EMC INFORMATION
This product meets the requirements of the European Directive on Electromagnetic Compatibility (EMC)
89/336/EEC as amended by EC Directive 92/31/EEC and the European Low Voltage Directive 73/25/EEC, amended
by 93/68/EEC. To ensure emission compliance please ensure that any serial communications connecting leads are
fully screened.
The product meets the susceptibility requirements of EN 50082-1, criterion B.
ELECTRICAL SAFETY
This equipment must be correctly earthed.
This equipment is a Class 1 Appliance. A protective earth is used to ensure the conductive parts cannot become live
in the event of a failure of the insulation.
The protective conductor of the flexible mains cable which is coloured green/yellow MUST be connected to a suitable
earth.
The blue conductor should be connected to Neutral and the Brown conductor to Live (Line).
Warning: Internal mains voltage hazard. Do not remove the panels.
There are no user serviceable parts inside. Contact your nearest Isotech agent for repair.
Voltage transients on the supply must not exceed 2.5kV.
Conductive pollution, e.g. Carbon dust, must be excluded from the apparatus. EN61010 pollution degree 2.
The apparatus has two input connectors for temperature sensors, see Figure 1. These inputs are only suitable for
either a thermocouple or resistance thermometer. No other sensor or signal may be connected.
Environmental Ratings
Operating Temperature 5-35°C
Relative Humidity 5-95%, non condensing

HEALTH AND SAFETY INSTRUCTIONS
1. Read this entire manual before use.
2. Wear appropriate protective clothing.
3. Operators of this equipment should be adequately trained in the handling of hot and cold items and liquids.
4. Do not use the apparatus for jobs other than those for which it was designed, i.e. the calibration of
thermometers.
5. Do not handle the apparatus when it is hot (or cold), unless wearing the appropriate protective clothing and
having the necessary training.
6. Do not drill, modify or otherwise change the shape of the apparatus.
7. Do not dismantle the apparatus without disconnecting it from the supply and leaving time for it to reach
ambient temperatures.
8. Do not use the apparatus outside its recommended temperature range
9. If cased, do not return the apparatus to its carrying case until the unit has cooled.
10. There are no user serviceable parts inside. Contact your nearest Isotech agent for repair.
11. Ensure materials, especially flammable materials are kept away from hot parts of the apparatus, to prevent
fire risk.

INTRODUCTION
This patented furnace has been uniquely designed.
Introduced by Isothermal Technology in 1984, the full potential of the bath has yet to be realised.
The lower temperature limit is dictated by the controller and the furnace time constant so that by reducing the heater
power (HL) to about 5 to 10% of full power good results can be obtained even at temperatures just above room
temperature.

Saturn/Cyclops 878 Iss.05 – 08/18
THEORY OF OPERATION
The windings that heat the Cyclops are specially profiled to give a uniform area of constant temperature in the central
part of the oven or furnace.
The theory behind the Isotech Spherical Black Body Source is that a solid conducting sphere suspended in the centre
of a hollow outer, heated sphere will take up the temperature of the outer hollow heated sphere by convection and
radiation to give a very stable temperature reference, without end, or edge effects.
