  • GDM-8351 Dual disy digital electric meter

    Model:GDM-8351

    Brand:固纬Gwinstek

    Introduction:Cushman Electronics has introduced a new 5 1/2 dual disy digital meter, the GDM-8351, to rece the previous model of the same class, the GDM-8251A. The new meter also uses a VFD dual disy with a maximum disy of 120,000 digits,0.02percent basic accuracy of DC voltage and a USB/RS232C communication interface, providing users with accurate measurement functions, clear numerical observation and easy access to a personal computer.

    • 120,000 digits,VFD disy

    • Dual measurement/dual disy

    • Dc voltage (DCV) basic accuracy: 0.012percent

    • Measurement speeds are optional, up to 320 reads/second

    • True RMS(AC,AC DC) measurement

    • Automatic/manual shift is optional

    • 11 measuring functions: AC-DC voltage, AC-DC current, 2-wire / 4-wire resistance, short-circuit buzzer, diode measurement, capacitance, frequency, temperature

    • Various auxiliary measurement functions: Max./Min., REL/REL

    • Digital I/O offers dual modes (standard compare and user defined modes)

    • Standard port RS-232C and USB device(supports USBCDC and USBTMC modes)
