1. WARNINGS AND CAUTIONARY STATEMENTS

Failure to perform certain procedures or note certain conditions may impair the performance of the instrument. For maximum safety and performance, please read and follow the procedures and conditions outlined below.

!Oxygen deficient atmospheres may cause combustible gas readings to be lower than actual concentrations.

!Oxygen enriched atmospheres may cause combustible gas readings to be higher than actual concentrations.

!Calibrate the combustible gas sensor after each

incident where the combustible gas content causes the instrument to latch in the OVER-RANGE alarm condition.

!Silicone compound vapors may affect the combustible gas sensor and cause readings of combustible gas to be lower than actual gas concentrations. If the instrument has been used in an area where silicone vapors were present, always calibrate the instrument before next use to ensure accurate measurements.

!Sensor openings and water barriers must be kept clean. Obstruction of the sensor openings and/or contamination of the water barriers may cause readings to be lower than actual gas concentrations.

!Sudden changes in atmospheric pressure may cause temporary fluctuations in the oxygen reading.

!Recharge battery only in a non-hazardous location.

!Use the RS-232 port only in a non-hazardous location.

!Instrument is tested for intrinsic safety in explosive gas/air (21% oxygen) mixtures only.

CAUTION: High Over-Range (+OR) combustible

! gas readings may indicate an explosive concentration of combustible gas.
