trained specialists with basic electrical knowledge.
Qualified personnel are those who can recognize
possible hazards and institute the appropriate safety
measures due to their professional training, knowledge,
and experience as well as their understanding of the
relevant regulations pertaining to the work to be done.
The operator is responsible for ensuring that local safety
regulations are observed. In particular, the operator must
take steps to ensure that a defect in the measuring system
will not result in hazards to persons or equipment.
If defects and unresolvable faults occur in the thermometer,
take it out of service and secure against unauthorized use.
General safety notes
Protection from electrostatic discharge (ESD) is required!
Proper use of grounded surfaces and personal arm bands
is required when working with exposed circuits (circuit
boards) to prevent damage to sensitive electronic
components from electrostatic discharge.
When hazardous measuring material such as oxygen,
acetylene, flammable or toxic materials, as well as
refrigeration equipment, compressors etc. are present the
relevant regulations must be observed above and beyond
all general rules.
When faults occur, aggressive media having high
temperature and under high pressure may be present.
Measuring material remnants in disassembled devices may
result in a hazard to personnel, the environment and
equipment. Take sufficient precautions!
