5.3 Storage
Permissible conditions at the place of storage:
Storage temperature: 0 ... 70 °C (32 ... 158 °F)
■
Humidity: 35 ... 85 % relative humidity (no condensation)
■
Avoid exposure to the following factors (terminal side, connection head):
EN
Direct sunlight or proximity to hot objects
■
Mechanical vibration, mechanical shock (putting it down hard)
■
Soot, vapour, dust and corrosive gases
■
Potentially explosive environments, flammable atmospheres
■
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. Place the instrument, along with shock-absorbent material, in the packaging.
2. If stored for a prolonged period of time (more than 30 days), place a bag, containing a
desiccant, inside the packaging.
6. Commissioning, operation
WARNING!
When the thermocouple is installed, 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!
Thermocouples must be earthed (grounded) if dangerous voltages could be
expected at the connection wires (caused, for example, by mechanical damage,
electrostatic discharge or induction)!
