JULABO FP51-SL Ultra-Low Refrigerated Circulators - Manual (Page 60)

Menu functions
60
9.7.1. ATC Fühler - intern / extern
In the first submenu the ATC function is set for the >intern< internal or the
>extern< external temperature sensor.
Calibration can be carried out for the internal temperature sensor and for
the external temperature sensor connected to the socket „ext. Pt100“.
The circulator is able to save both parameter sets. However only the one
which has been set under menu item > sensor < is displayed.
9.7.2. ATC Status - yes / no
In the second submenu the ATC function for the temperature sensor
selected above is activated >yes< or deactivated >no<.
>yes< (factory setting) The controller of the circulator uses the original
curve of the temperature sensor or the new curve measured during
the ATC calibration.
Important: Set to >NO< during the calibration process
>no< An ATC calibration is to be carried out.
Important: Set to >yes< after calibration.

In the > Status < >yes< the ATC calibration always affects the current
working temperature; also the one set via interface.
9.7.3. Type 1 -/ 2 -/ 3 point
A >1-point<, >2-point< or >3-point< calibration can be carried out.
First geometrically define the location for calibration (measuring point
CT), then determine the temperature values of the calibration points.
The type of calibrations also determines the number of the following pairs
of values indicated on the LCD DIALOG-DISPLAY.
Pairs of values:
TmpValue X: Circulator temperature 1 or 2 or 3 (actual value TT )
The actual temperature of the bath is simultaneously saved with the
“calibration value“ >CalValue< and can be indicated for control
purposes (value does not flash).
CalValue X: Calibration temperature 1 or 2 or 3 (actual value CT )
The „calibration value“ is determined with a temperature measuring
device and saved under menu item >CalValue<.
