Storing and transporting the Calibrator  

 

 

The  following  guidelines  should  always  be 

observed when  storing  and  transporting  the 

calibrator. This will ensure that the calibrator 

remain in good working condition. 

 

Storing  

 

 

Switch  OFF  the  calibrator  using  the  power 

control switch. 

 

 

If  you  intend  to  store  the  calibrator  in  the 

Packing Box after use, you must ensure that 

the instrument has cooled to a temperature, 

at  least  close  to  10˚C  /  50˚F  ambient 

temperature before placing it in the Packing 

Box 

 

Transporting  

 

 

The  Inserts  must  be  removed  to  avoid 

damage to the instrument if the calibrator is 

to be transported to long distances
