Getting Started Teledyne API T803 CO2/O2 Analyzer Operation Manual
46
RS-485 CONNECTION
As delivered from the factory, COM2 is configured for RS-232 communications.
This port can be reconfigured for operation as a non-isolated, half-duplex RS-485
port. Using COM2 for RS-485 communication will disable the USB port. To
reconfigure this port for RS-485 communication, please contact the factory.
3.3.2. PNEUMATIC CONNECTIONS
CAUTION
GENERAL SAFETY HAZARD: CO
2
While CO
2
itself is not toxic, in sufficient concentrations it can be an irritant and
an asphyxiant.
Obtain a Material Safety Data Sheet for CO
2
and any other hazardous components
of sample and calibration gases, and follow the prescribed safety guidelines.
Do not vent sample gases into the immediate vicinity of the analyzer nor into any
enclosed areas.
CAUTION
GENERAL SAFETY HAZARD: O
2
While O
2
is itself not toxic, the sample gas measured by, and in some cases the
calibration gases used with the T803 can contain other components that are
hazardous (e.g. NO, NO
2
, SO
2
, CO, etc).
Obtain a Material Safety Data Sheet (MSDS) for each such gas. Read and
rigorously follow the safety guidelines described there.
Do not vent sample gases containing hazardous components into enclosed areas.
3.3.2.1. CALIBRATION GASES
3.3.2.2. ZERO GAS
Zero gas is similar in chemical composition to the earth’s atmosphere but
scrubbed of all components that might affect the analyzer’s readings. Teledyne
API recommends using pure N
2
when calibrating the zero point of your O
2
and
CO
2
sensors.
