Start/stop/end via conditions
Start, stop and end the process by means of various conditions, e.g. start
when a value exceeds the reference value, stop and end when certain values
fall below the reference value.

Notes
S The process is halted immediately without waiting for your stop or end con
ditions if you click on or the relevant interface command arrives.
S The conditions are only analyzed when a value has already dropped below
the reference value plus hysteresis or risen above the reference value
minus hysteresis once. The hysteresis is 1% of the range window for the
start condition, and 5% of the range window for the stop and end conditions.
The percentage refers to the relevant axis of the range window. The hys
teresis is necessary to ensure that noise or minor signal interference does
not already interrupt the measurement at time tx.
