10 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”.
11 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.
12 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
Use the RS232 interface and a suitable
program (e.g. Microsoft © Hyperterminal), or a
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.
