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
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 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
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 with
external bath control:
The setpoint temperature of the programmer is
shown in grey.
The actual temperature in the external bath container is
represented as a continuous line.
