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.
o Additionally, the Protégé should always be re-calibrated:
ƒ After exposure to high concentrations of toxic or combustible gases or vapors.
ƒ If the monitor is dropped, or the monitor is drenched in water or submerged.
ƒ 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.

4.2. LCD Alerts and Displays
4.2.1. Gas Warning and Alarm Alerts
Both gas warnings and alarms will blink the specific gas type that is in alert. Audible, visual, and
vibrating alarms will activate and the concentration / value of the sensor in alarm will be indicated.
If a Gas Type Label blinks with no alarm present, the sensor is detecting a negative drift. Perform a
Zero Calibration to clear the drift.
If the option to Operate with Failed Sensors has been enabled using the Gas Monitor Software, the
Protégé will display FAL in place of the reading for that particular sensor. This option is not
recommended for use unless careful consideration is given to the reduced monitoring capabilities of
the Protégé and follows locally established practices.
4.2.2. Low Battery
The battery charge icon will blink and monitor will activate the visual, audible, and vibratory alarms
when a battery becomes low. Low battery conditions can be silenced by pressing the left button.
Users should immediately exit the environment and charge the Protégé as soon as a low battery
alarm is indicated.
4.2.3. Over-Range Conditions
If a sensor within the monitor is exposed to a target gas concentration that exceeds the sensor’s
range, the Protégé will activate its visual, audible, and vibratory alarms and display +++ at the
sensor’s location on the LCD. Alarms conditions will clear when the gas concentration has subsided.
WARNING
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.
FAILURE TO DO SO COULD RESULT IN INACCURATE MONITORING BY THE UNIT AND CAUSE DEATH OR INJURY.
4.2.4. Low Flow Pump Warning
Low Flow Pump Warning is displayed when airflow through the pump is diminished or restricted and
could compromise accurate readings. Protégé shuts down the pump and the monitor goes into
audible, visual, and vibratory alarm while the PUMP icon flashes. After the cause of the low pump
flow is cleared, reset the pump by pressing and releasing the Left or Right button.
4.2.5. Sensor Failures
FAL will be indicated for each sensor that fails to zero or span calibrate. Should this occur,
recalibrate the monitor. If a sensor continues to fail, replace the sensor and recalibrate or contact an
authorized service center.

4.3. Protégé Calibration and Bump Test
WARNING
OPERATING A PROTÉGÉ MONITOR THAT HAS EXCEEDED ITS CALIBRATION DATE CAN CAUSE FALSE READINGS OF
DETECTED GASES. READINGS OBTAINED WHILE UNIT IS OUT OF CALIBRATION ARE INVALID AND COULD LEAD TO
DEATH OR INJURY.
CAUTION
IF CAL EXPIRED IS DISPLAYED UPON POWER ON START UP SEQUENCE INDICATING THE UNIT DOES NOT HAVE
VALID CURRENT CALIBRATION, PRESS THE RIGHT OPERATIONAL BUTTON TO OVERRIDE AND IMMEDIATELY
CALIBRATE THE MONITOR. FAILURE TO DO COULD RESULT IN INACCURATE MONITORING BY THE UNIT SENOSRS.
Scott Health & Safety recognizes the potential of the Protégé as a life saving device when operated
and maintained correctly. As such, verifying proper operation of the Protégé in the form of Span
calibration and daily Bump Testing is essential to ensure the Protégé performs as intended in a
potentially hazardous environment.
The frequency at which Span calibration and Bump Testing occur is best determined based on local
regulatory standards, company policies, and industry best practices. Scott Health & Safety is not
responsible for setting policies or practices.
Calibration of the Protégé occurs in two stages. Zero calibration is performed to establish baseline
readings of atmospheres that are known to be free of toxic or combustible gases. Span calibration is
performed to ensure the monitor detects target gases within specified operating parameters.
Span calibration is the adjustment of the Protégé’s response to match a known concentration of gas.
Sensors can lose sensitivity through normal degradation, exposure to high gas concentrations, or
sensor poisoning. Accurate calibration can be achieved only if specific concentrations of the correct
gases are used. Span calibration should be performed when a new sensor is installed or when the
Protégé displays CAL EXPIRED. Span calibration must be performed anytime a daily Bump Test
fails.
Bump Testing verifies the Span calibration by subjecting the Protégé to a known exposure of gas,
verifying the response is within 10% of actual concentration and verifies that all alarms work
properly. Scott Health & Safety recommends a daily Bump Test be performed prior to each day’s
use and whenever the sensor has been exposed to a high gas concentration, submerged in water,
or exposed to mechanical shock such as being dropped.
Scott Health & Safety recommends a daily Zero calibration be performed prior to each day’s use
and when the monitor displays a reading other than its baseline reading in an atmosphere known to
be free of any toxic or combustible gases. When an atmosphere is not known to be free of toxic or
combustible gases, a Zero Air calibration cylinder may be used.

5.4. Pump Cleaning Procedure
The Protégé’s pump requires periodic cleaning to ensure optimum performance. The pump may be
cleaned as part of a preventative maintenance schedule, which will depend on the frequency of
usage and the environmental conditions under which the pump is used.
Perform the pump-cleaning procedure if:
•
•
•
•
The pump fails the start-up flow test.
The instrument periodically goes into Low Flow Alarm without apparent reason.
The pump makes a chattering noise during operation.
The sample draw reading indicates less than 300 cc/min (0.3 Lpm).
To clean the optional pump assembly, perform the following.
Equipment Required:
•
•
•
•
•
10ML Syringe (077-0422)
Tygon Tubing (40011392)
T8 Torx head screw driver (073-0324)
Isopropyl Alcohol (IPA)
Canned compressed air (Electronic Grade)
1) Using the T8 Torx head driver, remove the four Torx head screws located on the back of the
pump assembly.
Figure 5-4.

Syringe Set-up
7) Slowly inject the alcohol through the pump by pressing the plunger on the syringe.
8) Once the alcohol is inside the pump and tubing, pump the syringe plunger in and out 5-7
times. Then depress the syringe plunger completely to eject the alcohol from the pump.
9) Carefully disconnect the Tygon tubing from the pump ports.
10) Use the can of compressed air to blow the excess alcohol from the pump. The thin tube that
comes with the can of air may be helpful in directing the air stream into the pump ports. The
pump should make an audible whir as it spins.
11) Re-attach the pump tubing to the INLET (long) and OUTLET (short) ports.
12) Place the pump assembly into the enclosure with the ports positioned over top of one
another. The INLET port should be higher than the OUTLET port. Verify the wires are routed
on top of the assembly as shown in Figure 5-8.

Appendix
Combustible Sensor K-Factors
The table lists K-factors referenced to methane calibration. The factors are the typical ratios of the
response to the listed gases relative to the response to methane. The values are typical, but will
vary from sensor to sensor and over the lifetime of a given sensor. When a gas other than the
calibration gas is detected, divide the reading by the corresponding factor to estimate the actual gas
concentration. For example, propane may be detected by a Protégé calibrated with methane. If the
reading is 32% LEL: 32% LEL Methane indicated/0.65 = 49% LEL of propane, estimated. Generally,
if there is a potential for methane in the operating environment, the instrument should be calibrated
with methane. If there also is a potential for other gases in the operating environment, the LEL alarm
level should be adjusted according to the lowest K-factor of the expected gases. For example, if
either methane or propane may be present, and the desired alarm is 25% LEL, calibrate the
instrument with methane and set the alarm level at (25% x 0.65 = 16% LEL). For best accuracy,
calibrate the Protégé with a gas similar to the monitored target gas.
