•
Perform a Self-Test prior to each day's use (See Section -1 Performing a
Self-Test).
•
Periodically test the sensors' response to gas by exposing the monitor to a target gas
concentration that exceeds the alarm set points. Verify proper operation of audible,
visual and vibrating alarms during this test.
•
Use only factory supplied calibration gas for calibration. Accurate calibration
can be achieved only if specific concentrations of the correct gases are
used.
•
Calibration should be carried out in a well-ventilated area to avoid
contaminants.
•
Calibration cannot be carried out when the detector emits a low battery
alarm.
•
Do not use the detector in oxygen-enriched atmospheres.
•
The flammable sensor's sensitivity can be adversely affected by exposure
to certain substances called "poisons". Sulfur compounds, phosphorus
containing compounds, halogens, silicone or lead containing compounds
are examples of such poisons. Every effort should be made to avoid
exposure to these substances. When the detector is exposed to such
substances, a gas test should be performed on the flammable sensor
to verify its accuracy and a calibration performed if necessary.
•
Extended exposure of the detector to certain high concentrations of flammable
gases and air may stress the flammable detector element, which can
seriously affect its performance. If an alarm occurs due to high concentration
of flammable gases, recalibration should be performed, or if needed, the
sensor replaced.
•
Do not use solvents, soap, polishes or any product containing silicon
compounds to clean the detector as these can cause damage to the
sensors.
•
Do not expose the detector to electrical shock and/or severe mechanical
shock. When the detector is exposed to such shocks, a check should be
performed on the sensors to verify its accuracy and a calibration performed
if necessary.
•
Disabling one or more installed sensors configures the detector to a 1, ,
or -gas unit. No protection is provided for the gas targeted by the disabled
sensor(s).
•
Do not install or remove the memory card in the detector or attempt to read,
download or write to the memory card using a memory card reader and/or
computer in potentially hazardous atmospheres.
•
Do not remove the batteries from the detector while the power is on. This can
cause fatal damage to the optional memory card if installed.
•
No gas will be detected while in the set-up mode or the gas exposure status
review mode.
•
The desktop USB memory card reader and data logging kit are not
certified intrinsically safe and must not be used in potentially hazardous
atmospheres.
