Behaviour after power cut

After interruptions such as power failures or deliberate disconnection (e.g. timer) of the AC
outlet, the magnetic stirrer remains in stand-by-mode (no heating, no stirring). This
function is in operation when lower right of display shows "o".

Residual heat display

To reduce the risk of burns, MR Hei-End
displays the residual heat of the hotplate.
Any time the hotplate has a temperature
higher than 50°C after the rocker switch (A)
has been switched off, the warning shown
here will be displayed. The instrument will
switch off fully once the temperature has dropped below 50°C.

Connecting the interfaces

Switch the instrument off before plugging in
the interface cable.
Please use an interface cable with SUB-HDD
15 connectors and connect it to the socket
(K) on the rear panel of the instrument.

12.1 RS232 interface

program (e.g. Microsoft
suitably programmed interface to enter and
read out the parameters described in 12.1.1. Configure Interface to receive data in 7 bit
ASCII format. Sending and receiving data has to end with a line feed.
