9.5. Control parameters – Xp, Tv, Tn
The control parameters preset in factory are in most cases adequate for
achieving an optimum temperature pattern for the samples requiring
temperature application.
Each parameter may be manually set via the keypad if necessary, to
allow optimum control performance.
Setting range:
0.1 ... 99.9
Proportional range >Xp<
The proportional range is the range below the selected temperature value
in which the control circuit reduces the heating power from 100 % to 0 %.
Setting range::
1 ... 9999
Resetting time >Tn< (Integral component)
Compensation of the remaining control deviation due to proportional
regulation. An insufficient resetting time may cause instabilities to occur.
Excessive resetting time will unnecessarily prolong compensation of the
control difference.
Setting range:
0 ... 99
Lead time >Tv< (Differential component)
The differential component reduces the control settling time. An
insufficient lead time will prolong the time required to compensate for
disturbance effects and cause high overshooting during run-up. An
excessive lead time could cause instabilities (oscillations) to occur.
