CAUTION
• Activate the detector before the activation date on the package.
• This product is a gas detector, not a measurement device.
• Ensure that the sensor grill is free of dirt, debris, and is not obstructed.
• Clean the exterior with a soft, damp cloth.
• For optimal performance, periodically zero the sensor in a normal atmo-
sphere (20.9% v/v O
• Portable safety gas detectors are life safety devices. Accuracy of ambient
gas reading(s) is dependent upon factors such as accuracy of the cali-
bration gas standard used for calibration and frequency of calibration.
Honeywell Analytics recommends performing a calibration at least once
every 180 days (6 months).
• The combustible gas sensor is initially calibrated to 50% LEL methane.
Only methane gas should be used to calibrate or bump test the com-
bustible gas sensor.
• Only the combustible gas detection portion of this instrument has been
assessed for performance.
• High off-scale readings may indicate an explosive concentration.
• Any rapid up scaling reading followed by a declining or erratic reading
may indicate a gas concentration beyond the upper scale limit, which can
be hazardous.
• Products may contain materials that are regulated for transportation un-
der domestic and international dangerous goods regulations. Return
product in compliance with appropriate dangerous goods regulations.
Contact freight carrier for further instructions.
• Recycling: this instrument contains a lithium battery. Do not mix with the
solid waste stream. Spent batteries should be disposed of by a qualified
recycler or hazardous materials handler.
