Selecting a tolerance range that is too small can cause undesired delays.
In extreme cases, it may not be possible to continue the program. The
selected tolerance range should not be too small, especially if the control
is external. A greater tolerance has been entered for segment 5 to
guarantee adherence to the required time of 10 minutes, even with
transient responses (3).
A tolerance range should only be programmed for flat (slow) ramps,
if appropriate. Steep ramps that come close to the maximum possible
heating-up or cooling rates of the device may be severely delayed (4) if
the tolerance range is too small (in segment 2 here).

The above graph of the edited process illustrates the possible delay in the
development of the actual temperature in the bath vessel (solid line) in
relation to the set temperature of the program encoder (gray area).
