2.3 - Manual Operating Mode
The display shows the selected temperature value of the block and also the
current block temperature or thermo-element temperature value.
There are 4 ways in which the information are shown, covering the calibrator
input value (IN), the block temperature (PROB) and the temperature setpoint (SET). The
key
interchanges the display presentation way:
The block temperature setpoint is selected directly by the keypad, even if the
message SET is not being displayed. The numeric keypad enables the SET selection in
any of the display presentation ways, to change the setpoint.
The setpoint value is increased by key
keys are kept pressed, the setpoint continues to be increased or decreased.

1200PH calibrators.
Intermally, the setpoint changes at a limited rate to make possible a safer and
more homogeneous heating of the internal ceramic tube. Besides, the PID parameters
and algorithm were adjusted to assure a minimal stabilization time and overshoot.
2.4 - Programmable Operating Mode
Pre-configured programs can be loaded from the calibrators memory, enabling
the programmable operating mode. The temperature programmed values of the block
are used directly, with no need to enter the setpoint.
The display shows STEPn beside the block temperature setpoint value in the
programmable mode. The number of the program is indicated by n. Using the keys
and
, the programmed values of temperature setpoint are changed. The numeric
keypad continues available for manual selection of the block temperature in the same
way of the manual operating mode.
The automatic scan over the programmed temperatures is implemented by
defining the stabilization time of the thermo-element in the block.
