The unit now starts and controls to the set value� When
the temperature has reached the set value and has be-
come constant, the “Set” LED (C) no longer flashes and
the following display appears� The temperature measured
by the unit appears on the left hand side�
Input the calibration value from the reference measuring
instrument (e�g� 10�1 °C) with “Pump (+)” button (J) or
“Pump (-)” button (K)�
Confirm the value by pressing the “OK/Pump“ button (I)�
Back to previous screen for input a new value by pressing
“Temp” button (L)�

OK
The first point calibration is finished now�
Calibration of the other points is performed in the same
way�
Example: 2-point calibration:
Dip the temperature sensor of the reference measuring
instrument into the bath fluid�
Select 2-point calibration in the menu� Press the “OK/
Pump“ button (I) to start the 2-point calibration�

RS 232 interface:
Configuration:
- The functions of the interface connections between the
stirrer machine and the automation system are chosen
from the signals specified in EIA standard RS 232 in ac-
cordance with DIN 66 020 Part 1�
- For the electrical characteristics of the interface and the al-
location of signal status, standard RS 232 applies in accor-
dance with DIN 66 259 Part 1�
- Transmission procedure: asynchronous character transmis-
sion in start-stop mode�
- Type of transmission: full duplex�
- Character format: character representation in accordance
with data format in DIN 66 022 for start-stop mode� 1
start bit; 7 character bits; 1 parity bit (even); 1 stop bit�
- Transmission speed: 9600 bit/s�
- Data flow control: none
- Access procedure: data transfer from the stirrer machine to
the computer takes place only at the computer’s request�
