The B-471 time interval meter measures time intervals from 10 ns to 1000 s between pulse signals of positive or negative polarity with a pulse duration of at least 10 ns.
The meter operates in remote control mode via the USB interface of a personal computer. The operation of the meter is based on the counting-pulse principle, which consists of counting the number of pulses of the operating frequency during the measured time interval.
Areas of the potential use of the meter are experimental and production units that require registration of time intervals in the flow of events, as well as change, control and repair of measuring instruments and devices for various purposes.
The time interval meter is registered in the State Registers of Measuring Instruments of the Republic of Belarus (certificate № 4295) and Russia (Certificate № 29922).
