As stated in “Reading patterns” the device can work in two different readings modes (Chess pattern – the default one
and IL (Interleave mode)).
Depending on the device measurement mode and GOYF
jhi•SR
Í N we can define a pattern which will help us
to automatically switch between both subpages.
- In case of Chess pattern is selected please use following expression:
