PRECAUTIONS
vi 46882-311D
Fuses
Note that the internal supply fuse is in series with the live conductor of the supply lead. If
connection is made to a 2-pin unpolarized supply socket, it is possible for the fuse to become
transposed to the neutral conductor, in which case, parts of the equipment could remain at supply
potential even after the fuse has ruptured.
WARNING
Fire hazard
Make sure that only fuses of the correct rating and type are used for replacement.
If an integrally fused plug is used on the supply lead, ensure that the fuse rating is commensurate
with the current requirements of this equipment. See under ’Performance Data’ in Chapter 1 for
power requirements.
WARNING
Toxic hazards
Some of the components used in this equipment may include resins and other materials which give
off toxic fumes if incinerated. Take appropriate precautions, therefore, in the disposal of these
items.
WARNING
Lithium
A Lithium battery (or a Lithium battery contained within an IC) is used in this equipment:
As Lithium is a toxic substance, the battery should in no circumstances be crushed, incinerated or
disposed of in normal waste.
Do not attempt to recharge this type of battery. Do not short circuit or force discharge since this
might cause the battery to vent, overheat or explode.
WARNING
Beryllium copper
Some mechanical components within this instrument are manufactured from beryllium copper.
This is an alloy with a beryllium content of approximately 5%. It represents no risk in normal use.
The material should not be machined, welded or subjected to any process where heat is involved.
It must be disposed of as “special waste”.
It must NOT be disposed of by incineration.
WARNING
Lead-acid battery pack
Battery usage
A lead-acid battery pack is supplied with the instrument as an accessory. This contains both lead
and sulphuric acid. Lead is a toxic substance and sulphuric acid is corrosive and a skin irritant
which can cause chemical burn damage to exposed skin. The battery pack should in no
circumstances be disposed of in normal waste.
