Segment 1 isnot processed until the actual temperature is within the tolerance band n, so that the ramp(Segment 2) starts delayed at o.− A tolerance range which is too tight can however also cause undesired delays. In particularwith 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 withsettling action p.− 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)q.Example of the effect of the tolerance input withexternal bath control:The setpoint temperature of the programmer isshown in grey.The actual temperature in the external bath container isrepresented as a continuous line.7.8.2 Creating or changing a program (editing)Here, there are the following functions:• Create a program.• Display the program data of a saved program and change the segment data.• Insert or append a new segment.• Delete a segment.°C80706050403020100 20 40 60 80 100 120 t/minn o q n pGraph 2
