8.0 CALIBRATION

This section describes a method of performing a multi-point calibration of the Model 300 CO Analyzer and a method of performing a zero-span check.

8.1REQUIRED EQUIPMENT AND GAS STANDARDS

Zero air must be free of CO (less than 0.1 ppm of CO).

CAUTION

BE CAREFUL WHEN PULLING IN OUTSIDE AIR

PARTICULARLY IF OUTSIDE HUMIDITY AND

TEMPERATURE ARE HIGH. CONDENSATION

MAY RESULT WHICH CAN LEAD TO

UNSTABLE OPERATION, OR, AT WORST,

WATER CONTAMINATION IN THE CELL.

Calibration gas concentrations must be generated from an NIST-traceable cylinder of CO-in-air, such as manufactured by Scott-Marrin. Carrier air for transporting the CO must be the same as the zero air. A suggested calibration gas generating system is shown in Figure 8.1.

The materials in the calibration gas delivery system should be stainless steel, TFE and FEP (Teflon). The system must be clean.

The calibration gas delivery system (or manifold) must be properly vented near the Analyzer inlet to avoid imposing a pressure or vacuum at the inlet. The recommended venting method is shown in Figure 8.2.

Teledyne 300 Calibration, 8.1REQUIRED EQUIPMENT AND GAS STANDARDS, Be Careful When Pulling In Outside Air

FAQ

What equipment and gas standards are required for calibration?

Zero air must be free of CO less than 0.1 ppm, and calibration gas concentrations must be generated from an NIST-traceable cylinder of CO-in-air.

What precautions should be taken when pulling in outside air?

Be careful, particularly if outside humidity and temperature are high, as condensation may result which can lead to unstable operation or water contamination in the cell.

What materials should the calibration gas delivery system be made of?

Stainless steel, TFE, and FEP Teflon are recommended for the materials in the calibration gas delivery system.
