− If there is no entry in the "Time" field, the bath temperature is approached as quickly as
possible. With a time entry the final temperature is obtained exactly after the time expires
(ramp).
− The entry in the field "Tolerance" field defines how accurately the final temperature is to be
obtained before the next segment is processed.
If the tolerance range has been selected too small, it may be that the program does not
continue, because the required tolerance is never achieved.
External temperature control: Especially with ramps, a too close tolerance range can
cause undesired delays in the start phase of the ramp.
