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.
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.

Oxygen
MOnitOr
CAUTION
1. Calibrate the Oxygen Monitor before each use, and when replacing the
Oxygen Sensor or the batteries.
2. 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 inaccurate readings.
3. 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.
4. Calibrate the Oxygen Monitor at a pressure and flow similar to your clinical
application.
5. Before calibrating the Oxygen Monitor, the oxygen concentration readout
should be stable and not drifting more than 0.2%.
6. DO NOT calibrate the Oxygen Monitor in humidified gas, as water vapor
makes the oxygen concentration appear lower than the actual value.
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.
6. Press the CAL key. The display will show “@ 21%” or “@ 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.
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

13
Oxygen
MOnitOr
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.
EFFECT OF PRESSURE:
CAUTION
The Oxygen Monitor is no equipped with automatic barometric
pressure compensation.
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.

CAUTION
The Oxygen Sensor should not be used in the presence of ammable
anesthetics such as Diethyl Ether or Cyclopropane.
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.
Operator’s Position - Visual alarms are best viewed at a distance of 3 feet
(1m) or less from the Oxygen Monitor along with the following conditions;
– the Operator has a visual acuity of 0 on the logMAR scale or 6-6
(20/20) vision(corrected if necessary),
– the viewpoint is at the Operator’s Position or at any point within an
angle of 30° to the axis horizontal to the centre of the plane of the
monitoring display, and
– the ambient luminance in the range of 100 lx to 1 500 lx.
TO SET ALARMS
WARNING
Do Not set alarm limits to extreme values that can render the alarm
system useless.
