9.1. BEFORE CALIBRATION
The calibration procedures in this section assume that the range mode, analog
range and units of measure have already been selected for the analyzer. If this
has not been done, please do so before continuing (see Section 5.2 for
instructions).

9.1.1. REQUIRED EQUIPMENT, SUPPLIES, AND EXPENDABLES
Calibration of the T803 analyzer requires a certain amount of equipment and
supplies. These include, but are not limited to, the following:
supplies. These include, but are not limited to, the following:
Zero-air source.
Span gas source.
Gas lines - All Gas lines should be Stainless Steel, PTFE (Teflon), glass or
Span gas source.
Gas lines - All Gas lines should be Stainless Steel, PTFE (Teflon), glass or
electroless nickel.
A recording device such as a strip-chart recorder and/or data logger (optional).
For electronic documentation, the internal data acquisition system can be
used.

9.1.2. CALIBRATION GASES
9.1.2.1. ZERO AIR
A gas that 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
