3 Set-up and putting into operation
When unpacking the device, make sure you also remove the accessories from the packaging.
Please contact the manufacturer if any parts are missing, and the forwarding agent or supplier in case of
any visible damage.
Place the laboratory hot plate on a flat, horizontal and non-slip surface, which should not be surrounded
by any combustible materials. A space of at least 0.5 m must be left clear on all sides of the hot plate.
Insert a 10 mm ∅ ∅ ∅ ∅ tripod rod into the holder on the back (M8 female thread) and tighten the tripod rod
manually.
Before connecting to the mains, check that the details on the rating plate agree with the mains voltage!
Plug the mains cable into the integrated European-type socket in the back panel of the laboratory hot plate.
After connecting the cable to the mains, the sensor, glass-ceramic and ambient conditions will be
automatically calibrated. The "KeyLock" LED lamp will light up during this process.
During calibration, the glass-ceramic surface in the vicinity of the sensors must not be covered with any
objects, nor may the area around the sensors be exposed to any strong light source such as sunlight,
powerful halogen lamps, etc. The "Keylock" LED lamp will briefly light up to indicate that the laboratory hot
plate is being supplied with mains voltage.
General information, correct use
The decoration marks the centre of the heating surface. However, the surface outside the decorated area
also becomes hot. You can quickly interrupt the heating process by simply moving the vessel out of the
hot zone to colder adjacent areas.
The laboratory hot plate is equipped with a 2-stage residual-heat indicator << H >> and << h >>. The
<< H >> display lights up immediately after the hot laboratory hot plate has been switched off. After a short
time, the display will change to << h >> indicating that there is no longer any significant residual heat.
Likewise, residual heat will be indicated after about 10 seconds at the << 0 >> heat intensity setting. As
long as the << H >> symbol is illuminated, the switched off heating zone of the laboratory hot plate is still
hot and can be used to save energy. This residual-heat indicator warns of the risk of burning. Once the hot
plate has cooled down sufficiently, the residual-heat indicator will go off. Caution! If you pull the mains plug
out of the mains socket or in case of a power failure, the residual-heat indicator will stop functioning. As
soon as the heating process is resumed, the residual-heat indicator will be reactivated.

Caution: Danger of burning!
Always disconnect the laboratory hot plate after use.
After 5 hours of heating at the << 9 >> setting without the sensor surface being touched, the safety cut-out
circuit will switch off the laboratory hot plate. When used at a heat intensity between << 1 >> and << 8 >>,
the laboratory hot plate will be switched off by the safety cut-out circuit after 120 hours to prevent the
glass-ceramic heating surface from overheating. The over-temperature protection facility protects the
laboratory hot plate against overheating.
If several sensor keys are touched within 1 second, the laboratory hot plate interprets this as an operating
error, which is ignored (safety measure). An interval of at least 2 seconds must be left between touching
keys.
Please observe the instructions for cleaning and care. In particular, you should keep the fields of the
sensor keys clean, as soiling here may be misinterpreted as finger contact.
If sugar, plastic or aluminium foil accidentally come into contact with the hot spots of the heating surfaces,
do not under any circumstances switch the laboratory hot plate off, but immediately remove these
substances with a razor-blade scraper.
