing the LOCK/UNLOCK key.
6. To disable the HIGH Alarm, raise the HIGH Alarm setting
above 100%. “---” will be displayed next to the Up arrow on
the display. The LOW alarm will still function while the HIGH
alarm is disabled.
