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.
