Each program begins with the segment "Start". It defines at which temperature Seg-
ment 1 is to continue the program. It is not possible to specify a time for the Start
segment.

It facilitates exact conformance to the dwell time at a specified temperature. Segment
1 is not processed until the bath temperature is within the tolerance range Œ, so that
the ramp (Segment 2) starts delayed at •.
A tolerance range which is too tight can however also cause undesired delays. In
particular with external control the range should not be chosen too tightly. In
Segment 5 a larger tolerance has been entered, so that the desired time of ten
minutes is maintained even with settling action Ž.
Only flat (slow) ramps should be programmed where necessary with a tolerance
range. Steep ramps, which lie close to the maximum possible heating or cooling
rates of the thermostat, may be severely delayed by a tolerance range that is too
tight (here in Segment 2) •.

Example for the influence of the tolerance field in-
put in case of external control:
The setpoint temperature of the programmer is
shown in grey.
The actual temperature in the external bath con-
tainer is represented as a continuous line.
