3.2 Preparing the dry-block calibrator
Warning
The calibrator must not be used for any purposes other
than those described in this manual, as it might cause a
hazard.
The calibrator has been designed for indoor use only
and is not to be used in wet locations.
The calibrator is not to be used in hazardous areas,
where vapour or gas leaks, etc. may constitute a danger
of explosion.
The calibrator is not designed for operation in altitudes
above 2000 meters.
The calibrator is a CLASS I product and must be
connected to a mains outlet with a protective earth
connection. Ensure the ground connection of the
calibrator is properly connected to the protective earth
before switching on the calibrator. Always use a mains
power cable with a mains plug that connects to the
protective earth.
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 free within an area of 20
cm on all sides and 1 metre above the calibrator due to
fire hazard.
