Warnings and Cautionary Statements
CAUTION: Failure to perform certain procedures or note certain conditions may
impair the performance of the monitor. For maximum safety and performance,
please read and follow the procedures and conditions outlined below.

Oxygen deficient atmospheres may cause combustible gas readings that use
catalytic LEL sensors to be lower than actual concentrations.

Oxygen enriched atmospheres may cause combustible gas readings that use
catalytic LEL sensors to be higher than actual concentrations.

Calibrate the catalytic combustible gas sensor after each incident where the
combustible gas content causes the instrument to enter in the OVER-RANGE
alarm condition.

Silicone compound vapors may affect the catalytic combustible gas sensor and
cause readings of combustible gas to be lower than actual gas concentrations. If
the sensor has been used in an area where silicone vapors were present, always
calibrate the instrument before continued use to ensure accurate measurements.

Sensor openings must be kept clean. Obstruction of the sensor openings may
cause readings to be lower than actual gas concentrations.

Sudden changes in atmospheric pressure may cause temporary fluctuations in
the oxygen readings.

Alarms relays are non-latching.

When connecting 4-20 mA outputs to inductive loads, Oldham recommends
using an isolation barrier in line with the 4-20 mA signal.

Interior grounding terminal is to be used for grounding, the exterior terminal is
only to be used for bonding

iTrans Stand-Alone versions with on-board visible alarm are to be
installed in ordinary locations only; however, remote sensors can be
installed in hazardous locations (Gas dependent. Read Agency
Approvals paragraph).
