Vs Instruments

Vlsi digital circuit breaker timer (cbt) is in lcd display type. It is used for substation breaker time measurement i. E. With single instrument one can measure making & breaking time of r, y, b arm of a breaker at a time.

as the meter display, measured time of r, y, b. One can easily differentiate time difference between r & y, y & b, b & r.

menu driven program is user friendly, so normal electrical technician can operate the meter.

vlsi digital time interval meter (dtim01) is available in 4 digit display.

this is used for measuring 'switching time of relays', trip time & on time of circuit breaker, travel time of switch & contactor etc. It can also measure response time, time delays of electromechanical, electrical or electronic devices such as .

time interval to be measured can start by either opening or closing of a potential free contact (no or nc). The no or nc selection for start/stop is indicated by led.
