Transport, packaging, and storage
5.1.
Transport
Check if the portable Dry Well Calibrator shows any damage caused during transport. Report any
evident damages immediately to the carrier.
5.2.
Packaging
Do not remove the packaging until the unit is ready to be installed. Keep the packaging for future
use, in the event that the installation site changes or if the product is shipped for service or
calibration.
5.3.
Storage
Permissible conditions for storage
•
Storage temperature: - 10 … +60 °C / 14 … 140°F
•
Humidity: 30….95% relative humidity (non-condensing)
Avoid the following
•
Direct sunlight or proximity to hot objects

Commissioning / Operation
6.1.
Scope of use – Calibration of temperature sensors
Calibration of temperature sensors is accomplished by placing a Standard Instrument (Reference
Device) into the Dry Well at the same depth as the Device Under Test (DUT). By comparing the
temperature indicated on the Standard Instrument with the DUT, you can determine the
calibration accuracy of the DUT sensor. If the accuracy requirements permit, the local display on
the Dry Well may be used as the Standard Instrument.
WARNING
Grounded Thermocouples may display erroneous measurements due to ground
loops. Grounded thermocouple measurements must be validated to determine if
erroneous measurements from ground loops are present.
6.2.
Operating Position
The portable Dry Well Calibrator must be operated in a vertical position and should never be used
in the horizontal position as temperature uniformity may be adversely affected.
