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
