Electrical installation
THIS EQUIPMENT MUST BE EARTHED
Before connection please ensure that the line
supply corresponds to that stated on the rating
label. Power consumption is 50W.
There is an IEC socket at the rear on the left
hand side of the instrument for connection to
the mains supply, (see figure 1). The unit is
supplied with two mains leads fitted with IEC
plugs for connection to the instrument. One has
a U.K. 3 pin plug and the other has a 2 pin
“Shuko” plug for connection to the mains
supply. Choose the lead appropriate for your
electrical installation and discard the other.
Should neither lead be suitable you should
obtain a moulded lead locally. If this is not
possible, take the lead with the U.K. plug and
replace the plug with a suitable alternative. See
the enclosed instruction sheet for advice on how
to carry out this procedure.
Should the mains lead require replacement a
cable of 1mm
2 of harmonized code H05V V-F
connected to an IEC 320 plug should be used.
N.B. The UK mains lead is protected by a 10A
fuse mounted in the plug top.
The mains lead should be connected to the
instrument BEFORE connection to the mains
supply.

General description
The sample for the melting point test is placed in
a capillary tube and inserted in to the aluminium
block inside the heater. Using the manually
adjustable heating rate, the SMP11 will rapidly
heat samples up to 20°C per minute to the melt
temperature and up to the maximum
temperature of 250°C. An accurate reading to
within 1°C of the melt temperature can be
achieved by using a slower heating rate of
between 1 and 10°C per minute. The sample is
observed through the magnifying lens until the
melt occurs and the melt temperature read from
the thermometer.
Before use
1. The SMP11 is supplied in custom-made
packaging; it is recommended that the
instrument should be kept in this packaging
between uses to maintain it in optimum
condition.
2. (First time only) Once the unit is unpacked,
select the appropriate choice of self adhesive
instruction label from the multi-language set
provided. Peel off the backing and stick the
label onto the large recessed metal area on
the right side of the SMP11 (see Fig 2).
Apply the label carefully using a flat object to
smooth away air bubbles.
