This parameter affects the temperature pattern only in
case of internal control.
Possible parameters:
NORM Allows for reaching the setpoint faster, but
overshooting of up to 5 % is possible.
APER
Target temperature is attained without
overshooting.

With both adjustments an adequate temperature
stability is reached after approximately the same time.
1. Press the button until the submenu > DYN INT < is displayed.

9.2.4. Control parameters – XP, TN, TV internal
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.
