ramp down, a soak or a ramp up respectively.
When a program starts, the middle display shows:
- the operative set point value, if the segment is a ramp
- the remaining time to end the segment, if the segment is a
soak.
NOTE: if the remaining time is more than 1 hour, it will be
shown in hours and minutes, if, the remaining time is less than
1 hour, it will be shown in minutes and seconds.
The lower display shows the running program number on the

segment in progress on the two LSD; the decimal point at the
left of the 2 LSD lit.

information on the middle and lower displays.
