The field "Tolerance" (Refer to programming table above and graph below):
− It facilitates exact conformance to the dwell time at a specified temperature. Segment 1 is
not processed until the actual temperature is within the tolerance band
(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 tol-
erance has been entered, so that the desired time of ten minutes is maintained even with
settling action
− 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 ther-
mostat may be severely delayed by a tolerance range that is too tight (here in Segment 2)
