4 1/2 (19999 Counts) LED Single Display.
In terms of cost/performance
ratio, the GDM-8145 yields one of the best choices among the DMMs in
today's market. It is equipped with 4 1/2 digits, and a
0.5" LED display in a distinctive red color. Measurement items
include DC Voltage/Current, AC Voltage/Current with true RMS, Resistance
and Diode Test. The true RMS AC and AC+DC response give accurate
measurements for equivalent DC energy regardless of the waveform shape.
Small voltage offsets are canceled by the auto-zero circuit, and
protection mechanisms are available for the entire measurement range.
All these features provide user with a robust measurement experience.
