Figure 3-10. Average ISO Parameters
To select further information in the form of charts and graphs for each of the parameters, select
the buttons below the bar charts for each track. These parameters are described below and
illustrated in Section 4, Graphic Presentations. The parameters are also discussed in Appendices
A and C of this manual.
ISO Limits and Measurement Uncertainty
The ISO Limits specified under the View menu are a composite of two ISO specifications: 7811-
2 and 7811-6. These values are the widest ISO limits of both specifications. They were selected
because LoCo and HiCo values are different, and Readers in the field read reliably with cards
encoded within these combined limits.
