3.5. CONFIGURING THE INTERNAL ZERO/SPAN OPTION (IZS)
In order to use the IZS option to perform calibration checks, it is necessary to configure
certain performance parameters of the O
3
Generator.
3.5.1. VERIFY THE O
3
GENERATOR AND EXPECTED O
3
SPAN

As is true for T400 analyzers without options, when the IZS option is present the O
3
span concentration value also automatically defaults to 400.0 PPB. In this case, no
external source of calibration gas is required; however, it is necessary to verify that the
internal O

generator is set to produce an O
3
concentration of 400.0 PPB.
