2. Safety
2.4 Special hazards
WARNING!
For hazardous media such as oxygen,
acetylene, flammable or toxic gases or
liquids, and refrigeration plants, compres-
sors, etc., in addition to all standard regula-
tions, the appropriate existing codes or
regulations must also be followed.
DANGER!
Danger of death caused by electric current
Upon contact with live parts, there is a direct
danger of death.
■ The instrument may only be installed and
mounted by skilled personnel.
■ Before replacing the fuse, cleaning,
maintenance/servicing and in the event
of danger, the calibrator or the micro
calibration bath must be disconnected
by unplugging the mains cable from the
power supply outlet.
WARNING!
Residual media in the dismounted instru-
ment can result in a risk to persons, the
environment and the equipment.
Take sufficient precautionary measures.
Thermal fuse
WARNING!
■ For safety, the calibrator or the micro
calibration bath is fitted with an indepen-
dently-operating temperature fuse, which
cuts out the heater power supply if the
temperature inside the enclosure is too
high. Once the metal block and the liquid
bath have cooled down, send in the
calibrator or the micro calibration bath to
WIKA for examination.
■ The calibrator and the micro calibration
bath have been designed as measuring
and control instruments. With any opera-
tion of the calibrator/micro calibration
bath not expressly provided for in these
operating instructions, additional protec-
tive measures must be taken.
■ The calibrator or the micro calibration
bath must NOT be used in explosive
atmospheres (flammable or explosive
atmospheres) without adequate protec-
tion.
WARNING!
■ Since a malfunction of the calibrator/
micro calibration bath can cause personal
injury or damage to property, the equip-
ment must be protected by additional
electro-mechanical safeguards.
2.5 Safety instructions for using calibration liquids
Calibration liquid, water
Only use distilled water, otherwise the
calibrator tank can become strongly scaled
and soiled.
Calibration liquid, silicone oil
WARNING!
■ Only use the silicone oil recommended
here.
■ Before working with silicone oil, read
the material data safety sheet. This can
be requested from the manufacturer or
supplier.
■ When working with silicone oil, sufficient
ventilation should be ensured in the room
since it can give off pollutants.
■ Since silicone oil is hygroscopic, after
use, always close the calibration bath
using the transport cover.
■ The transport cover is fitted with a safety
valve. If the micro calibration bath is
closed when it is still warm, excessive
pressure can build up. In order to avoid
overpressuring, which could lead to
damage to the liquid bath, the safety
valve is activated at a pressure of approx.
2.5 bar. This can lead to hot vapour
escaping.
Wear safety goggles!
Do not allow silicone oil to come into contact
with the eyes.
WARNING!
Risk of burns!
Before transporting or touching the metal
block/liquid bath, make sure that it has
cooled down sufficiently, as there is an acute
fire hazard from both the metal block and
liquid bath and also from the test item.
