 MEASURING ELECTRIC VARIABLES; MEASURING MAGNETIC VARIABLES (measuring physical variables of any kind by conversion into electric variables, see Note (4) following the title of class G 01; measuring diffusion of ions in an electric field, e.g. electrophoresis, electro-osmosis, G 01 N; investigating non-electric or non-magnetic properties of materials by using electric or magnetic methods G 01 N; indicating correct tuning of resonant circuits H 03 J 3/12; monitoring electronic pulse counters H 03 K 21/40; monitoring operation of communication systems H 04)
 

Notes

(1)

 This subclass covers:
 

-

 measuring all kinds of electric or magnetic variables directly or by derivation from other electric or magnetic variables;
 

-

 measuring all kinds of electric or magnetic properties of materials;
 

-

 testing electric or magnetic devices, apparatus or networks (e.g. discharge tubes, amplifiers) or measuring their characteristics;
 

-

 indicating presence or sign of current or voltage;
 

-

 NMR, EPR or other spin-effect apparatus, not specially adapted for a particular application; [5]
 

-

 equipment for generating signals to be used for carrying out such tests and measurements.
