Top Digital Multimeter

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.FEATURES
