1.3.2. Combustible Sensor Warnings and Cautions
The following list of warnings and cautions pertain to the general use and care of the sensors within
the Protégé.
Failure to follow these warnings and cautions may result in death, injury, or poor equipment
performance.
WARNINGS
EXTENDED EXPOSURE OF THE DETECTOR TO HIGH CONCENTRATIONS OF TOXIC OR COMBUSTIBLE GASES MAY
RESULT IN DEGRADED SENSOR PERFORMANCE.IF AN ALARM OCCURS DUE TO HIGH CONCENTRATION OF
COMBUSTIBLE GASES,RECALIBRATE THE MONITOR OR,IF NEEDED,REPLACE THE SENSOR.
THE COMBUSTIBLE SENSOR REQUIRES 10% OXYGEN IN THE ATMOSPHERE TO OPERATE.IF YOU ARE UNAWARE
OF THE OXYGEN CONCENTRATION OR IF THE OXYGEN CONCENTRATION IS BELOW 10% DO NOT USE THE
PROTÉGÉ TO MONITOR FOR COMBUSTIBLE GAS CONCENTRATIONS.
CAUTIONS
DO NOT USE ANY SOLVENTS,CHEMICALS,OR POLISHES CONTAINING SILICON COMPOUNDS TO CLEAN THE
DETECTOR AS THESE CAN CAUSE DAMAGE TO THE SENSOR.
SENSITIVITY OF THE COMBUSTIBLE GAS SENSOR CAN BE ADVERSELY AFFECTED BY EXPOSURE TO SULFUR
COMPOUNDS,HALOGENS,SILICONE OR LEAD CONTAINING COMPOUNDS,OR PHOSPHORUS CONTAINING
COMPOUNDS.AVOID EXPOSURE TO THESE SUBSTANCES.SHOULD THE DETECTOR BE SUSPECTED OF BEING
EXPOSED TO SUCH SUBSTANCES,PERFORM A GAS TEST TO VERIFY ITS ACCURACY AND THAT IT IS CALIBRATED
ACCORDINGLY.

1.4.General Rules for Use of the Protégé
It is critical that this gas detector be used and maintained properly. Failure to do so could jeopardize
the people whose lives depend on its operation and cause injury or death.
•USE THE MONITOR CORRECTLY! Only use the Protégé to monitor the atmosphere for the
gases and concentrations for which it is set-up to detect.
•POWER MUST BE ON TO WORK. The Protégé will only detect gases while powered on and
not while connected to the PC or in Calibration mode. Immediately charge battery when a low
battery alarm occurs.
•PERFORM A DAILY FUNCTIONAL BUMP TEST Before each day’s use, test the sensors
using a known concentration of calibration gas. The monitor should indicate a gas
concentration within 10% of the actual gas listed on the calibration cylinder label. When the
gas indication is outside the 10% limit span calibration should be performed.
WARNING
PERFORM A BUMP TEST EVERY DAY.FAILURE TO PERFORM A DAILY FUNCTIONAL TEST COULD LEAD TO SERIOUS
INJURY OR DEATH.
•BE AWARE OF Poisoned Combustible Sensors! Operation of catalytic type combustible
gas sensors may be seriously affected by silicones, free halogens, halogenated
hydrocarbons and metallic oxides present in the ambient air being monitored. If the presence
of any of these substances is suspected, increased frequency of calibration verification is
recommended.
•WHEN IN DOUBT – LEAVE THE AREA IMMEDIATELY! Users should leave the area
immediately should the Protégé indicate a warning or alarm condition. Users should know
and understand their company’s safety protocols.
•CALIBRATION IS CRITICAL! Calibration should be performed periodically that takes into
account monitor use and environment conditions.
oAdditionally, the Protégé should always be re-calibrated:
After exposure to high concentrations of toxic or combustible gases or vapors.
If the monitor is dropped, or the monitor is drenched in water or submerged.
After a change in monitor custody.
•ALARMS AND OUT-OF-RANGE CONDITIONS! Operators should be aware of conditions
where the concentration of the gas is outside the detectable range of the monitor. If the
monitor indicates an over-range condition, leave the area immediately. If an over-range
condition is encountered, perform a Bump Test to ensure monitor functionality. If the monitor
fails the Bump Test, perform a full calibration procedure.

2. Introduction
The Protégé unit comes installed with a re-chargeable lithium ion battery and sensors already
installed and ready for use. A CD-ROM containing the Protégé Gas Monitor software comes with the
unit and must be installed to modify Protégé settings or capture data from the unit.
Depending on the sensors it is equipped with, the Scott Protégé personal multi-gas monitor is
designed for monitoring the atmosphere for potentially hazardous levels of combustible gases,
oxygen enrichment or depletion, carbon monoxide, and hydrogen sulfide.
Gas indication is displayed to users by a direct reading backlit LCD, multiple bright LEDs, a loud
audible alarm, and a vibratory alarm. The Protégé includes a downloadable data log for up to 4000
events and records STEL / TWA / PEAK exposures, calibrations, and gas values. A built-in USB
port on the charging module allows the monitor’s data log to be downloaded and, when used with
the Protégé’s interface software (included), allows users to quickly configure its operating and alarm
parameters.
The Protégé is powered by a long life rechargeable lithium-ion battery. An optional sample draw
pump is available for remote sampling. Additionally, an optional multi-charger is available that will
charge up to six Protégé units simultaneously.
Refer to Figure 2-1 and Figure 2-2.
