* Availability of a certificate of registration of the device in the state register, including 
the availability of a verification method or reference to the standard method. 
* Availability of primary inspection certificate. There are two possible approaches. If 
one trusts the full supplier, then they can be loaded with checks - the problems for him will be 
less. If you are unsure about the supplier, however, it is best to calibrate it yourself or with an 
independent comparator. 
* Possibility to organize further metrological support of the device. If you are not able 
to test the device, will you have to work with some other lab? 
* Calibration interval. Have a possibility to perform device comparison once a year or 
once in 2, 3, 4 years. 
* Availability of repair facilities. A modern measuring instrument with a serious 
malfunction can only be repaired by an experienced repairman who specializes in this type of 
equipment. Repairs must be carried out by an authorized service center. 
* Warranty and service data of the device. 
* Availability of warranty service. 
* Year of manufacture of the device. 
* Additional materials (batteries, lamps, tapes, cables, etc.) are used in the operation of 
the device. Often, good devices can put the user at a disadvantage, especially by using very 
non-standard items that are hard to find. As you can see, you will need to gather a lot of 
information.
