This equipment is a Class 1 Appliance and must be earthed (grounded). Use the supplied power cord and plug it directly into an AC outlet with a protective earth.
If using an alternative cord ensure it is of adequate rating.
If fitting a plug to the cable we have supplied the cable is colour coded as follows:
Do not use the equipment if it is not correctly earthed. If in doubt consult Isothermal Technology Ltd or a qualified electrician.

7 Cautionary Note
Operators of this equipment should be adequately trained in the handling of hot and cold items. It is important the user has been trained about the selection and use of liquids over a wide temperature range. It is expected that personnel using this equipment will be competent with the management of apparatus which may be powered or under extremes of temperature and are able to appreciate the hazards which may be associated with and the precautions to be taken with, such equipment.

8 Safety Warnings
8.1 Environmental Conditions
Operating temperature: 5-40°C (41-122°F) Relative Humidity: 5-80% - Non-condensing
8.2 Do Not Modify Or Disassemble
Do not use the apparatus for jobs other than those for which it was designed, i.e. the
calibration of thermometers
There are no user serviceable parts inside. Do not dismantle or modify the apparatus. For
repair information contact Isothermal Technology Ltd
For equipment with fans, the fan should kept free from dust build up; a soft brush or
vacuum cleaner may be used on the external grill
8.3 Beware Of Electrical Considerations
The equipment is for installation category II (transient voltages) and pollution degree
II in accordance with IEC 664 at altitudes to 2000 metres
Sensor Input Connection must never exceed 30V with reference to ground Thermostat test inputs should be voltage free: isolate from any voltage source during test
8.4 Be Careful Where It Is Used
The equipment is not for use in hazardous areas or in an environment close to flammable
materials or gases
The equipment must be used on a flat level surface, with adequate space around it for air
flow and avoid blocking ventilation slots
Ensure free space above the unit to avoid risk of burn or fire The equipment should only be used indoors Site in a way that allows access to the power switch, and to allow the cable to be
disconnected
Avoid excessive heat, humidity, dust and vibration ensuring it will not be subjected to
dripping or splashing liquids
8.5 Be Careful With Extremes Of Temperature
In normal use the calibration volume, inserts and probes will become very hot and present
a burn hazard
Do not remove inserts, probes or handle the equipment when it is hot or cold. Allow the equipment and accessories to reach a temperature between ambient and 70°C
before switching off or storing the equipment in its case
Do not use the equipment outside its recommended temperature range Operating the equipment at extremes of temperature for extended periods may call for
early replacement of the heating assembly
Wear appropriate protective clothing
8.6 Be Careful With Inserts
Only use inserts supplied with, or ordered specifically for, this model Do not handle inserts while they are very hot or cold Inserts for low temperature models may melt and cause a fire if used in high temperature
models
Only use Isotech inserts which are specially treated to avoid them from becoming stuck in
the calibration volume
Do not use powders, liquids or compounds in the insert; this may lead to the insert or
probes becoming stuck
13
9 Consider The Environment
The equipment should be recycled or disposed of in a proper way; following the Waste Electrical and Electronic Equipment (WEEE) directive

10 Introduction
The purpose of the Jupiter models is to provide an adjustable isothermal enclosure for calibration purposes. It has been designed to be rugged and easily maintained.
The isothermal enclosure consists of a fixed heater block into which an insert can be placed. Temperature sensors for calibration are placed in suitably drilled holes in the insert. The replaceable inserts enable a variety of items to be calibrated.
Additionally there are accessories to allow the calibration of surface sensors and also infrared thermometers.
The heater block houses a heater and the control sensor used by the temperature controller to sense the block temperature.
There are two electrically driven fans in the unit. One runs continuously and cools the electronics in the instrument and the other is switched to cool the block when the set temperature is lower than the block temperature.
10.1 Comparison Calibration
By definition, one compares industrial thermometers to a calibrated standard. There are three methods commonly used.
10.2 Basic Operation
Using the controller as the “calibrated standard”. This method means
that the complete bath is calibrated by comparing the controller reading to a calibrated standard placed in the bath.
This is a common method but is unsafe since the control sensor is
a) inaccessible b) in the wrong place to give correct temperature of the insert
For these reasons it fails to satisfy ISO9000 and gives large uncertainties.
10.3 Site or Self-Contained Calibrators
In these an indicator and external calibrated sensor are used to measure the temperature of the insert. This arrangement gives good results and traceability. To recalibrate however it does mean sending the whole calibrator back to the calibration laboratory. The calibrator is self­contained, self-sufficient and meets ISO9000 requirements.
