Inspection / functionality check readings

 

 

It is important to check all the equipment in the shipment as soon as possible after 

taking delivery and well before installation is to be carried out.  Check that all the 

components detailed on the documents are included in the shipment.  Check that the 

equipment has not been physically damaged.

 

 

CHECK the Thermistor readings against the approximate environmental temperature 

on arrival to ensure they have not been damaged during transportation. This is a 

basic 

out of the box

’ 

functional check.

DELIVERY

 

 

This section should be read by all users of Thermistors manufactured by 

Geosense

®

  

.

 

4.2 

 

Handling

 

  

Whilst they are a robust devices, Thermistors piezometers are precision measuring 

instruments.  They, and their associated equipment, should always be handled with 

care during transportation, storage and installation.

 

 

Once the shipment has been inspected (see below), it is recommended that 

Thermistors remain in their original packaging for storage or onward transportation.

 

 

Cable should also be handled with care.  Do not allow it to be damaged by sharp 

edges, rocks for example, and do not exert force on the cable as this may damage 

the internal conductors and could render an installation useless.

 

4.1 

 

Packaging

 

  

Thermistors are packed for transportation to site. Packaging is suitably robust to 

allow normal handling by transportation companies.  Inappropriate handling 

techniques may cause damage to the packaging and the enclosed equipment.  The 

packaging should be carefully inspected upon delivery and any damage MUST be 

reported to both the transportation company and 

Geosense

®

 

4.4 

 

Storage

 

 

All equipment should be stored in an environment that is protected from direct 

sunlight.  It is recommended that cables be stored in a dry environment to prevent 

moisture migrating along inside them in the event of prolonged submersion of 

exposed conductors.

 

 

Storage areas should be free from rodents as they have been known to damage 

connecting cables.

 

 

No other special requirements are needed for medium or long

-

term storage although 

temperature limits should be considered when storing or transporting associated 

components, such as readout equipment.
