    The GDM-8255A / GDM-8251A's are portable, dual-display digital multimeters with displays of 199,999 or 120,000 counts, 4 wire measurement technology and VFD display provide DCV 0.012% accuracy and excellent Contrast/ brightest display.

    These new DMM's offer an extensive list of measurement items - ACV, DCV, ACA, DCA, R, Hz, Continuity beeper, Diode test, REL, Dual display: ACV + Hz, DCV + dBm, ACV + dBm, DCV + ACV ripple and dBm.

    Additional measurement functions, such as Max/Min, Hold, Relative value and Compare, are suitable for wide range of applications, such as production testing, research, and field verification. The calibration key along with the free software enable users to calibrate GDM-8251A / GDM-8255A in an effective manner.

    The USB, RS-232C and 9-pin digital I/O interface are included as standard features, while the optional GPIB interface and 16 channel scanner x2 are also available for ATE applications.
