DEVICE FOR CHECKING PARAMETERS Russian patent published in 1994 - IPC

FIELD: information-measurement systems. SUBSTANCE: system has program unit, setting and interrogating commutators, analog-to-digital converter connected with input of interrogating commutator, computational unit which has the first information input connected with information input of analog-to-digital converter and output connected with results of checking output unit, stimulating signals unit connected with setting commutator, unit of resistors connected between setting and interrogating commutators, switch which has input connected with voltage supply through resistor and input connected with input of analog-to-digital converter. Device also has failure indication unit connected with output of computational unit. Integrity of communication line may be tested as well as commutators prior to testing of object under testing. EFFECT: improved truth of checking. 3 cl, 1 tbl, 5 dwg
