Protégé Portable Gas Monitor
Instruction Manual
30 of 61
P/N 087-0038 Rev. J 02/10
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.
