AQT (1) AQT (2)
In the above application there is no billet snap shot function instead there are
two quenching zones.
The basic LMG AE configuration for the above would be as follows:
Set CHA to have an AET thermometer selected.
Set CHB to have an AQT thermometer selected.
Set CHC to have an AQT thermometer selected.
Set CHD to have a speed sensor selected.
There are three possible quench rate calculations i.e.
1 AET => AQT (1)
2 AET => AQT (2)
3 AQT (1) => AQT (2)
The user must choose the two of interest which can then be
calculated independently.
