7 Stirring
The “stirring” function is switched on or off via rotating
stirring knob. The speed is set on the knob (100 to 1500
rpm in steps of 10 rpm). When both the heating function
and stirring are switched on and the above operations are
completed, the LCD will shift to the speed value and revert
back to the temperature value in about 5 seconds.
The last speed value set is displayed.

Turn the Function switch knob to time set interface, turn the
parameter set knob to target time, press parameter set knob,
to switch on timer function.
Attention: The heating and stirring function can be
switched on at the same time only when setting the timer
function. Otherwise, only the stirring function can be
switched on.
9 Remote Control
Figure 7
The unit can be controlled from an external PC (using the
third-party software) via the RS232C 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 EIA-standard RS232C,
corresponding with DIN66020 Part 1. The allotment of
the bushing can be taken from Figure 7.
• Transmission method: Asynchronous signal
transmission in start-stop-operation.
