3 1/2 (1999 digits) LED, DCV basic accuracy: 0.1%

In terms of cost-effectiveness, the GDM-8145/8135 series is one of the better choices for digital multimeters in the market. This series is equipped with 4 1/2 bit (GDM-8145) or 3 1/2 bit (GDM-8135), a 0.5 "unique red LED display, and measurement items include DC voltage/current, AC true RMS voltage/current (limited to GDM-8145), resistance, diode testing, and short-circuit buzzer testing (limited to GDM-8135). Regardless of the waveform shape, accurate true effective values AC and AC+DC can be measured using equivalent energy. The automatic zero calibration circuit can eliminate small bias voltages, ensuring accurate measurement of the instrument in all gears, all of which bring users a pleasant measurement experience.
