Function: Heating
The device is controlled by Digital Temperature Control Technology, which has two separate safe circuits.
The hotplate is kept at a constant temperature by a digital control circuit. The hotplate temperature can also be
monitored from a separate, adjustable safety circuit. The two temperature sensors (Pt1000) internal for
temperature control are built-in the hotplate. The single external Ptl000 can monitor the temperature of sample.
If external temperature sensors needed, it must be plugged in. Stirring bar breakaway monitoring can be set in
this mode.
.
Function: Stirring
The function "stirring" is switched ON or OFF via the rotary stirring knob. The motor speed is set on the knob
(100 to 1500 rpm in steps of 10 rpm).
When both, the function heating and stirring, are switched on and those above operations are done,
the LCD will shift to the speed value and come back to the temperature value in about 5 seconds.
Remote control:
The unit can be controlled from an external PC (using the dedicated software) via the RS232 C serial interface
fitted to the unit. Data communication from laboratory instrument to computer is only possible on demand of the
computer.
•
The functions of the interface lines between laboratory instrument and automation system are selected
from the specified signals of the ElA-standard RS232 C, corresponding with DIN66020 part 1. The
allotment of the bushing can be taken from illustration.
•
For the electrical properties of the interface lines and for the allotment of the signal status, standard
RS232 C, corresponding with DIN66259 part I applies.
•
Transmission method: Asynchronous signal transmission in start-stop-operation.
•
Mode of transmission: Fully Duplex.
•
I start bit; 7 character bits; I parity bit [straight (even]); 1 stop bit.
•
Transmission speed:9 600 bit/s
