feature: 1. EBTN LCD display technology: Compared with traditional LCD technology, EBTN LCD provides key performance advantages and greatly enhances the reading experience. The illuminated numbers and letters on the black background make it very easy to read, even in bright sunlight or insufficient light. in the case of. 2. Large-screen 3-line display: The 3.5-inch ultra-large screen can display 3 test results such as voltage, frequency, and analog bar. 3. Automatic identification: Designed for beginners, it can automatically identify the measured parameters and select the required range. 4. Ultra-thin design: the thickness is only 12mm, the weight is lighter, the LCD screen is larger, and it looks like a mobile phone. 5. Simple/convenient/easy to use: The multi-meter strap probe design allows you to test safely and efficiently without plugging or unplugging the probe, which not only saves learning and testing time, but also avoids incorrect port insertion. 5. Flashlight function and hanging hole: The flashlight design allows you to test efficiently and comfortably anytime and anywhere, whether indoor or outdoor, day and night. Hanging hole design makes it easier to carry. 6. One key to turn on intelligent recognition, no need to change gears, bid farewell to cumbersome. 7. Functions: AC and DC voltage test, resistance and continuity test, frequency test, capacitance test, data retention, automatic shutdown, LIVE zero line and fire line judgment, V~alert dangerous voltage alarm, true RMS, diode on-off automatic identification, Diode test current can be lit, automatic range, full range overload protection.
