Features: 1. Large screen with three displays. 2. Backlight hanging buckle. 3. Measure at power-on, intelligent identification, and automatic frequency display for AC voltage. 4. AC/DC voltage detection. 5. Non-contact AC voltage detection: In the first gear, the bar-shaped value is displayed in the L area, and the buzzer sounds an alarm. In the second gear, the bar-shaped value is displayed in the M area, and the buzzer emits a high-frequency alarm sound. In the third gear, the bar-shaped value is displayed in the H area, and the buzzer emits a higher frequency alarm sound. 6. 12mm, ultra-thin, can be carried with you. Parameter: 1.
