Product Specification
Top Digital Multimeter

5 1/2 (199,999 Counts) VFD Dual Display.

The GDM-8255A portable precision multi-meters engage with 199,999 counts, dual-display, 0.012% DCV accuracy and 2w/4w measurement. The VFD display technology provides the excellent observation of contrast and brightness.

The GDM-8255A carry an extensive list of measurement items - ACV, DCV, ACA, DCA, R, Hz, Continuity beeper, Diode test and Temperature. The dual-display measurement items include ACV + Hz, DCV + dBm, ACV + dBm, DCV + ACV ripple and dBm. Advanced measurement functions, such as Max/Min, Hold, Relative value and Compare, are suitable for multiplicity of applications such as production testing, research and field verification. The USB, RS-232C and 9-pin digital I/O interface are included as standard features, which enable its remote controlling and data capturing for ATE applications.
