5. Calibration
The following sections describe how to calibrate the span and zero points of the instrument as well as
giving a brief overview of the calibration system.

5.1 Overview
Figure 111 – Example of a Calibration System
CAUTION
All calibration gases must be supplied at ambient pressure to avoid damaging the
instrument. If direct gas cylinder connection is required, high pressure Zero/Span
options can be installed at time of ordering.
The calibration chapter consists of a:
General discussion of calibration.
Description of the pressure calibration procedure.
Description of the Zero/Span precision check and calibration procedures.
Description of the multipoint precision check procedure.
The Serinus 30 analyser is a precision measuring device which must be calibrated against a known
source of CO (e.g. a certified gas cylinder).
