5.2
Calibration (calibration mode)
As soon as the calibrator has been switched on, it switches to the
calibration mode
after
initialization
5.2.1
Display of reference and set temperature
The current reference temperature is displayed in the upper and the set temperature in the
lower of the display.
Upper display (red):
The red display shows the current temperature of the
metal block or of the calibration liquid.
The red display also shows the selected function
alternately to the temperature if the calibrator has
several functions.
Lower display (green):
The green display shows the current set temperature
chosen by the user.
5.2.2
Display of temperature control
The LED
OUT 1
indicates the status of the temperature control:
•
If LED OUT 1 is lit the temperature control is
active. The heating or cooling is switched on.
•
If LED OUT 1 is not lit the heating or cooling is
switched off.
If the LED OUT 1 lights up permanently, the calibrator
is heating up. The temperature control is active so that
the set point is reached as quickly as possible.
If the set temperature has almost been reached,
the LED OUT 1 begins to flash.
The temperature control is activated at
increasingly shorter intervals. Thereby, a too
strong overdriving is prevented.
To ensure good temperature stability, the cycle
time of the controller is set low.
The temperature control is now often activated
but only for a short time.
Display of reference and set
temperature
Temperature control active
The control is done by PID algorithm.
