To ensure the connection to protective earth any
extension cord used must also have a protective earth
conductor.
Only use a mains power cord with a current rating as
specified by the calibrator and which is approved for the
voltage and plug configuration in your area.
Before switching on the calibrator make sure that it is
set to the voltage of the mains electricity supply.
Always position the calibrator to enable easy and quick
disconnection of the power source (mains inlet socket).
The calibrator must be kept clear within an area of 20
cm on all sides and 1 metre above the calibrator due to
fire hazard.
Never use heat transfer fluids such as silicone, oil,
paste, etc. in the dry-block calibrators. These fluids may
penetrate the calibrator and cause electrical hazard,
damage or create poisonous fumes.
The calibrator must be switched off before any attempt
to service the instrument is made. There are no user
serviceable parts inside the calibrator.
When cleaning the well or insertion tube, REMEMBER
to wear goggles when using compressed air!
About the front panel:
The connections used to test thermostats must NEVER
be connected to a voltage source.
Thermostats must not be connected to any other
voltage source during a test.
About the insertion tubes, insulation plug, well
and sensor:
Never leave hot insertion tubes which have been
removed from the calibrator unsupervised – they may
constitute a fire hazard or personal injury.
If you intend to store the calibrator in the optional
aluminium carrying case after use, you must ensure
that the instrument has cooled down to a temperature
below 100°C/212°F before placing it in the carrying
case.
