|
Dual Channel Datalogging Digital Multimeter Prova-903(RS-232,RMS) |
● 제품특징
- 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)
