FIELD: measurement technology. SUBSTANCE: process determining resistance of luminophor of vacuum indicator consists in measurement of voltage and current on luminophor and in determination of resistance by Ohm's law. In accordance with process current of electrons emitted by cathode is controlled, currents of anode Ia and grid Ig are measured depending on voltage on anode Va. Having determined drop of voltage on layer of luminophor resistance of luminophor is found by way of division of value of voltage drop on luminophor by value of its current. EFFECT: increased measurement accuracy. 2 dwg, 2 tbl
