1. Dual mode: the multimeter supports automatic and manual mode. Press the power switch for 1 second to switch to auto mode, which can automatically measure AC/DC voltage, resistance and continuity. 2. Bright LED Flashlight: With the LED flashlight, you can test anywhere efficiently and conveniently, indoors and outdoors, day and night. 3. Live / Neutral Wire Check: Safe and easy to distinguish the live / neutral conductor by comparing the strength of the detected voltage. The wire that detects the stronger voltage signal is a live wire. 4. LCD display: greatly improve the reading experience, the illuminated numbers and letters make it very easy to read even in bright sunlight or bad light. 5. High EfficiencyOne test lead design makes measurement more efficient, especially for electronic components maintenance. You no longer have to worry about the tip of the measuring cable moving while reading the test results. Note: 1. When measuring high voltage, make sure to avoid electric shock. 2. Do not input AC or DC voltage more than 500V as this may destroy the meter. 3. Disconnect the test leads from the circuit after completing the measurement. 4. The production compliance is 600V and the maximum range is 500V. Specifications: Model: Z1 Shell material: ABS Display: LCD Maximum display value: 2000 digits.
