Warnings and cautionary statements
This is not a contractual document. In the best interest of its customers and with the
aim of improving performance,
OLDHAM reserves the right to alter the technical
features of its equipment without prior notice.
IMPORTANT: Failure to perform certain procedures or note certain conditions may
impair the performance of this product. For maximum safety and optimal performance,
please read and follow the procedures and conditions listed below.
IMPORTANT : Read and understand this manual before operating.
WARNING : SERVICING THE UNIT OR CHANGING THE BATTERIES
MUST ONLY BE DONE IN AN AREA KNOWN TO BE NONHAZARDOUS.
Prior to each day’s use, a bump test should be performed. If the instrument
does not pass the bump test, a full calibration is recommended.
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.
Verify the calibration of the combustible gas sensor after any incident where
the combustible gas content has caused the instrument to display an over-
range condition.
Silicone compound vapors or other known contaminants 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.
When in the hazardous area, connections to the battery charging or
communications ports must be done in accordance with this technical
manual.
WARNING: Substitution of components may impair intrinsic safety and may
cause an unsafe condition.
