Đồng hồ vạn năng PROVA 901, PROVA 903
Dual channels (V+V, V+A) and 60,000 counts
■ 0.03% DC voltage basic accuracy and 0.1% AC voltage basic accuracy
■ Bandwidth of 200KHz (max.), and True RMS
■ Fast ACV, ACA response
■ Better AC accuracy than that of a bench-top DMM
■ More functions than those of a bench-top DMM
■ Much lower cost than that of a bench-top DMM
■ Study the relationship of two voltages similar to a dual channels DSO
■ Study of relationship of voltage and current with one DMM
■ Dual display of frequency and duty cycle
■ Record data of both channels using a PC through the RS-232C interface
■ PROVA 903: Standalone data logging of 10708 records for both channels
