전기/전자계측기Dual Channel Digital Multimeter Prova-901/902

  

 

Prova-901/902

 

●60,000 counts and dual input channels (4-5/6 digits)
●0.03% DC basic accuracy and 0.1% AC basic accuracy
●Bandwidth of 200 KHz(max.) and true RMS
●Fast ACV, ACA response
●Better AC accuracy than that of a bench-top DMM
●Study of 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-232 interface
●Standalone data logging of 10,708 records for both channels (903)
