The GD128PLUS is a smart rechargeable True RMS digital multimeter designed for fast, accurate troubleshooting in electrical work, electronics and advanced DIY. It features a 9999-count VA color HD display with an analog bar, clear range/gear indication and input jack guidance, so measurements are easy to read and safer to perform. With auto ranging plus optional manual control and a fast ~3 readings per second update rate, it works smoothly in real service conditions.
This model measures AC/DC voltage, AC/DC current, resistance, capacitance, frequency, duty cycle and temperature, and it includes practical diagnostics such as NCV non-contact voltage, live wire detection, continuity beep, diode test, REL measurement, MAX/MIN, data hold, flashlight, low-battery indication, fuse burn prompt and auto power off. Power comes from an internal 3.7V rechargeable lithium battery, so you don’t need disposable AAA cells.
