System Calibration
1 Introduction
In opposite to the possibility to zero and span each analyzer module (channel) individually and independently from the others,
This is been achieved with a new assignment of the valves. The idea is not longer to require for each gas of each analyzer an own valve.
Instead of we have a pool of valves. The valves of this pool can be assigned to the different gases of the analyzers. That also means different analyzers can share the same valve for their gases. So we have the possibility to reduce the number of valves and also the consumption of calibration gases.
The program, which will allow this, runs on the Control Module (CM) and needs the programmable I/O (DIO and SIO).
The displayed menus are also inscripted with the appropriate network variables.
