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 70W.
There is an IEC socket at the rear of the right
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 of harmonised code H05W-F
2
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.
IF IN DOUBT CONSULT A QUALIFIED
ELECTRICIAN

General Description

The Stuart SMP10 has been designed for
maximum safety and ease of use. The
temperature is selected, measured and displayed
digitally ensuring accuracy and avoiding the need
for a glass thermometer. Two samples can be
tested simultaneously. They are viewed via a
magnifying lens with clear observation aided by
built in illumination. Extendible feet allow the
unit to be operated at the optimum viewing
angle. Full access to the block allows easy
cleaning and maintenance.
Before Using your SMP10 for the first time
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 left side of the
SMP10 facia. Apply the label carefully using a flat
object to smooth away air bubbles.

Principle of Operation

The SMP10 melting point apparatus has been
designed to give both quick and accurate results
as well as maximum convenience in use.
Melting point samples are placed in a glass
capillary tube which is placed in the aluminium
block inside the sample chamber. This block is
heated and the sample observed through the
magnifying lens until the melt occurs. The
melting point temperature may then be easily
read from the large LED display.
In order to avoid the necessity to continually
watch the sample the SMP10 is equipped with a
"plateau" function. This allows a temperature to
be set a few degrees below the expected melting
point. The SMP10 will then heat to this
temperature very rapidly (20°C per minute) and
hold it until the operator is ready to begin
measuring. It can safely be left to do this
unattended.
