The two scales are subordinated to the working range
selected in the sensors.
range selected on 20% sensors = 10-20% scale
range selected on ensors at 100% = scale 10-50%
The first 10-20% scale can be set as desired keeping in
mind that the intervention threshold cannot be lower than
the pre-alarm.
To be set, the second scale needs:
a) set the probe concerned to detect 100%.
b) a password is required to proceed
