Store the instrument in its original packaging in a location that fulfils the conditions listed above. If
the original packaging is not available, pack and store the instrument as described below:
1. Wrap the instrument in an antistatic plastic film.
2. Place the instrument, along with shock-absorbent material, in the packaging.
3. If stored for a prolonged period of time (more than 30 days), place a bag containing a
desiccant inside the packaging.
WARNING!
Before storing the instrument (following operation), remove any residual media. This
is of particular importance if the medium is hazardous to health, e.g. caustic, toxic,
carcinogenic, radioactive, etc.
6. Commissioning, operation
WARNING!
When the thermometer is mounted, the temperature must not drop below the allowed
operating temperature (environment, medium) or exceed it, even when taking
convection and heat radiation into account!
WARNING!
Thermometers must be earthed if dangerous voltages could be expected at the
connection wires (caused, for example, by mechanical damage, electrostatic
discharge or induction)!
6.1 Electrical connection
CAUTION!
■ Damage to cables and wires, and to connection points must be avoided
■ Flying leads with bare ends must be finished with ferrule ends (cable preparation)
■ Both the internal capacitance and inductance must be considered
For the electrical connections of thermometers (e.g. connection circuit diagrams, tolerance
values, etc.), please refer to the appropriate data sheets. If head-mounted transmitters or digital
displays have been built into the connection housing, these data sheets must also be given
proper consideration.
