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 1mm2 of harmonised code
H05W-F connected to an IEC 320 plug should be used.
N.B. The U.K. 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
main supply.

THIS OPERATION SHOULD ONLY BE UNDERTAKEN
BY A QUALIFIED ELECTRICIAN

General Description

The Stuart SMP10 and SMP20 have 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 the unit for the first time

Once the unit is unpacked, select the appropriate
choice of self adhesive instruction label from the multi­language set provided. Peel off the backing and stick
the label onto the left side of the fascia. Apply the label
carefully using a flat object to smooth away air bubbles.

Principle of Operation

The SMP10 and SMP20 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.

SMP10 only

Once measuring is started the SMP10 will heat slowly
(2°C per minute) from the plateau temperature until
the melt occurs. This slow rate of heating allows very
accurate melting points to be obtained.

SMP20 only

It is possible to adjust the ramp rate of the SMP20,
between 1ºC per minute and 10ºC per minute. This
allows either a fast result to be obtained or a more
accurate slow one

Before Use

Place the unit on a firm, level surface and extend the
feet at the rear of the instrument so that the unit is
at a convenient viewing angle. Connect to the mains
electricity supply and switch on by means of the mains
on/off switch. The actual block temperature will now
be shown on the LED display and the illumination in
the sample chamber will come on.

Measuring a Melting Point

N.B. If the unit has been used recently the block may
be too hot for your sample. If this is the case press
the stop button and allow the unit to cool before
proceeding.

1. Prepare sample by placing a small amount in the
end of a glass capillary tube.

2. Decide on a suitable plateau temperature. This
should be approximately 10°C below the expected
melting point of the sample.

3. Check that all 3 function lights are extinguished.
If not, press the stop button.

4. Press and hold the plateau set button (the plateau
light will flash). The display will now show the
current plateau temperature.

5. The desired plateau temperature may now be set
using the arrow keys to scroll the display up
or down as required.

6. Release the set button. The new plateau
temperature is now set and all function lights
will go out (The plateau setting can be checked at
any time during operation by pressing and holding
the plateau set button). This action will not
interfere with the operation of the unit).

7. SMP20 only – Decide on an appropriate ramp rate,
between 1ºC per minute and 10ºC/min. Results
obtained at 1ºC per minute will be the most
accurate, while more approximate results can
be obtained faster at higher ramp rates.

Setting the ramp rate is the same procedure as setting
the plateau except you need to use the ramp set button
instead of the plateau set button.

8. Insert the tube into the side of the heating block
via the holes provided. For convenience this can
be done from either side of the block. Look down
the magnifier and position the tube so that the
sample can be observed clearly.

Caution: The heating block may be HOT.

9. Press the start or stat/stop key. The unit will quickly
heat up to the plateau temperature (the heating
light will be illuminated - see figure 1)

10. Once the plateau temperature has been reached
the plateau light will be illuminated as well as
the heating light - see figure 1.

N.B. At low plateau temperatures there may be some
overshoot. Wait until the plateau light comes on before
proceeding in order to ensure that the temperature has
stabilised.

11. Press the start button again. The block will
begin to heat at the pre-set ramp rate (SMP20)

or at the fixed 2°C per minute on the SMP10
(the plateau light will go out and the ramping
and heating lights will both be illuminated - see
figure 1.)

12. Observe the sample until the melt occurs and
record the temperature from the digital display.

13. SMP20 only – It is possible to freeze the
temperature display on the SMP20 using the
hold button. Once pressed the temperature
display will hold (ramping light flashing) to allow
more time to record the melt temperature.
Press hold again to return to the actual block
temperature.

14. After the melt has occurred press the stop or start/
stop button. All function lights will go out and the
unit will cool to ambient temperature.

15. Pressing the start button again will cause
the unit to return to the plateau temperature
instead of ambient. The heating light will come on
even if the temperature is above the plateau and
the unit is, in fact, cooling.

Cleaning & Servicing

WARNING: Ensure the unit is disconnected from

the mains electricity supply and allowed to cool
before attempting any cleaning or servicing.

Cleaning

Periodically clean the instrument using a damp cloth
and mild detergent solution. Do not use harsh or
abrasive cleaning agents. Broken melting point tubes
may be removed from the block simply by pushing
them through with a piece of wire or similar tool.
For access to the block for more thorough cleaning the
sample chamber cover must be removed.

1. Remove the 3 retaining screws and lift off the
cover.

2. Loosen the screw retaining the metal plate but do
not remove completely.

3. Push the plate to one side.

4. The glass window in the top of the block may now
be removed.

Servicing

Any repairs or replacement of parts MUST only be
undertaken by suitably qualified personnel. There are
two replaceable fuses on the rear of the IEC mains
connector. The cause of any fuse failure should be
investigated and corrected.

Proceed as follows:

1) Ensure the unit is disconnected from the mains
supply.

2) Unscrew the four screws on the base of the unit
and remove the base plate. Do not disconnect or
pull on the base earth bonding wire.

3) Two fuses are mounted on the rear of the IEC
connector (both ‘Live’ and ‘Neutral’ mains
supply leads are fused). These fuses can be
removed and replaced by hand. ALWAYS
replace the fuse by ones of the correct values
shown below:
For 230V, 50Hz - T1A
For 120V, 60Hz - T1.6A

4) Refit the base and four securing screws.

Description Générale

Les appareils Stuart SMP10 et SMP20 ont été conçus
pour une sécurité et une facilité d’utilisation maximales.
La sélection de la température, la mesure et l’affichage
sont numériques, ce qui assure une parfaite précision
et permet de ne pas utiliser de thermomètre. Deux
échantillons peuvent être examinés simultanément.
Ils sont visualisés à l’aide d’une lentille grossissante
et d’un éclairage intégré. Les pieds arrières ajustables
permettent d’incliner l’appareil pour obtenir un
champ de vision optimal. Accès total au bloc pour un
nettoyage aisé.

Avant d’utiliser l’appareil pour la première fois:

Une fois déballée, choisissez l’étiquette d’instructions
adhésive appropriée à la langue du pays d’utilisation
parmi celles fournies. Décollez l’étiquette de son
support et collez-la sur le côté gauche de la face avant
de l’appareil. Appliquez celle-ci avec précaution, en
employant un objet plat pour lisser les bulles d’air.

Principe de Fonctionnement

Les appareils à point de fusion SMP10 et SMP20

ont été conçus pour donner des résultats rapides et
précis et fournir un confort d’utilisation maximal. Les
échantillons sont placés dans un tube capillaire en
verre, qui est ensuite placé dans le bloc en aluminium à
l’intérieur de la chambre de mesure. Ce bloc est chauffé
et l’échantillon est observé à travers la loupe jusqu’à ce
que la fusion se produise. La température du point de
fusion peut alors être facilement relevée sur le grand
affichage digital. Afin d’éviter une observation continue
de l’échantillon, les deux appareils sont équipés d’une
fonction “plateau”. Ceci permet de sélectionner une
température située quelques degrés en dessous du
point de fusion prévu. Ces appareils chaufferont alors
très rapidement jusqu’à cette température (20°C par
minute) et la maintiendront jusqu’à ce que l’opérateur
soit prêt à commencer l’analyse. Durant cette montée
en température, l’appareil ne nécessite pas de
surveillance particulière.

SMP10 uniquement

Une fois la mesure commencée, le SMP10 chauffera
lentement (2°C par minute), de la température
de plateau jusqu’à ce que la fusion se produise.
Cette lente montée en température permet une
détermination précise des points de fusion.
